First operation screen determination portion 53 determines a first self-operation screen for operating MFP 100 to be displayed on display unit 161. First operation screen determination portion 53 determines the first self-operation screen in accordance with an operation by the user that is accepted by first operation accepting portion 51 described later or in accordance with an operation received from the client by first server portion 59 as described later. First operation screen determination portion 53 outputs the determined first self-operation screen to first alternative screen transmission portion 67.
First alternative screen transmission portion 67 receives the first self-operation screen from first operation screen determination portion 53. When the first status signal is not input from first select portion 63 and MFP 100 does not function as a server, first alternative screen transmission portion 67 outputs the first self-operation screen input from first operation screen determination portion 53 to first display control portion 55. When the first status signal is input from first select portion 63, and, while MFP 100 functions as a server, the first self-operation screen input from first operation screen determination portion 53 is a predetermined first specific operation screen, first alternative screen transmission portion 67 outputs a predetermined first alternative screen corresponding to the first specific operation screen to first server portion 59 in place of the first specific operation screen and outputs the first specific operation screen to first display control portion 55. First server portion 59 transmits the first alternative screen to portable information apparatus 200 functioning as a client through communication I/F unit 112. Therefore, portable information apparatus 200 displays the first alternative screen without displaying the first specific operation screen.
While MFP 100 functions as a server, first alternative screen transmission portion 67 also outputs a drive instruction to first switch portion 65 in response to input of the first specific operation screen from first operation screen determination portion 53.
First server portion 59 communicates with portable information apparatus 200 functioning as a client through communication I/F unit 112 and functions as a server remotely operated by portable information apparatus 200. Specifically, first server portion 59 transmits the first self-operation screen or the first alternative screen input from first alternative screen transmission portion 67 as the first remote operation screen to portable information apparatus 200. When receiving positional information indicating a position in the first self-operation screen (first remote operation screen) from portable information apparatus 200, first server portion 59 accepts an instruction by the user who operates portable information apparatus 200, based on the received positional information.
The operation accepted by first server portion 59 is the same as the operation accepted by operation unit 163 when the user operates MFP 100 using operation unit 163. More specifically, the operation accepted by first server portion 59 is determined by the first self-operation screen. In a case where the first self-operation screen is a screen for setting a setting value, an operation for setting a setting value is accepted. In a case where the first self-operation screen has a button to which an instruction to execute a process is allocated, an operation for giving an instruction to execute a process is accepted when the position of the button is received. When the accepted operation is an operation for giving an instruction to execute a process, first server portion 59 outputs a command for executing a process to first process execution portion 57.
First client portion 61 communicates with portable information apparatus 200 functioning as a server through communication I/F unit 112 and functions as a client remotely operating portable information apparatus 200. Specifically, first client portion 61 receives the second remote operation screen for the user to remotely operate portable information apparatus 200 from potable information apparatus 200 and outputs the received second remote operation screen to first display control portion 55. First display control portion 55 controls display unit 161 and allows display unit 161 to display an image. First display control portion 55 allows display unit 161 to display the second remote operation screen input from first client portion 61. Therefore, the user who operates MFP 100 can remotely operate portable information apparatus 200 while viewing the second remote operation screen displayed on display unit 161.
First client portion 61 receives positional information indicating a position in the second remote operation screen from first remote operation accepting portion 87 described later. When the user touches the second remote operation screen with the finger, first remote operation accepting portion 87, which will be detailed later, outputs positional information indicating the position in the second remote operation screen to first client portion 61 based on the positional information input from touch panel 165. First client portion 61 transmits the positional information input from first remote operation accepting portion 87 to portable information apparatus 200 through communication I/F unit 112.
First display control portion 55 allows display unit 161 to display the first self-operation screen input from first alternative screen transmission portion 67. When the second status signal is input from first select portion 63, first display control portion 55 receives the second remote operation screen from first client portion 61 and allows display unit 161 to display a screen in which the first self-operation screen and the second remote operation screen are arranged side by side. Therefore, when the second status signal is input from first select portion 63, in other words, when MFP 100 functions as a client, the first self-operation screen and the second remote operation screen are displayed simultaneously on display unit 161, so that the user can operate MFP 100 and can also remotely operate portable information apparatus 200 while viewing display unit 161.
First display control portion 55 outputs display information to first operation accepting portion 51. In a case where only the first self-operation screen is displayed on display unit 161, the display information includes operation screen identification information for identifying the first self-operation screen and positional information indicating the position of the first self-operation screen in the display surface of display unit 161. In a case where the first self-operation screen and the second remote operation screen are displayed on display unit 161, the display information includes positional information indicating the position of the second remote operation screen in the display surface of display unit 161, in addition to operation screen identification information for identifying the first self-operation screen and positional information indicating the position of the first self-operation screen in the display surface of display unit 161.
First switch portion 65 switches operation modes of display unit 161 based on the first status signal input from first select portion 63. The operation modes of display unit 161 include a normal mode and a power saving mode in which power consumption is smaller than in the normal mode. The power saving mode includes a state in which display unit 161 displays no image and includes a case where power is not supplied to display unit 161. In response to input of the first status signal from first select portion 63, first switch portion 65 switches the operation mode of display unit 161 from the normal mode to the power saving mode. Therefore, when the first select portion 63 outputs the first status signal, in other words, when MFP 100 functions as a server, the operation mode of display unit 161 is switched to the power saving mode, thereby reducing power consumption while MFP 100 functions as a server.
When a drive instruction is input from first alternative screen transmission portion 67 with the operation mode switched to the power saving mode, first switch portion 65 switches the operation mode of display unit 161 from the power saving mode to the normal mode.
First operation accepting portion 51 receives display information from first display control portion 55 and accepts an operation input by the user. The operation input by the user includes a self-operation that is an operation on the MFP itself and a remote operation that is an operation on the portable information apparatus. First operation accepting portion 51 includes a first detection portion 81 for detecting a position designated by the user on the display surface of display unit 161, a first determination portion 83 for determining the self-operation or the remote operation based on the detected position, a first remote operation accepting portion 87 for accepting the remote operation based on the determination result, a self-operation accepting portion 85 for accepting the self-operation based on the determination result, and a first temporary storage portion 89.
First detection portion 81 is connected to touch panel 165 and receives from touch panel 165 a coordinate value of the position designated by the user on the display surface of display unit 161. First detection portion 81 outputs the coordinate value input from touch panel 165 to first determination portion 83.
