Display Control Device, Operation Display Device, Image Processing Apparatus, Display Control Method and Tangible Computer-Readable Recording Medium

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a display control device, an operation display device, an image processing apparatus, a display control method and a tangible computer-readable recording medium for displaying information of files stored in a predetermined storing device on a display unit.

2. Description of Related Art

In an image processing apparatus for reading out an image data stored in a storing device, such as a portable recording medium, to print an image, for example, a list in which the thumbnail images or the like of the image data stored in the storing device are listed is displayed on the display unit and the selecting operation for selecting the image data to be printed from the list is received.

Further, in order to select the image to be printed more accurately, the printing apparatus which carries out the following process is disclosed (See Japanese Patent Application Publication No. 2008-207455). In the printing apparatus, in case that the information relating to the image data in which the image cannot be printed or of which the security is required to be unlocked is displayed among the information relating to the image data stored in the portable recording medium, the substitute images indicating that the image cannot be printed or the security of the image data is required to be unlocked are displayed instead of the thumbnail images.

The apparatus disclosed in Japanese Patent Application Publication No. 2008-207455, is a printing apparatus having only the printing function. Therefore, it is only necessary that the display forms of the files are dissimilated according to whether the image can be printed or not.

However, in the apparatus having a plurality of processing modes, such as the copy, the print, the data communication and the like, the processable statuses of each file, which indicate whether the file can be processed or not are different according to the processing modes. Therefore, when the processing mode is changed, the processable status of one file is often changed between before and after changing the processing mode. For example, in case of a video file, the file can be processed in the transmission mode for transmitting the file by attaching it to an electronic mail. However, the video file cannot be processed in the print mode for printing an image on recording paper.

As described above, in the apparatus having a plurality of processing modes, because the processable status of each file is changed according to the selected processing mode, it is required to suitably display the file information so as to respond to the change of the processing mode.

The image processing apparatus 10 communicates with the operation display device 200, the display control device 300 and the information processing apparatus 400 which will be described later, by using the network communication unit 23.

The image reading unit 24 has a function to obtain the image data by optically reading an original. For example, the image reading unit 24 comprises a light source for irradiating the original with light, a line image sensor for reading the original line by line in the width direction of the original by receiving the reflected light from the original, a moving unit for sequentially moving the reading position line by line in the longitudinal direction of the original, an optical system having lenses, mirrors and the like for guiding the reflected light from the original to the line image sensor and focusing the reflected light on the line image sensor, a converting unit for converting an analog image signal outputted from the line image sensor into digital image data, and the like.

The automatic document feeder 16 has a function to convey the original set to the original feed tray from the top page sheet by sheet and pass the original through the reading position of the image reading unit 24. Further, the automatic document feeder 16 has a function to discharge the original to the predetermined discharge position.

The image processing unit 25 carries out the rasterization processing for converting print data into image data, compression/decompression processing of image data and the like, in addition to the processings, such as enlargement/reduction and rotation of the image.

The printer unit 26 has a function to form an image based on image data, on recording paper. In this embodiment, the printer unit 26 is configured as the so-called laser printer for forming an image by the electrophotographic process. The laser printer comprises a conveying device for the recording paper, a photoconductive drum, a charging device, a laser unit, a developing device, a transfer and separation device, a cleaning device and a fixing device. The image may be formed by another system.

The communication terminal unit 27 is an interface unit for detachably connecting a storing memory which is an external device, such as a portable recording medium (external memory). Various types of external memories, such as a USB (Universal Serial Bus) memory, an SD (Secure Digital) card and the like can be connected to the communication terminal unit 27.

The types of processing (processing modes) which can be carried out by the image processing apparatus 10, include a print mode for printing out an image based on the image data obtained by reading an original or printing out an image of the file, a scan mode for reading the original by the image reading unit 24 to transmit image data, a facsimile mode for reading the original by the image reading unit 24 to carry out the facsimile transmission of the image, a box mode for printing out an image based on the image data stored in a box or transmitting the image data stored in a box, and the like.

The scan mode includes the Scan To E-mail mode for transmitting the read image data as an attached file of an electronic mail, the Scan To FTP mode for carrying out the FTP (File Transfer Protocol) transmission of the read image data, the Scan To Box mode for storing the read image data in a box, the Scan To USB mode for storing the read image data in a USB memory connected to the connection terminal unit 27, and the like.

The box mode includes the Box print mode for printing out the file stored in the box, and the Box transmission mode for transmitting the file stored in the box to an external device.

