Exemplary embodiments of the present invention are explained in detail below referring to the accompanying drawings.
A first embodiment of the present invention is explained referring to
The system control unit 16 is connected to the respective units and controls the MFP 10. For example, the system control unit 16 provides the scanner 11 with scanning area information appropriate for a selected sheet size. This system control unit 16 includes a central processing unit (CPU), a read only memory (ROM), and a random access memory (RAM). The CPU operates while using a work area of the RAM based on a computer program stored in the ROM, whereby various kinds of processing are performed.
The computer program executed in the MFP 10 can be stored in a computer readable recording medium such as a compact disk-read only memory (CD-ROM), a flexible disk (FD), a compact disk-recordable (CD-R), or a digital versatile disk (DVD) as a file of an installable format or an executable format. In this case, the CPU of the system control unit 16 loads the computer program from the recording medium into a main storage (not shown) to execute it, whereby various functions of the MFP 10 can be realized. The computer program can be stored in a computer connected to the network 18 such as the Internet, and downloaded through the network. the computer program can also be distributed through the network 18.
The communication control unit 17 is connected to the network such as a local area network (LAN) or the Internet and exchanges image data, control data, and the like with other apparatuses connected to the network according to a communication protocol.
The scanner controller 112 receives a command from the system control unit 16 and controls the scanner 11.
The scanner 11 is controlled by the scanner controller 112 and converts an image of the original 19 into digital image data. The ADF 111 sequentially delivers a plurality of pages of originals set thereon to a scanning position of the scanner 11 one by one. Thus, the scanner 11 can automatically and sequentially scan the originals. The ADF 111 can deliver not only an original printed on one side thereof but also an original printed on both sides thereof by reversing the original. Thus, it is possible to cause the scanner 11 to scan the both sides of original.
The image storing unit 12 is a buffer memory that receives a command from the system control unit 16 and temporarily stores therein image data scanned by the scanner 11, image data input from the outside through the network 18, and the like. The MFP 10 can process image data input from the outside through the network 18 as well as image data scanned by the scanner 11 to form an image.
The image processing unit 13 receives a command from the system control unit 16, applies γ correction, modulation transfer function (MTF) correction, and the like to multi-value data sent from the scanner 11 and temporarily stored in the image storing unit 12. The image processing unit 13 performs gradation processing such as slicing and dithering on the data, and digitalizes (multi-value) the data. The image processing unit 13 performs various kinds of image processing (reduce/enlarge, adjustment of density and colors, etc.) corresponding to functions set by a user, image-area edit (area erasure, area movement, area reversal, etc.), and layout processing (duplex/simplex printing, image combining, margin adjustment, etc.). Thus, the image processing unit 13 creates a preview image indicating a finished state of an image.
The image processing unit 13 includes a preview creating unit 131, a screen information generating unit 132, and a setting unit 133.
Basically, the preview creating unit 131 creates a preview of the original image (a preview image) based on settings or parameters specified for processing image data obtained by pre-scanning an original image and displayed on a display panel 15b. Namely, the preview creating unit 131 creates a preview image indicating a results of processing an original image. The preview creating unit 131 uses the multi-value data temporarily stored in the image storing unit 12.
The screen information generating unit 132 generates input screen information displayed on the display panel 15b. The input screen information includes various types of setting items for the preview image created by the preview creating unit 131.
When the user provides setting input on an input screen 400 displayed on the display panel 15b through a touch panel 15a, described later, the setting unit 133 receives a signal of the setting input and acquires coordinate information concerning an input image stored in the image storing unit 12.
When the setting unit 133 receives a setting-input signal, the preview creating unit 131 updates the preview image according to the setting-input signal. The preview creating unit 131 displays the update preview image.
The screen information generating unit 132 generates, according to the setting-input signal received by the setting unit 133, input screen information for display of a screen for receiving setting input from the user again. The display panel 15b updates and displays the input screen 400 according to the input screen information.
The printer controller 142 receives a command from the system control unit 16 and controls the printer 14.