First determination portion 83 determines whether the position indicated by the coordinate value input from first detection portion 81 belongs to the first self-operation screen or the second remote operation screen, based on the display information input from first display control portion 55. When the position indicated by the coordinate value input from first detection portion 81 belongs to the first self-operation screen, first determination portion 83 determines as the self-operation. When the position indicated by the coordinate value input from first detection portion 81 belongs to the second remote operation screen, first determination portion 83 determines as a remote operation.
When it is determined as the self-operation, first determination portion 83 converts the coordinate value input from first detection portion 81 into a coordinate value indicating the position in the self-operation screen and outputs positional information including the converted coordinate value to first self-operation accepting portion 85. When it is determined as the remote operation, first determination portion 83 converts the coordinate value input from first detection portion 81 into a coordinate value indicating the position in the second remote operation screen and outputs positional information including the converted coordinate value to first remote operation accepting portion 87.
First self-operation accepting portion 85 includes a first setting accepting portion 91, a first coordination instruction accepting portion 93, and a first copy instruction accepting portion 95. First setting accepting portion 91 accepts an operation by the user, based on the first self-operation screen specified by the display information input from first display control portion 55 and the positional information input from first determination portion 83. The operation by the user is determined by the first self-operation screen specified by the display information input from first display control portion 55. In a case where the first self-operation screen is a screen for setting a setting value, an operation for setting a setting value is accepted. In a case where the first self-operation screen has a button to which an instruction to execute a process is allocated, an operation of giving an instruction to execute a process is accepted when the positional information indicating the position of the button is input. When the accepted operation is an operation of giving an instruction to execute a process, first setting accepting portion 91 outputs a process execution instruction to first process execution portion 57.
First coordination instruction accepting portion 93 accepts the user's operation of selecting one of portable information apparatus 200 and MFP 100 as a client in a state in which the coordination setting screen shown in
First copy instruction accepting portion 95 accepts an operation of designating a character string included in the first self-operation screen and outputs the designated character string to first temporary storage portion 89. First temporary storage portion 89 temporarily stores the character string input from first copy instruction accepting portion 95 into a buffer. When the user inputs a copy instruction to copy a character string, first copy instruction accepting portion 95 accepts the copy instruction and specifies the character string included in the first self-operation screen based on the positional information input from first determination portion 83. First copy instruction accepting portion 95 accepts a copy instruction when the same positional information is continuously input from first determination portion 83 for a prescribed time T1 or longer. A copy instruction may be accepted when a time period during which the same positional information is input from first determination portion 83 is equal to or shorter than a prescribed time. A copy instruction may be accepted when a predetermined key provided in operation unit 163 is designated.
First remote operation accepting portion 87 outputs the positional information input from first determination portion 83 to first client portion 61. First remote operation accepting portion 87 includes a first output portion 97 and a first paste position accepting portion 99.
First paste position accepting portion 99 accepts the position specified by the positional information input from first determination portion 83 as a paste position if a character string is stored in the buffer by first temporary storage portion 89. First paste position accepting portion 99 outputs positional information including the coordinate value of the paste position to first output portion 97.
In response to input of the positional information including the coordinate value of the paste position from first paste position accepting portion 99, first output portion 97 reads out the character string stored by first temporary storage portion 89 from the buffer and outputs a set of the positional information including the coordinate value of the paste position and the character string to first client portion 61. When the set of the positional information and the character string is input, first client portion 61 assumes that the character string is input to the paste position specified by the positional information in the second remote operation screen. Specifically, the character string and the positional information are transmitted to portable information apparatus 200 functioning as a server. Accordingly, the character string included in the first self-operation screen displayed on display unit 161 can be input to the paste position in the second remote operation screen displayed on display unit 161.
Specific operation reception portion 71 controls communication I/F unit 112 to receive specific operation information from portable information apparatus 200 functioning as a client and output the received specific operation information to process determination portion 73. The specific operation information, which will be detailed later, includes positional information indicating the position in the first self-operation screen determined by first operation screen determination portion 53, and the amount of change.
Process determination portion 73 receives the first self-operation screen from first operation screen determination portion 53 and receives the specific operation information from specific operation reception portion 71. Process determination portion 73 determines a process based on the first self-operation screen and the specific operation information. Specifically, process determination portion 73 specifies, among operations that can be input on the first self-operation screen, an operation allocated to the position in the first self-operation screen as specified by the positional information included in the specific operation information, or an operation corresponding to an image at a position in the first self-operation screen as specified by the positional information included in the specific operation information, with designation of the amount of change. For example, the position in the first operation screen as specified by the positional information included in the specific operation information is in an image, an operation of enlarging or reducing the image is specified. If the amount of change is positive, an operation of enlarging is specified. If the amount of change is negative, an operation of reducing is specified. When the position in the first operation screen as specified by the positional information included in the specific operation information is in a region in which a parameter is input, an operation of increasing or reducing the parameter is specified.
Process determination portion 73 outputs a command for executing a process corresponding to the specified operation, a parameter determined by the amount of change included in the specific operation information, and data identification information for specifying data to be processed, to first process execution portion 57. Here, a case where an operation of enlarging an image included in the first self-operation screen is specified will be described by way of example. In this case, the data identification information of the image included in the first self-operation screen, an enlarge command for executing a process of enlarging the image, and a magnification are output to first process execution portion 57.
First process execution portion 57 executes a process based on the command and the parameter, where the data specified by the data identification information input from process determination portion 73 is set as a process target. Accordingly, the image included in the first self-operation screen is enlarged. First operation screen determination portion 53 determines the first self-operation screen with the enlarged image, as the next screen to be displayed. First server portion 59 transmits the first self-operation screen with the enlarged image to portable information apparatus 200 functioning as a client. Accordingly, the first self-operation screen with the enlarged image appears as the first remote operation screen at portable information apparatus 200 functioning as a client.
As described above, while MFP 100 functions as a server, in response to input of a predetermined first specific operation screen from first operation screen determination portion 53, first alternative screen transmission portion 67 outputs a predetermined first alternative screen corresponding to the first specific operation screen, in place of the first specific operation screen, to first server portion 59, outputs the first specific operation screen to first display control portion 55, and outputs a drive instruction to first switch portion 65. The first specific operation screen is, for example, a screen that prompts for an operation on MFP 100 functioning as a server. For example, the screen prompts for an operation of inserting a memory stick to a memory connection socket provided at the operation panel of MFP 100. In the following, the predetermined first self-operation screen is called a direct operation instruction screen.