Further, the image processing apparatus 10 has a function to instruct the display unit 22 to display the list of the files stored in the external memory connected to the connection terminal unit 27 or the hard disk drive 15 and to receive the file selection operation from a user, for selecting the file to be processed in various processing modes from the list (referred to as “file information display function”).

For example, in case that the print mode is selected as the processing mode, the file selected from the list of the files stored in the external memory or the hard disk drive 15 is the file to be printed. Incase that the facsimile mode is selected, the file selected from the above list is the file to be transmitted by the facsimile transmission. In case that the scan mode is selected, the file selected from the list of the files as image data obtained by reading the original is attached. In the Box transmission mode, the file selected from the list of the files stored in the box is attached and transmitted.

In each processing mode, the files which can be processed and the files which cannot be processed exist. For example, a moving file having the MPEG (Moving Picture Experts Group) format can be processed in the Scan To E-mail mode and the Box transmission mode, however, cannot be processed in the print mode.

The image processing apparatus 10 has the management table 40 in which whether the file can be processed or not in each processing mode is registered as a list according to each type of files, by storing it in the hard disk drive 15.

FIG. 2 shows an example of the management table 40. In the management table 40, the processing modes 1 to 4 are registered as processing modes and the types A to E are registered as types of files. In the table, “O” indicates that the file can be processed and “X” indicates that the file cannot be processed. The processing modes include the print mode, the scan mode, the facsimile mode and the like, which are described above. The types of files include PDF (Portable Document Format), TIFF (Tagged Image File Format), BMP (Bitmap), JPEG (Joint Photographic Experts Group), MPEG and the like. The above-described processing modes and the above types of files are examples, and the processing modes and the types of files are not limited to the above-described ones.

Next, the operation in which the image processing apparatus 10 instructs the display unit 22 to display the list of the files stored in the storing device, will be explained. In the embodiment, the operation which is carried out when the external memory, such as the USB memory, is connected to the connection terminal unit 27, is explained.

In the embodiment, in case of the files (image data) which can be processed in the processing mode which is currently set, the information of the files is displayed by the preview in which the thumbnail images of the files are used or by the icon view in which the thumbnail images of the files are treated as icon designs (first display form). In case of the files which cannot be processed in the processing mode which is currently set, the simple view in which the attribute information of the files, such as the file name, is displayed by the character information without using the image information, is carried out (second display form).

In the simple view, the information as to whether the file can be processed or not in another processing mode is displayed. In the embodiment, the information as to whether the file can be processed or not in the current processing mode and in the other processing modes is displayed.

Further, in order to set the preview or the icon view for displaying the files which can be processed in the current processing mode, the default value is previously set by the administrator or the like. The set default value is stored in the nonvolatile memory 14 or the like. The display form can be optically switched between the preview and the icon view while the information of the files is displayed. The display data (image data) to be displayed by the preview, the icon view or the simple view are collectively referred to as the file display information.

FIG. 3 shows the operation which is carried out when the CPU 11 of the image processing apparatus 10 instructs the display unit 22 to display the list of the files stored in the external memory connected to the connection terminal unit 27. In this case, before the external memory is connected to the connection terminal unit 27, one processing mode is selected by a user.

When the CPU 11 of the image processing apparatus 10 detects that the external memory is connected to the connection terminal unit 27 (Step S101; Yes), the CPU 11 obtains the information indicating the processing mode which is currently selected (Step S102).

The CPU 11 reads out and obtains the files stored in the external memory connected to the connection terminal unit 27, and stores the files in the hard disk drive 15 (Step S103). Next, the CPU 11 judges whether each file obtained from the external memory can be processed in the current processing mode or not by referring to the management table 40 (Step S104). In this embodiment, the CPU 11 judges whether each file can be processed in all of the processing modes.

The CPU 11 carries out the file display information preparing process on the basis of the judgment result of Step S104 (Step S105). In the file display information preparing process, in case of the files which can be processed in the current processing mode, the file display information for the preview or the icon view is prepared. In case of the files which cannot be processed in the current processing mode, the file display information for the simple view is prepared.

The CPU 11 stores the information of the file (the attribute information, such as the file name), the file display information prepared in Step S105 and the current processing mode so as to correlate them with each other in the hard disk drive 15 with respect to each file obtained from the external memory connected to the connection terminal unit 27. The stored file display information is reused in case that the information of the file is displayed by the same display form.

The CPU 11 instructs the display unit 22 to display the information of each file (Step S107). In detail, the CPU 11 instructs the display unit 22 to display the file selection window including the list of the file information, which will be explained. In the file selection window, by using the file display information prepared in Step S105, the preview or the icon view is carried out for the file which can be processed in the current processing mode. Further, the simple view is carried out for the file which cannot be processed in the current processing mode. That is, when the file to be processed by the image processing apparatus 10 is selected among the stored files, the CPU 11 instructs the display unit 22 to display the information of the stored files.