The printer 14 is mounted with the finishing unit 141. The finishing unit 141 performs finishing, based on automatic setting or setting specified by the user, such as sorting, by a unit of the number of copies or a page, a print 20 obtained by printing, stamping a predetermined stamp on a print medium, aligning a plurality of print media and stapling the print media, and punching punch holes for binding the print media in a binder or a file.
The display control unit 151 receives a command from the system control unit 16 and controls input and output of the display unit 15. For example, the display control unit 151 controls to output data processed by the image processing unit 13 to the touch panel 15a and the display panel 15b. More specifically, the display control unit 151 causes the display panel 15b to display a preview image. The display control unit 151 controls input from the touch panel 15a. The display panel 15b and the touch panel 15a are separately shown in
The touch panel 15a detects a position with which a pointer makes an electric or magnetic contact. As pointing means (not shown) for pointing a position on the touch panel 15a, a finger tip, a stylus pen, and other touch input tools (hereinafter, “pointers”) can be used. The user inputs various settings or parameters including print setting by touching the touch panel 15a with such a pointer.
In the first embodiment, an example is explained in which input is provided by touching the touch panel 15a. However, input can be provided in other manners. For example, the display unit 15 can include a hard key (physical key) that a user presses to issue a command such as a print command. As the display panel 15b, a dedicated display device included in the MFP 10 can be used.
The display unit 15 is controlled by the display control unit 151, receives input of setting details via the touch panel 15a, and displays a preview image and setting items for specifying settings as to the preview image on the display panel 15b.
The display unit 15 displays functions available in the MFP 10 as setting items and receives from the user setting input indicating a setting item selected from the setting items. When a user touches with the pointer a position on the touch panel 15a, a coordinate of the position is detected. When the position is in an area corresponding to an setting item (where the setting item is selectable), the display control unit 151 determines that the setting item is selected. For example, the display unit 15 receives setting of scanning conditions for the scanner 11 corresponding to the state of an original, setting for the image processing unit 13 that performs processing such as image quality adjustment on scanned image data, setting of print conditions for the printer 14, and setting for the finishing unit 141 that applies finishing such as sorting, stapling, and punching to a print after printing.
Upon receiving a setting as described above via the display control unit 151, the system control unit 16 causes the image processing unit 13 to create a preview image by reflecting the setting on the original image data stored in the image storing unit 12. The system control unit 16 sends the preview image to the display unit 15 such that the display unit 15 displays the preview image.
When the user touches the touch panel 15a with the pointer while viewing the preview image 401 displayed on the display panel 15b, the touch panel 15a receives input of positional information concerning a spatial position on a print in a finished state displayed as the preview image 401. In such a case, the setting unit 133 analyzes the positional information received through the touch panel 15a and acquires coordinate information on an image with which the pointer comes into contact.
With such a structure, the MFP 10 displays, prior to actual copy printing, the preview image 401 on the display panel 15b. After checking the preview image 401 visually, the user can change the setting when necessary and perform actual printing.
More specifically, it is possible to perform copying reliably according to a series of processes: (1) pre-scanning an original, (2) displaying an image of the original pre-scanned on a screen as a preview image, (3) when a user touches a predetermined position on the preview image, displaying a menu of functions corresponding to the position, (4) when the user selects one of the functions, immediately reflecting the function in the preview image, and, (5) after checking the update preview image on the screen, starting printing.
As shown in
When the display unit 15 detects a touch on the punch 403 displayed thereon, the system control unit 16 receives setting of the punch 403 via the display control unit 151. The screen information generating unit 132 reads out an area corresponding to the punch 403 from an association table. In the association table, as shown in
The user provides touch input by touching the punch hole area 404 shown in
Although not shown, when the user touches a specific position on the preview image, a menu of functions related to the position can be displayed, such that when a user selects one of the functions, the function can be immediately reflected in the preview image.
In addition, the MFP 10 is also capable of printing an image based on the last or previous preview image and the last or previous settings without pre-scanning.