Thus, first server portion 59 transmits the first alternative screen to portable information apparatus 200 functioning as a client, so that portable information apparatus 200 displays the first alternative screen without displaying the first specific operation screen. When a drive instruction is input from first alternative screen transmission portion 67 to first switch portion 65, the first specific operation screen is output to first display control portion 55. In order to allow display unit 161 to display the first specific operation screen, first switch portion 65 switches the operation mode of display unit 161 to the normal mode.
Second select portion 263 selects one of a first state in which second server portion 259 can communicate with MFP 100 functioning as a client and a second state in which second client portion 261 can communicate with MFP 100 functioning as a server while wireless LAN I/F 218 can communicate with MFP 100.
When selecting the first state, second select portion 263 outputs a first status signal to second switch portion 265, second server portion 259, and second alternative screen transmission portion 267 and outputs the apparatus identification information of MFP 100 functioning as a client to second server portion 259. When selecting the second state, second select portion 263 outputs a second status signal to second switch portion 265, second client portion 261, and second display control portion 255 and outputs the apparatus identification information of MFP 100 functioning as a server to second client portion 261.
Second select portion 263 outputs a coordination setting screen to second display control portion 255 and allows display unit 216 to display the coordination setting screen. The coordination setting screen is similar to that shown in
When the coordination instruction indicating functioning as a server is input, second select portion 263 selects the first state and outputs the first status signal and the apparatus identification information of MFP 100 functioning as a client to second server portion 259. In response to input of the first status signal, second server portion 259 is activated and communicates with MFP 100 through wireless LAN I/F 218. Second server portion 259 may be resident in CPU 211. In this case, second server portion 259 communicates with MFP 100 through wireless LAN I/F 218 in response to input of the first status signal.
When the coordination instruction indicating functioning as a client is input, second select portion 263 selects the second state and outputs the second status signal and the apparatus identification information of MFP 100 functioning as a server to second client portion 261. In response to input of the second status signal, second client portion 261 is activated and communicates with MFP 100 through wireless LAN I/F 218.
Second server portion 259 may start communication in response to a request from MFP 100 functioning as a client. Second select portion 263 selects the first state when it is detected that second server portion 259 starts communication with MFP 100 functioning as a client. Second client portion 261 may be activated in response to a request from MFP 100 functioning as a server, and second client portion 261 may start communication with MFP 100. Second select portion 263 selects the second state when it is detected that second client portion 261 starts communication with MFP 100 functioning as a server.
Second operation screen determination portion 253 determines a second self-operation screen for operating portable information apparatus 200 to be displayed on display unit 216. Second operation screen determination portion 253 determines the second self-operation screen in accordance with an operation by the user that is accepted by second operation accepting portion 251 described later or in accordance with an operation received from the client by second server portion 259 as described later. Second operation screen determination portion 253 outputs the determined second self-operation screen to second alternative screen transmission portion 267.
Second alternative screen transmission portion 267 receives the second self-operation screen from second operation screen determination portion 253. When the first status signal is not input from second select portion 263 and portable information apparatus 200 does not function as a server, second alternative screen transmission portion 267 outputs the second self-operation screen input from second operation screen determination portion 253 to second display control portion 255. When the first status signal is input from second select portion 263, and, while portable information apparatus 200 functions as a server, the second self-operation screen input from second operation screen determination portion 253 is a predetermined second specific operation screen, second alternative screen transmission portion 267 outputs a predetermined second alternative screen corresponding to the second specific operation screen to second server portion 259 in place of the second specific operation screen and outputs the second specific operation screen to second display control portion 255. Second server portion 259 transmits the second alternative screen to MFP 100 functioning as a client through wireless LAN I/F 218. Therefore, portable information apparatus 200 displays the second alternative screen without displaying the second specific operation screen.
While portable information apparatus 200 functions as a server, second alternative screen transmission portion 267 also outputs a drive signal to second switch portion 265 in response to input of the second specific operation screen from second operation screen determination portion 253.
Second server portion 259 communicates with MFP 100 functioning as a client through wireless LAN I/F unit 218 and functions as a server remotely operated by MFP 100. Specifically, second server portion 259 transmits the second self-operation screen or the second alternative screen input from second alternative screen transmission portion 267 as the second remote operation screen to MFP 100. When receiving positional information indicating a position in the second self-operation screen (second remote operation screen) from MFP 100, second server portion 259 accepts an instruction by the user who operates MFP 100 based on the received positional information. The operation accepted by second server portion 259 is the same as the operation accepted by operation unit 217 when the user operates portable information apparatus 200 using operation unit 217.
Second client portion 261 communicates with MFP 100 functioning as a server through wireless LAN I/F 218 and functions as a client remotely operating MFP 100. Specifically, second client portion 261 receives the first remote operation screen for the user to remotely operate MFP 100 from MFP 100 and outputs the received first remote operation screen to second display control portion 255. Second display control portion 255 controls display unit 216 and allows display unit 216 to display an image. Second display control portion 255 allows display unit 216 to display the first remote operation screen input from second client portion 261. Therefore, the user who operates portable information apparatus 200 can remotely operate MFP 100 while viewing the first remote operation screen displayed on display unit 216.
Second client portion 261 receives positional information indicating a position in the first remote operation screen from second remote operation accepting portion 287 described later. When the user touches the first remote operation screen with the finger, second remote operation accepting portion 287, which will be detailed later, outputs positional information indicating the position in the first remote operation screen to second client portion 261 based on the positional information input from touch panel 217A. Second client portion 261 transmits the positional information input from second remote operation accepting portion 287 to MFP 100 through wireless LAN I/F 218.
Second display control portion 255 allows display unit 216 to display the second self-operation screen input from second alternative screen transmission portion 267. When the second status signal is input from second select portion 263, second display control portion 255 receives the first remote operation screen from second client portion 261 and allows display unit 216 to display a screen in which the second self-operation screen and the first remote operation screen are arranged side by side. Therefore, when the second status signal is input from second select portion 263, in other words, when portable information apparatus 200 functions as a client, the second self-operation screen and the first remote operation screen are displayed simultaneously on display unit 216, so that the user can operate potable information apparatus 200 and can also remotely operate MFP 100 while viewing display unit 216.