When the file selection operation for selecting the file from the displayed list is received, and the setting finish operation (the operation of the setting finish button or the start button) for finishing the settings of the process contents and the like for the selected file is received (Step S108; Yes), this process is ended. Then, the image processing apparatus 10 carries out the process for the selected file in accordance with the selected processing mode.

When the setting finish operation is not received (Step S108; No), the CPU 11 checks whether the changing operation for changing the processing mode is received by the operating unit 21 of the image processing apparatus 10 from the user. When the changing operation for the processing mode is not received (Step S109; No), the process returns to Step S108 and continues. When the changing operation is received (Step S109; Yes), the CPU 11 changes the current processing mode to the processing mode which is designated in the changing operation (Step S110). Then, the process returns to Step S104 and continues. That is, when the changing operation for changing the processing mode is received, the CPU 11 checks whether each file can be processed in the changed processing mode and updates the indication of each file (the display form for the information of the file) in the file selection window according to whether the file can be processed or not in the changed processing mode.

FIG. 4 shows the detail of Step S105 (file display information preparing process) shown in FIG. 3. This process is carried out for each file read out from the external memory connected to the connection terminal unit 27.

The CPU 11 checks whether the processable status of each file is changed between before and after changing the processing mode (Step S141). The processable status indicates whether the file can be processed or not. In case that this process is carried out initially after the external memory is connected, the process proceeds by assuming that in Step S141, the processable status of the file is changed between before and after changing the processing mode.

When the processable status of the file is not changed between before and after changing the processing mode (Step S141; No), the file display information stored in Step S106 before changing the processing mode can be used. Therefore, the process is ended without newly preparing the file display information for the preview, the icon view or the simple view. That is, in this case, the CPU 11 diverts the display information of the file, which is used for displaying the information of the file before changing the processing mode, in the changed processing mode.

When the processable status of the file is changed between before and after changing the processing mode (Step S141; Yes), the CPU 11 checks whether the file display information of the file, which is used in the changed processing mode, is already stored or not (Step S142). That is, the CPU 11 checks whether the above file display information is stored in Step S106. For example, in case that the file can be processed in the changed processing mode and the display form is set to the preview, the CPU 11 checks whether the file display information for the preview of the file is already stored.

In case that the file display information of the file, which is used in the changed processing mode, is already stored (Step S142; Yes), the CPU 11 reads out the file display information (Step S151). Then, the process is ended.

In case that the file display information of the file, which is used in the changed processing mode, is not yet stored (Step S142; No), the CPU 11 prepares the new file display information. In detail, the CPU 11 refers the default value for setting the display form to the preview or the icon view (Step S143), and judges the setting contents of the default value (Step S144). The default value is stored in the nonvolatile memory 14. However, the display form selection operation for selecting the preview or the icon view can be received from the user while the file information is displayed.

In case that the preview is set (Step S144; preview), the CPU 11 checks whether the file can be processed in the current processing mode (Step S145). When the file can be processed (Step S145; Yes), the CPU 11 prepares the file display information for the preview, which includes the image information of the file, such as the thumbnail images or the like (Step S146). Then, the process is ended.

When the file cannot be processed in the current processing mode (Step S145; No), the CPU 11 prepares the file display information for the simple view, which does not include the image information of the file (Step S147). Then, the process is ended.

In case that the icon view is set (Step S144; icon view), the CPU 11 checks whether the file can be processed in the current processing mode (Step S148). When the file can be processed (Step S148; Yes), the CPU 11 prepares the file display information for the icon view, which includes the image information of the file, such as the thumbnail images or the like (Step S149). Then, the process is ended.

When the file cannot be processed in the current processing mode (Step S148; No), the CPU 11 prepares the file display information for the simple view, which does not include the image information of the file (Step S150). Then, the process is ended.

In the file display information for the simple view, the information indicating the processable status in each processing mode is included.

Next, various types of the examples of the file selection window in which the list of the files stored in the storing device is displayed are explained.

FIGS. 5A and 5B show the USB memory 50 connected to the connection terminal unit 27 and an example of the file selection window in which the information of the files stored in the USB memory 50 is displayed. In FIGS. 5A and 5B, the current processing mode is the print mode. FIG. 5A shows the files stored in the connected USB memory 50. In the USB memory 50 of FIG. 5A, the PDF format file 51, the MPEG format file 52 and the BMP format file 53 are stored one by one.