Preview-edit process according to the first embodiment is explained referring to
When the “No” button B2 is selected via the touch panel 15a, the CPU judges that the last setting is not restored (No at step S1), and printing is performed in a conventional manner. In other words, the CPU displays a screen 600 shown in
On the other hand, when the “Yes” button B1 is selected via the touch panel 15a, the CPU judges that the last setting is restored (Yes at step S1) and displays the last preview image (an image scanned last time) 700 as shown in
The user checks the preview image on the screen, and printing starts according to user's operation of a start key (not shown) on the display unit 15. When the printing is started (Yes at step S7), the CPU saves and stores the preview image displayed on the display panel 15b in the image storing unit 12 (step S8). The preview image saved at step S8 is displayed on the display panel 15b when the setting is required to be restored in the next preview-edit process.
When the user does not start printing (No at step S7) and additionally selects one of the setting items 402 via the touch panel 15a (step S4), the CPU performs the process at steps S5 and S6 again.
After saving the update preview image, when the original image to be printed is not present in the MFP 10 (No at step S9), the CPU causes the scanner 11 to scan the original image (step S10), and causes the printer 14 to print the original image (step S11). On the other hand, when the original image to be printed is present in the MFP 10 (Yes at step S9), the CPU causes the printer 14 to print the original image already scanned by the scanner 11 (step S11).
As described above, according to the first embodiment, the preview image displayed on the display unit 15 is saved and stored. The preview image is read out and displayed on the display unit 15, and settings for the preview image is restored if required. That is, history of setting operation by a user is maintained to restore a setting desired by the user. Thus, it is possible to improve operationality of a user interface of the image processing apparatus.
In the above description, upon restoring the last setting in the preview-edit process, the single preview image (the image scanned last time) 700 is displayed on the display panel 15b. However, as shown in
In this way, one preview image is selected from the preview history before pre-scanning, and settings for the preview image is restored. Thus, settings specified, not only most recently, in the past can be restored, and convenience for the user can be improved.
A second embodiment of the present invention is explained referring to
In the first embodiment, a user selects, before pre-scanning, whether the last setting is to be restored to improve convenience of the user. However, when the last setting is restored before pre-scanning for printing, a user may not be able to specify appropriate settings dependent on a characteristic value of an original image. For example, when margin shift is taken into account, margin shift amounts of the last original and the present original are not always the same.
Thus, in the second embodiment, a user selects, after pre-scanning, whether the last setting is to be restored. When the last setting is not restored, usual preview display is performed without restoring the setting. When the setting is restored, a preview reflecting the last setting is displayed.
When the “No” button B2 is selected via the touch panel 15a, the CPU judges that the last setting is not restored (No at step S1), and printing is performed in a conventional manner. In other words, as shown in
On the other hand, when the “Yes” button B1 is selected via the touch panel 15a, the CPU judges that the last setting is restored (Yes at step S1). As shown in
The user checks the preview image on the screen, and printing starts according to user's operation of the start key (not shown) on the display unit 15. When the printing is started (Yes at step S7), the CPU causes the printer 14 to print the original image scanned by the scanner 11 (step S11).
When the user does not start printing (No at step S7) and additionally selects one of the setting items 402 via the touch panel 15a (step S4), the CPU performs the process at steps S5 and S6 again.
As described above, according to the second embodiment, a user is caused to select, after pre-scanning, whether the last setting is to be restored. When the setting is not restored, usual preview display is performed without restoring the setting. When the setting is restored, a preview reflecting the last setting is displayed. This makes it possible to appropriately carry out setting dependent on a characteristic value of an original image.
A third embodiment of the present invention is explained referring to
In the third embodiment, it is possible to arbitrarily select a setting item previously specified. More specifically, a list of items previously specified is displayed and the user selects a setting item from the list. In this way, the user is supported in restoring a desired setting.
According to the third embodiment, setting items displayed in the history window 800 are displayed as a list according to the following manners:
(1) Time
A setting item most recently used is displayed on the top of the list. With such display of setting items according to time, the last operation can be easily reproduced.