Second display control portion 255 outputs display information to second operation accepting portion 251. In the case where only the second self-operation screen is displayed on display unit 216, the display information includes operation screen identification information for identifying the second self-operation screen and positional information indicating the position of the second self-operation screen in the display surface of display unit 216. In the case where the second self-operation screen and the first remote operation screen are displayed on display unit 216, the display information includes positional information indicating the position of the first remote operation screen in the display surface of display unit 216, in addition to operation screen identification information for identifying the second self-operation screen and positional information indicating the position of the second self-operation screen in the display surface of display unit 216.
Second switch portion 265 switches operation modes of display unit 216 based on the first status signal input from second select portion 263. The operation modes of display unit 216 include a normal mode and a power saving mode in which power consumption is smaller than in the normal mode. The power saving mode includes a state in which display unit 216 displays no image and includes a case where power is not supplied to display unit 216. In response to input of the first status signal from second select portion 263, second switch portion 265 switches the operation mode of display unit 216 from the normal mode to the power saving mode. Therefore, when portable information apparatus 200 functions as a server, the operation mode of display unit 216 is switched to the power saving mode, thereby reducing power consumption while portable information apparatus 200 functions as a server.
When a drive instruction is input from second alternative screen transmission portion 267 with the operation mode switched to the power saving mode, second switch portion 265 switches the operation mode of display unit 216 from the power saving mode to the normal mode.
Second operation accepting portion 251 receives display information from second display control portion 255 and accepts an operation input by the user. Second operation accepting portion 251 includes a second detection portion 281 for detecting a position designated by the user on the display surface of display unit 216, a second determination portion 283 for determining a self-operation or a remote operation based on the detected position, a second remote operation accepting portion 287 for accepting the remote operation based on the determination result, a second self-operation accepting portion 285 for accepting the self-operation based on the determination result, and a second temporary storage portion 289.
Second detection portion 281 is connected to touch panel 217A and receives from touch panel 217A coordinate values of one or more positions designated by the user on the display surface of display unit 216. Second detection portion 281 outputs one or more coordinate values input from touch panel 217A to second determination portion 283.
Second determination portion 283 determines whether the position indicated by the coordinate value input from second detection portion 281 belongs to the second self-operation screen or the first remote operation screen, based on the display information input from second display control portion 255. When two or more coordinate values are input from second detection portion 281, second determination portion 283 detects whether the positions indicated by two or more coordinates values both belong to the second self-operation screen or the first remote operation screen. When the positions indicated by one or more coordinate values input from second detection portion 281 belong to the second self-operation screen, second determination portion 283 determines as the self-operation. When the positions indicated by one or more coordinate values input from second detection portion 281 belong to the first remote operation screen, second determination portion 283 determines as a remote operation.
When it is determined as the self-operation, second determination portion 283 converts one or more coordinate values input from second detection portion 281 into one or more coordinate values indicating the positions in the second self-operation screen and outputs positional information including the converted one or more coordinate values to second self-operation accepting portion 285. When it is determined as the remote operation, second determination portion 283 converts one or more coordinate values input from second detection portion 281 into one or more coordinate values indicating the positions in the first remote operation screen and outputs positional information including the converted one or more coordinate values to second remote operation accepting portion 287.
Second self-operation accepting portion 285 includes a second setting accepting portion 291, a second coordination instruction accepting portion 293, and a second copy instruction accepting portion 295. Second setting accepting portion 291 accepts an operation by the user based on the second self-operation screen specified by the display information input from second display control portion 255 and the positional information input from second determination portion 283. The operation by the user is determined by the second self-operation screen specified by the display information input from second display control portion 255.
Second coordination instruction accepting portion 293 accepts the user's operation of selecting one of portable information 200 and MFP 100 as a client in a state in which a coordination setting screen similar to that shown in
Second copy instruction accepting portion 295 accepts an operation of designating a character string included in the second self-operation screen and outputs the designated character string to second temporary storage portion 289. Second temporary storage portion 289 temporarily stores the character string input from second copy instruction accepting portion 295 into a buffer. Second copy instruction accepting portion 295 accepts a copy instruction when the same positional information is continuously input from second determination portion 283 for a prescribed time T2 or longer. A copy instruction may be accepted when a time period during which the same positional information is input from second determination portion 283 is equal to or shorter than a prescribed time. A copy instruction may be accepted when a predetermined key provided in operation unit 217 is designated.
Second remote operation accepting portion 287 outputs the positional information input from second determination portion 283 to second client portion 261. Second remote operation accepting portion 287 includes a second output portion 297, a second paste position accepting portion 299, and a specific operation detection portion 231.
Second paste position accepting portion 299 accepts the position specified by the positional information input from second determination portion 283 as a paste position if a character string is stored in the buffer by second temporary storage portion 289. Second paste position accepting portion 299 outputs positional information including the coordinate value of the paste position to second output portion 297.
In response to input of the positional information including the coordinate value of the paste position from second paste position accepting portion 299, second output portion 297 reads out the character string stored by second temporary storage portion 289 from the buffer and outputs a set of the positional information including the coordinate value of the paste position and the character string to second client portion 261. When the set of the positional information and the character string is input, second client portion 261 assumes that the character string is input to the paste position specified by the positional information in the first remote operation screen. Specifically, the character string and the positional information are transmitted to MFP 100 functioning as a server. Accordingly, the character string included in the second self-operation screen displayed on display unit 216 can be input to the paste position in the first remote operation screen displayed on display unit 216.
Specific operation detection portion 231 detects a specific operation when the positional information input from second determination portion 283 indicates two or more positions in the first remote operation screen. Two or more coordinate values included in the positional information input from second determination portion 283 indicate two or more positions designated by the user on touch panel 217A. Specific operation detection portion 231 receives a plurality of coordinate values corresponding to a plurality of positions simultaneously designated from touch panel 217A.
Specific operation detection portion 231 detects a specific operation by the user based on a temporal change of two or more coordinate values included in the positional information input from second determination portion 283, and also detects the amount of change. The specific operation includes an enlargement operation and a reduction operation. The enlargement operation is an operation of designating the display surface of display unit 216 simultaneously with two fingers and widening the distance between two positions designated with the two fingers. This operation is called a pinch-out operation. Conversely, the reduction operation is an operation of designating the display surface of display unit 216 simultaneously with two fingers and narrowing the distance between two positions designated with the two fingers. This operation is called a pinch-in operation.