FIG. 5B shows the file selection window 70 in which the information of the files stored in the USB memory 50 of FIG. 5A is displayed in the state that the current processing mode is the print mode. In the file selection window 70, the file information display area 71 for displaying the information of the files and the change button area 72 for arranging the selection buttons for changing the window, are provided. In the upper portion of the file selection window 70, the message indicating the explanation and the operation guide relating to this window is displayed. On the lower side of the massage, the file information 61 to 63 of each file 51 to 53 stored in the USB memory 50 is displayed by the preview or the simple view. In detail, because the PDF format file 51 can be processed (can be output) in the print mode, the file information 61 having the preview form is displayed. Because the MPEG format file 52 cannot be processed (cannot be output) in the print mode, the file information 62 having the simple view form is displayed. Because the BMP format file 53 can be processed (can be output) in the print mode, the file information 63 having the preview form is displayed.

Each of the file information 61 and 63 displayed by the preview includes each thumbnail image 61a, 63a of the files and the file name of each file. Each of the thumbnail images 61a and 63a functions as the file selection button for selecting the file to be processed (to be output).

The file information 62 displayed by the simple view includes the character information which does not include the image information. The file information 62 having the simple view form does not function as the file selection button. In the file information 62 having the simple view form, the file name and the data size of the file are included. Further, the information indicating the processable status in the current processing mode and the processable statuses in the other processing modes is included. In case of the file information 62 having the simple view form shown in FIG. 5B, the symbols “X” of “print” and “FAX” indicate that the file cannot be processed in the print mode nor the facsimile mode. The symbol “O” of the mail attachment indicates that the mail attachment can be carried out. The mail attachment can be carried out in the scan mode, the Box transmission mode and the like. The processable status may be indicated by using the specific processing mode name.

In the file selection window 70, the OK button 73 for finally determining the selection of the file and the cancel button 74 for cancelling the selection of the file are provided. In the left lower part of the window, the preview button 75 for switching the display form for the file information to the preview and the icon view button 76 for switching the display form for the file information to the icon view, are provided. In FIG. 5B, the preview button 75 is selected. When the icon view button 76 is pushed, the display form is switched to the icon view.

FIGS. 6A and 6B show the USB memory 50 and the file selection window 70 in case that the processing mode is changed from the situation of FIG. 5B to the transmission (mail forwarding) mode. The switching operation (the processing mode selection operation) for switching the processing mode is received by the processing mode selection button (not shown) provided in the operating unit 21. The USB memory 50 of FIG. 6A is the same as that of FIG. 5A. In the transmission mode, all of the PDF format file 51, the MPEG format file 52 and the BMP format file 53 can be processed. Therefore, the file information of these files is displayed by the preview. In detail, the file information 62 in the file selection window 70 of FIG. 5B is changed to the file information 64 displayed by the preview in the file selection window 70 of FIG. 6B.

As described above, when the processing mode is changed by operating the operating unit 21 by the user, the display form for the file information of each file in the file selection window 70 is changed according to the processable status of each file in the changed processing mode. Thereby, even though the processing mode is changed, the user can easily recognize the processable status of each file in the changed processing mode. Further, because the preview is widely different from the simple view in the display form, it is possible to easily and instantly recognize the processable status in the current processing mode.

In case of the file which cannot be processed in the current processing mode, the information relating to the processable statuses in the other processing modes is displayed. Therefore, it is possible to quickly switch to the processing mode in which the file can be processed. That is, because it is possible to recognize the processable statuses in the other processing modes before switching the processing mode, it is not necessary to confirm the processable status in each processing mode by switching the processing mode in order. Further, the user can directly change the processing mode to the processing mode in which the file can be processed.

FIG. 7 shows an example of the file selection window 80 in case that the file information is displayed by the icon view. When the icon view button 76 is pushed in the file selection window 70 of FIG. 5B, the window is changed to the file selection window 80 of FIG. 7. In the file selection window 80 of FIG. 7, the icon view button 76 is selected. The parts of the file selection window 80, which are the same as those of the file selection window 70 in FIG. 5B are denoted by the same reference numerals and the explanation thereof is omitted.

In FIG. 7, the information of the files stored in the USB memory 50 of FIG. 5A is displayed. Because the PDF format file 51 stored in the USB memory 50 of FIG. 5A can be processed (can be output) in the print mode, the file information 81 having the icon view form is displayed. Because the MPEG format file 52 cannot be processed (cannot be output) in the print mode, the file information 82 having the simple view form is displayed. Because the BMP format file 53 can be processed (can be output) in the print mode, the file information 83 having the icon view form is displayed.