(2) The number of Times of Use
A setting item used a largest number of times is displayed on the top of the list. When there are setting items with the same number of times of use, a setting item more recently specified is displayed. With such display of setting items according to the number of times of use, it is possible to easily select a setting item most frequently used in the MFP 10.
(3) Time and the Number of Times of Use
A setting item X most recently used is displayed on the top of the list, and a setting item Y most frequently used is displayed thereafter. When there are setting items with the same number of times of use, a setting item more recently specified is displayed. With such display of setting items according to the number of times of use after a setting item most recently used, it is possible to easily select a setting item most frequently used after the setting item most recently used.
List display in the history window 800 can be changed according to a combination of settings. For example, in the case of full color printing, “punch” is displayed on the top of the list. From the setting items 402 or the history window 800, the user selects a desired function via the touch panel 15a.
As described above, according to the third embodiment, a list of setting items specified in the past is displayed. A user selects a setting item from the list. Thus, it is possible to support the user in restoring a desired setting state.
A fourth embodiment of the present invention is explained referring to
In the fourth embodiment, setting items presently specified for an image to be printed are compared with setting items for previous preview images. A preview image with setting items in high coincidence with those of the image to be printed is displayed to reduce trial and erroneous settings by the user, which enables efficient printing operation.
In the history window 900, setting items presently specified are compared with setting items previously specified. A preview image with setting items in high coincidence with those presently specified are displayed in higher orders (at the left end in
Coincidence of a history (previous preview image) N=(the number of setting items presently specified/the number of setting items of the history N)×(the number of setting items presently specified that coincides with those of the history N/the number of the setting items of the history N)
For example, when the present setting items are A, B, C, and D and the setting items of the history N are A, B, X, Y, and Z, the coincidence is calculated as 0.32 for the history N as follows:
Coincidence of the history N=(4/5)×(2/5)=0.32
As described above, according to the fourth embodiment, a preview with high coincidence of setting items is displayed as shown in
In the first to fourth embodiments, the MFP 10 is explained as an example of the image processing apparatus. However, the same function as the image processing apparatus described above can be implemented by a combination of an image forming apparatus such as a printer and a computer installed with a predetermined computer program. In this case, the printer is connected to the computer, and a central processing unit (CPU) of the computer reads the computer program from a storage device, such as a hard disk (HD), and executes the computer program.

The recording medium 1217 is, for example, an optical, magnetic, or electric recording medium such as a flexible disk, a hard disk, a CD-ROM, a DVD-ROM, an MO, or a PC card. The computer programs are stored in the recording medium 1217 in a data format readable by the CPU 214. The computer programs can be recorded in a recording medium in advance or downloaded via a communication line into a recording medium. The computer programs can also be distributed through a communication line.
The ROM 1223 stores therein various control programs for the CPU 1222. The RAM 1224 is a work area for the control programs and temporarily stores therein print data and print conditions of a print job input from the PC 1201 and the like. The printer engine 1225 performs printing the print data on a transfer sheet. The staple unit 1226 staples sheets on which the print data is printed. The punch unit 1227 opens punch holes in the transfer sheet on which the print data is printed. In other words, the printer 1202 has a duplex printing function, a punch function, a staple function, and the like.

The printer engine 1225 is of an electrophotographic type and prints print data on a transfer sheet. The printer 1202 can employ, besides electrophotographic printing, inkjet printing, sublimation dye transfer printing, silver salt photographic printing, direct thermosensitive recording, and thermofusible transfer printing.
The printer driver 1217c is a software program that can be run without being hindered by other computer programs, hardware of the printer 1202, and a language used in the PC 1201. The printer driver 1217c is used for controlling the printer 1202 and processing output data and the like.
The CPU 1214 creates and displays, according to the printer driver 1217c, a preview image based on print data and print conditions of the print data input from the input unit 1211. The CPU 1214 transfers print data created by the application program 1217b to the printer 1202.