Specific operation detection portion 231 detects the enlargement operation or the reduction operation based on a change in distance between two coordinates specified by two or more coordinate values included in the positional information input from second determination portion 283, and also detects the amount of change. A change amount D is obtained from a first distance L1 between two coordinates at a first time and a distance L2 between two coordinates at a second time later than the first time. The change amount D is a value obtained by subtracting distance L1 from distance L2. If the change amount D is positive, it is the enlargement operation, and if a negative value, it is the reduction operation. For example, the first time may be the initial time when two coordinate values are simultaneously input from touch panel 217A, and the second time may be the time when the distance between coordinates of two coordinate values simultaneously input from touch panel 217A stops being changed.
The enlargement operation and the reduction operation are not limited to the pinch-out operation and the pinch-in operation and may be an operation of designating with three or more fingers. For example, the enlargement operation may be an operation of designating simultaneously with three or more fingers and widening the distance between two positions designated with two fingers at opposite ends of the three or more fingers, and the reduction operation may be an operation of narrowing.
When the specific operation is detected, specific operation detection portion 231 selects any one of two or more coordinate values included in the positional information input from second determination portion 283 and converts the selected coordinate value into a coordinate value indicating the position in the first remote operation screen. Specific operation detection portion 231 outputs a set of the converted coordinate value and the detected change amount D to specific operation transmission portion 275. When detecting the specific operation, specific operation detection portion 231 selects any one of two or more coordinate values included in the positional information initially input from second determination portion 283.
Specific operation transmission portion 275 transmits specific operation information including the set of the coordinate value and the change amount input from specific operation detection portion 231 to MFP 100 through wireless LAN I/F 218.
As described above, while portable information apparatus 200 functions as a server, in response to input of a predetermined second specific operation screen from second operation screen determination portion 253, second alternative screen transmission portion 267 outputs the predetermined second alternative screen corresponding to the second specific operation screen, in place of the second specific operation screen, to second server portion 259, outputs the second specific operation screen to second display control portion 255, and outputs a drive instruction to second switch portion 265. The second specific operation screen is, for example, a screen that prompts for an operation on portable information apparatus 200 functioning as a server. For example, the screen prompts for an operation of inserting a connector of a charger to a socket for charging portable information apparatus 200.
Thus, second server portion 259 transmits the second alternative screen to MFP 100 functioning as a client, so that MFP 100 displays the second alternative screen without displaying the second specific operation screen. When a drive instruction is input from second alternative screen transmission portion 267 to second switch portion 265, the second specific operation screen is output to second display control portion 255. In order to allow display unit 216 to display the second specific operation screen, second switch portion 265 switches the operation mode of display unit 216 to the normal mode.
Second self-operation screen 323 is a screen for displaying the address data of the user named “Ishikawa” registered in an address book. Here, the name, company name, postal address, email address, telephone number, and facsimile number of the user named “Ishikawa” are displayed.
First remote operation screen 325 is a registration screen for registration in an address book. First remote operation screen 325 includes regions for inputting name, company name, email address, and facsimile number as address data.
The character string of the name displayed in second self-operation screen 323 is copied, and the region for inputting a name in first remote operation screen 325 is designated. Then, the copied character string of the name is entered in the region for inputting a name in first remote operation screen 325. Similarly, for the company name, email address, and facsimile number, the character string displayed in second self-operation screen 323 is copied, and the corresponding region in first remote operation screen 325 is designated. Then, the copied character string is entered in the input region included in first remote operation screen 325.
First remote operation screen 335 includes a preview image 337. The user performs a pinch-out operation of designating preview image 337 with the two fingers and widening the distance between the two fingers, so that an enlargement operation is input as a specific operation. The specific operation information is then transmitted to MFP 100. Accordingly, MFP 100 transmits a new first remote operation screen including the enlarged image of preview image 337. Thus, first remote operation screen 335 switches to a new first remote operation screen including the enlarged image. Therefore, MFP 100 can be remotely operated with a specific operation that can be input to portable information apparatus 200 but cannot be input to MFP 100.
First remote operation screen 345 is the first alternative screen. Here, the first alternative screen includes a message “See the operation screen on the MFP main unit for the procedure 6 of MFP operation.” Therefore, when operating portable information apparatus 200, the user can be prompted to see display unit 161 of MFP 100.
Second remote operation screen 365 is the second alternative screen. Here, the second alternative screen includes a message “Caution!! See the operation screen of the portable information apparatus ASAP!!” Therefore, when operating MFP 100, the user can be prompted to see display unit 216 of portable information apparatus 200.
In step S02, it is determined whether it is possible to coordinate with portable information apparatus 200. The network address of portable information apparatus 200 as the other party to coordinate with is stored beforehand. A coordination request for asking portable information apparatus 200 whether coordination is possible is transmitted using the network address. If a permission signal is returned from portable information apparatus 200, it is determined that coordination is possible. If coordination is possible, the process proceeds to step S03. If not, the process ends. In this case, for example, a message may be displayed on display unit 161 to notify the user that coordination is impossible.
Network addresses of a plurality of portable information apparatuses that can be coordinated may be stored beforehand. A list of the respective apparatus identification information of a plurality of portable information apparatuses may be displayed so that it is determined whether it is possible to communicate with the portable information apparatus of the apparatus identification information selected by the user. Alternatively, an inquiry signal may be transmitted by broadcast to search for communicable portable information apparatuses. Then, a list of apparatus identification information of one or more communicable portable information apparatuses detected by the search may be displayed so that the portable information apparatus of the apparatus identification information selected by the user is specified as an apparatus that can be coordinated.
In step S03, the operating apparatus is decided. The process then proceeds to step S04. Of portable information apparatus 200 and MFP 100, the apparatus designated by the user is decided as the operating apparatus serving as a client. Specifically, the coordination setting screen shown in
In step S04, portable information apparatus 200 to coordinate with is notified of the operating apparatus. The process then proceeds to step S08. Specifically, operating apparatus information including the apparatus identification information of the operating apparatus decided in step S03 is transmitted to portable information apparatus 200 through communication I/F unit 112.
On the other hand, in step S05, it is determined whether a coordination request is received. If communication I/F unit 112 externally receives a coordination request, the process proceeds to step S06. If not, the process returns to step S01. In step S06, the apparatus that has transmitted the coordination request is specified, and a permission signal indicating that coordination is possible is returned to the specified apparatus. In the next step S07, it is determined whether the operating apparatus information is received. For example, if a coordination request is received from portable information apparatus 200, the user of portable information apparatus 200 decides which of portable information apparatus 200 and MFP 100 is to be set as the operating apparatus. Portable information apparatus 200 transmits the operating apparatus information including the apparatus identification information for identifying the operating apparatus decided by the user. CPU 111 controls communication I/F unit 112 to receive the operating apparatus information from portable information apparatus 200. The process waits until the operating apparatus information is received. If the operating apparatus information is received, the process proceeds to step S08.
In step S08, it is determined whether the MFP itself is the operating apparatus. If the MFP itself is the operating apparatus, the process proceeds to step S09. If not, the process proceeds to step S16. In step S09, a client task is activated. Specifically, a client program stored in ROM 113, EEPROM 115, HDD 116, or CD-ROM 119A is executed. In doing so, the network address of portable information apparatus 200 serving as a server, for example, the IP (Internet Protocol) address is passed as an argument to the client task. At this stage, the client task receives the second remote operation screen from portable information apparatus 200.
In the next step S10, the respective display regions of the first self-operation screen and the second remote operation screen are determined. The display regions in the display surface of display unit 161 are determined. The first self-operation screen is an operation screen for operating MFP 100. The second remote operation screen is an operation screen received by the client task from portable information apparatus 200 for remotely operating portable information apparatus 200. In step S11, the display region determined for the first self-operation screen in step S10 is set as a region for displaying the first self-operation screen. In step S12, the display region determined for the second remote operation screen in step S10 is set as a region for displaying the second remote operation screen output by the client task activated in step S09.
In the next step S13, a first operation accepting process is executed. The process then proceeds to step S14. The details of the first operation accepting process will be described later. In step S14, it is determined whether a coordination end instruction is accepted. The coordination end instruction is accepted if the user designates a key in operation unit 163 to which a coordination end instruction is allocated. Alternatively, the coordination end instruction is accepted when communication I/F unit 112 receives a coordination end signal from portable information apparatus 200. If the coordination end instruction is accepted, the process proceeds to step S15. If not, the process returns to step S13. In step S15, the display region of the first self-operation screen is set in the entire region of the display surface of display unit 161. The process then ends.
On the other hand, in step S16, a server task is activated. Specifically, a server program stored in ROM 113, EEPROM 115, HDD 116, or CD-ROM 119A is executed. At this stage, the server task communicates with portable information apparatus 200 serving as a client, transmits the first self-operation screen as the first remote operation screen to portable information apparatus 200, and executes a process in accordance with the operation received from portable information apparatus 200.
In the next step S17, it is determined whether an operating user is present. It is determined whether the user who operates operation unit 163 is present. If there exists a user who operates operation unit 163 to log into MFP 100, it is determined that an operating user is present. If no operating user is present, the process proceeds to step S18. If an operating user is present, step S18 is skipped, and the process proceeds to step S19. In step S18, driving of display unit 161 is stopped. Here, electric power supplied to display unit 161 is cut off. This is to prevent display unit 161 from consuming power and to reduce power consumption. In place of cutting off electric power, power consumed by display unit 161 may be reduced. If an operating user is present, step S18 is not executed, so that the first self-operation screen appears on the entire screen of display unit 161. This allows the operating user to perform an operation in accordance with the first self-operation screen.
In the next step S19, it is determined whether transmission of the first specific operation screen is detected. The first remote operation screen transmitted to portable information apparatus 200 by the server task activated in step S16 is monitored, and it is determined whether the transmitted first remote operation screen is the first specific operation screen. If transmission of the first specific operation screen is detected, the process proceeds to step S20. If not, the process proceeds to step S23.
In step S20, display unit 161 that is stopped being driven in step S18 is driven. In the next step S21, the first specific operation screen is displayed on display unit 161. The process then proceeds to step S22. In step S22, the first alternative screen is transmitted to portable information apparatus 200. The process then proceeds to step S27. When the server task transmits the first specific operation screen, transmission of the first specific operation screen is stopped before the first specific operation screen is transmitted, and the first alternative screen is transmitted to portable information apparatus 200, in place of the first specific operation screen. Accordingly, at portable information apparatus 200, the first specific operation screen is not displayed but the first alternative screen is displayed.
On the other hand, in step S23, it is determined whether the specific operation information is received. It is determined whether communication I/F unit 112 receives the specific operation information from portable information apparatus 200. If the specific operation information is received, the process proceeds to step S24. If not, the process proceeds to step S27. The specific operation information includes positional information indicating a position in the first self-operation screen transmitted as the first remote operation screen by the server task, and the amount of change.
In step S24, the operation is specified based on the specific operation information. Specifically, of operations that can be input to the first self-operation screen, an operation allocated at a position in the first self-operation screen as specified by the positional information included in the specific operation information, or an operation corresponding to an image at a position in the first self-operation screen as specified by the positional information included in the specific operation information, with designation of the amount of change, is specified. For example, when the position in the first self-operation screen as specified by the positional information included in the specific operation information is in an image, an operation of enlarging the image or an operation of reducing is specified. If the amount of change is positive, the operation of enlarging is specified. If the amount of change is negative, the operation of reducing is specified. When the position in the first self-operation screen as specified by the positional information included in the specific operation information is in a region for inputting a parameter, an operation of increasing the parameter or an operation of reducing the parameter is specified.
Then, the process corresponding to the operation specified in step S24 is determined (step S25), and the determined process is executed (step S26). The process then proceeds to step S27. For example, in a case where the first self-operation screen includes an image and the specific operation information includes positional information indicating the position in the image and a positive amount of change, a process of enlarging the image in the first self-operation screen is executed, and the server task transmits the first self-operation screen with the enlarged image as a new first remote operation screen to portable information apparatus 200. This allows the user using portable information apparatus 200 to input an operation of enlarging the image in the first self-operation screen using the operation function included in portable information apparatus 200.
In step S27, it is determined whether a coordination end instruction is accepted. The coordination end instruction is accepted when communication I/F unit 112 receives a coordination end signal from portable information apparatus 200. If the coordination end instruction is accepted, the process proceeds to step S28. If not, the process returns to step S19. In step S28, display unit 161 that is stopped being driven in step S18 is driven. The process then ends.
In step S32, it is determined whether the designated position is in the display region of the first self-operation screen. The display region of the first self-operation screen is a region in the display surface of display unit 161 that is set in step S11 in
In step S33, it is determined whether the designation time during which the designated position is detected is equal to or longer than the threshold value T1. If the designation time is equal to or longer than the threshold value T1, the operation is determined as designating copy, and the process proceeds to step S34. If not, the process proceeds to step S35. In step S34, the character string arranged in the vicinity of the designated position in the first self-operation screen is temporarily stored in the buffer. The process then returns to the image processing apparatus coordination process. A temporal change of the designated position may be detected, and the character string included in the region specified by the changing designated position may be specified as a character string to be temporarily stored. In step S35, the operation corresponding to the designated position is accepted. The process then returns to the image processing apparatus coordination process.
On the other hand, in step S36, it is determined whether the designated position is in the display region of the second remote operation screen. The display region of the second remote operation screen is a region in the display surface of display unit 161 that is set in step S12 in
In step S37, it is determined whether step S34 is executed and a character string is stored in the buffer. If a character string is stored, the operation is determined as designating paste, and the process proceeds to step S38. If not, the process proceeds to step S40. In step S38, the character string is read out from the buffer, and the designated position and the character string are output to the client task. In the client task, it is determined that the character string is entered in the designated position, and the operation in which the character string is entered in the designated position is transmitted to portable information apparatus 200 as a server. Thus, the character string can be entered in the second remote operation screen with a simple operation of copying the character string included in the first self-operation screen and pasting it in the input region in the second remote operation screen. In the next step S39, the buffer is cleared. The process then returns to the image processing apparatus coordination process.
In step S40, the designated position is output to the client task. The process then returns to the image processing apparatus coordination process. The client task transmits the operation of designating the designated position to portable information apparatus 200 as a server. Then, portable information apparatus 200 detects that the designated position in the second self-operation screen that is the second remote operation screen is designated, and accepts a remote operation.
In step S41, it is determined whether a coordination end instruction is accepted. The coordination end instruction is accepted if the designated position is in a region of the key to which an instruction to terminate the coordination process is allocated. If the coordination end instruction is accepted, the process proceeds to step S42. If not, the process returns to the image processing apparatus coordination process. In step S42, a notice of coordination end is given to portable information apparatus 200 as a client. The process then returns to the image processing apparatus coordination process. Specifically, a coordination end signal is transmitted to portable information apparatus 200 through communication I/F unit 112.
On the other hand, in step S105, it is determined whether a coordination request is received. If wireless LAN I/F 218 externally receives a coordination request, the process proceeds to step S106. If not, the process returns to step S101. In step S106, the apparatus that has transmitted the coordination request is specified, and a permission signal indicating coordination is possible is returned to the specified apparatus. The process then proceeds to step S107. In step S107, the process waits until the operating apparatus information is received. If the operating apparatus information is received, the process proceeds to step S108.
In step S108, it is determined whether the portable information apparatus itself is the operating apparatus. If the portable information apparatus itself is the operating apparatus, the process proceeds to step S109. If not, the process proceeds to step S116. In step S109, a client task is activated. At this stage, the client task receives the first remote operation screen from MFP 100.
In the next step S110, the respective display regions of the second self-operation screen and the first remote operation screen are determined. The display regions in the display surface of display unit 216 are determined. The second self-operation screen is an operation screen for operating portable information apparatus 200. The first remote operation screen is an operation screen received by the client task from MFP 100 for remotely operating MFP 100. In step S111, the display region determined for the second self-operation screen in step S110 is set as a region for displaying the second self-operation screen. In step S112, the display region determined for the first remote operation screen in step S110 is set as a region for displaying the first remote operation screen output by the client task activated in step S109.
In the next step S113, a second operation accepting process is executed. The process then proceeds to step S114. The details of the second operation accepting process will be described later. In step S114, it is determined whether a coordination end instruction is accepted. The coordination end instruction is accepted if the user designates a key in operation unit 217 to which a coordination end instruction is allocated. Alternatively, the coordination end instruction is accepted when wireless LAN I/F 218 receives a coordination end signal from MFP 100. If the coordination end instruction is accepted, the process proceeds to step S115. If not, the process returns to step S113. In step S115, the display region of the second self-operation screen is set in the entire region of the display surface of display unit 216. The process then ends.
On the other hand, in step S116, a server task is activated. At this stage, the server task communicates with MFP 100 serving as a client, transmits the second self-operation screen as the second remote operation screen to MFP 100, and executes a process in accordance with the operation received from MFP 100.
In the next step S117, driving of display unit 216 is stopped. Here, electric power supplied to display unit 216 is cut off. This is to prevent display unit 216 from consuming power and to reduce power consumption. In place of cutting off electric power, power consumed by display unit 216 may be reduced. In the next step S118, it is determined whether transmission of the second specific operation screen is detected. The second remote operation screen transmitted to MFP 100 by the server task activated in step S116 is monitored, and it is determined whether the transmitted second remote operation screen is the second specific operation screen. If transmission of the second specific operation screen is detected, the process proceeds to step S119. If not, the process proceeds to step S122.
In step S119, display unit 216 that is stopped being driven in step S117 is driven. In the next step S120, the second specific operation screen is displayed on display unit 216. The process then proceeds to step S121. In step S121, the second alternative screen is transmitted to MFP 100. The process then proceeds to step S122. When the server task transmits the second specific operation screen, transmission of the second specific operation screen is stopped before the second specific operation screen is transmitted, and the second alternative screen is transmitted to MFP 100, in place of the second specific operation screen. Accordingly, at MFP 100, the second specific operation screen is not displayed but the second alternative screen is displayed.
In step S122, it is determined whether a coordination end instruction is accepted. The coordination end instruction is accepted when wireless LAN I/F 218 receives a coordination end signal from MFP 100. If the coordination end instruction is accepted, the process proceeds to step S123. If not, the process returns to step S118. In step S123, display unit 216 that is stopped being driven in step S117 is driven. The process then ends.
In step S132, it is determined whether the designated position is in the display region of the second self-operation screen. The display region of the second self-operation screen is a region in the display surface of display unit 216 that is set in step S111 in
In step S133, it is determined whether the designation time during which the designated position is detected is equal to or longer than the threshold value T2. If the designation time is equal to or longer than the threshold value T2, the operation is determined as designating copy, and the process proceeds to step S134. If not, the process proceeds to step S135. In step S134, the character string arranged in the vicinity of the designated position in the second self-operation screen is temporarily stored in the buffer. The process then returns to the portable information apparatus coordination process. A temporal change of the designated position may be detected, and the character string included in the region specified by the changing designated position may be specified as a character string to be temporarily stored. In step S135, the operation corresponding to the designated position is accepted. The process then returns to the portable information apparatus coordination process.
On the other hand, in step S136, it is determined whether the designated position is in the display region of the first remote operation screen. The display region of the first remote operation screen is a region in the display surface of display unit 216 that is set in step S112 in
In step S137, it is determined whether a specific operation is detected. The specific operation is detected if a plurality of designated positions are detected in step S131. If a specific operation is detected, the process proceeds to step S138. If not, the process proceeds to step S140. In step S138, the amount of change is detected based on a temporal change of a plurality of designated positions detected. The specific operation includes an enlargement operation and a reduction operation. The change amount D is obtained from a distance L1 between two designated positions at a first time and a distance L2 between two designated positions at a second time later than the first time. The change amount D is a value obtained by subtracting distance L1 from distance L2. If the change amount D is positive, the operation is an enlargement operation. If negative, it is a reduction operation. The first time is a time when the designated position is initially detected, and the second time is a time when a designated position is no longer detected or the distance between two designated position stops being changed.
In step S139, the specific operation information is transmitted to MFP 100 through wireless LAN I/F 218. The process then returns to the portable information apparatus coordination process. The specific operation information includes a set of a coordinate value of one of a plurality of designated positions detected in step S131 and the amount of change detected in step S138.
In step S140, it is determined whether step S134 is executed and a character string is stored in the buffer. If a character string is stored, the operation is determined as designating paste, and the process proceeds to step S141. If not, the process proceeds to step S143. In step S141, the character string is read out from the buffer, and the designated position and the character string are output to the client task. In the client task, it is determined that the character string is entered in the designated position, and the operation in which the character string is entered in the designated position is transmitted to MFP 100 as a server. Thus, the character string can be entered in the first remote operation screen with a simple operation of copying the character string included in the second self-operation screen and pasting it in the input region in the first remote operation screen. In the next step S142, the buffer is cleared. The process then returns to the portable information apparatus coordination process.
In step S143, the designated position is output to the client task. The process then returns to the portable information apparatus coordination process. The client task transmits the operation of designating the designated position to MFP 100 as a server. Then, MFP 100 detects that the designated position in the first self-operation screen that is the first remote operation screen is designated, and accepts a remote operation.
In step S144, it is determined whether a coordination end instruction is accepted. The coordination end instruction is accepted if the designated position is in a region of a key to which an instruction to terminate the coordination process is allocated. If the coordination end instruction is accepted, the process proceeds to step S145. If not, the process returns to the portable information apparatus coordination process. In step S145, a notice of coordination end is given to MFP 100 as a client. The process then returns to the portable information apparatus coordination process. Specifically, a coordination end signal is transmitted to MFP 100 through wireless LAN I/F 218.
As described above, MFP 100 functions as an image processing apparatus and can function as a server as well as a client. When MFP 100 functions as a server, display unit 161 is switched to the power saving mode, thereby reducing power consumption when functioning as a server. When MFP 100 functions as a client, the first self-operation screen and the second remote operation screen are simultaneously displayed on display unit 161. Therefore, when functioning as a client, MFP 100 can operate itself and portable information apparatus 200.
MFP 100 selects one of the first state in which first server portion 59, which is a task executing the server program, can communicate with portable information apparatus 200 and the second state in which first client portion 61, which is a task executing the client program, can communicate with portable information apparatus 200. This allows one of MFP 100 and portable information apparatus 200 to function as a server and allows the other to function as a client.
When functioning as a client, MFP 100 temporarily stores a character string included in the first self-operation screen and outputs the temporarily stored character string and the positional information indicating the position designated by the user in the second remote operation screen to first client portion 61. Therefore, when MFP 100 functions as a client, the character string included in the first self-operation screen can be entered in the position designated by the user in the second remote operation screen.
When functioning as a server, MFP 100 determines a process for the specific operation based on the specific operation information and the second remote operation screen, in response to reception of the specific operation information including the positional information indicating the position in the remote operation screen transmitted to portable information apparatus 200 functioning as a client, and the amount of change, from portable information apparatus 200, and executes the determined process. Therefore, even when a specific operation different from an operation that can be input to MFP 100 is input to portable information apparatus 200, the specific operation can be transformed into an operation that can be input to MFP 100. As a result, the function of portable information apparatus 200 can be effectively utilized.
When MFP 100 functions as a server, if the first remote operation screen to be transmitted to portable information apparatus 200 functioning as a client is a predetermined first specific screen, MFP 100 transmits another first alternative screen in place of the first remote operation screen, switches display unit 161 to the normal mode, and displays the first remote operation screen on display unit 161. Therefore, when functioning as a server, MFP 100 displays the first specific screen and allows portable information apparatus 200 to display the first alternative screen. As a result, the user can be notified that the user is requested to operate MFP 100.
On the other hand, portable information apparatus 200 can function as a server as well as a client. When portable information apparatus 200 functions as a server, display unit 216 is switched to the power saving mode, thereby reducing power consumption when functioning as a server. When functioning as a client, the second self-operation screen and the first remote operation screen are simultaneously displayed on display unit 216. Therefore, when functioning as a client, portable information apparatus 200 can operate itself and MFP 100.
Portable information apparatus 200 selects one of the first state in which second server portion 259 executing the server program can communicate with MFP 100 and the second state in which second client portion 261 executing the client program can communicate with MFP 100. This allows one of MFP 100 and portable information apparatus 200 to function as a server and allows the other to function as a client.
When functioning as a client, portable information apparatus 200 temporarily stores a character string included in the second self-operation screen and outputs the temporarily stored character string and the positional information indicating the position designated by the user in the first remote operation screen to second client portion 261. Therefore, when portable information apparatus 200 functions as a client, the character string included in the second self-operation screen can be entered in the position designated by the user in the first remote operation screen.
When portable information apparatus 200 functions as a server, if the second remote operation screen is a second specific screen, portable information apparatus 200 transmits another second alternative screen in place of the second remote operation screen and displays the second remote operation screen on display unit 216. Therefore, when functioning as a server, portable information apparatus 200 displays the second specific screen and allows MFP 100 to display the second alternative screen. As a result, the user can be notified that the user is requested to operate portable information apparatus 200.
Image processing system 1 has been described in the foregoing embodiment. However, it is needless to say that the present invention can be understood as an image processing apparatus coordination method allowing each of MFPs 100, 100A, and 100B to execute the image processing apparatus coordination process shown in
Although the present invention has been described and illustrated in detail, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation, the spirit and scope of the present invention being limited only by the terms of the appended claims.
