(Embodiment 1)
Hereinafter, the present invention will be described in detail by way of examples of preferred embodiments of the present invention with reference to the drawings. However, the relative arrangement of components described in this embodiment, the display screen, and the like are not intended to limit the scope of the present invention to them unless otherwise specified.

  FIG. 1 is a block diagram showing a circuit configuration of an image processing apparatus as an embodiment of a display control apparatus. The image processing apparatus 100 according to the present embodiment is an MFP having a scanning function, a printing function, and a card direct function.

  The image processing apparatus 100 includes a CPU 101, a ROM 102, a DRAM 103, a printer engine 104, a card slot 105, a PC I / F 107, an image processor 109, and an operation panel 111, which are connected by a system bus.

  The CPU 101 is a system control unit of the image processing apparatus 100, and controls the entire image processing apparatus 100. The ROM 102 also stores a system control program of the image processing apparatus 100. The CPU 101 executes various operations related to the image processing apparatus 100 based on, for example, a system control program stored in the ROM 102. In this embodiment, the system control program of the CPU 101 is stored in the ROM 102. However, the present invention is not limited to this. The system control program is stored in an external storage medium such as a floppy (registered trademark) disk or CD-ROM. It is also good.

  The DRAM 103 mainly stores image data, and the printer engine 104 prints an image on a recording medium (recording paper) based on the input image data.

  The PC I / F 107 is an interface for connecting the image processing apparatus 100 and the personal computer 108. The personal computer 108 is a host computer capable of changing various setting data of the image processing apparatus 100 and activating various operations via the PC I / F 107.

  The image sensor 110 is a so-called scanner unit. That is, it is an image reading means such as a contact type reading sensor for reading an image on a document table, and converts the read image into image data. The image processor 109 performs various image processing on the image data input from the image sensor 110.

  The operation panel 111 includes a power switch and various hardware keys 112 (not shown), a display unit 113 for displaying an operation status and a state of the image processing apparatus 100, and a touch panel 115 arranged on the display unit 113. have. The operation panel 111 is configured such that when the operator touches the touch panel 115 with an instrument such as a finger or a touch pen, position coordinates touched by the finger or the instrument are detected by the touch panel controller 114 and a touch event occurs. . The touch event generation procedure by the touch panel 115, the detection method of position coordinates, and the operation method will be described later.

  The card slot 105 is an interface for connecting the memory card 106. When the memory card 106 is connected to the image processing apparatus 100, the user can select / view any image from the images stored in the memory card 106 via the touch panel 115 and the display unit 113.

  When instructed to execute printing after passing through various print settings, the image selected by the user is analyzed by the CPU 101 and printed by the printer engine 104. At this time, the DRAM 103 is used as a buffer for print data. Note that only the image selected from the memory card 106 may be captured in the DRAM 103, or all the images may be captured in order to improve the printing speed.

  In the present embodiment, the printer engine 104 and the operation panel 111 can independently perform processing, and can execute a multitask operation of receiving a user operation via the operation panel 111 while executing printing. However, in such a configuration, all the processes are integrated in the CPU 101, and therefore, when the processing capacity of the CPU 101 is exceeded due to the simultaneous execution of a plurality of heavy processes, the process of the simultaneous operation is affected.

  Here, an operation method of the operation panel 111 according to the present embodiment and the touch panel 115 of the operation panel 111 will be described in detail with reference to FIGS. FIG. 2A is a diagram showing an example of an appearance configuration of the operation panel 111 according to the present embodiment. The operation panel 111 includes a home key 201, a back key 202, and a start key 203 as hard keys 112.

  The home key 201 is a key for transitioning to the home screen which is the starting point of all functions. On the home screen, various functions are classified into several categories, each of which is displayed as an icon, and configured so that the user can select a function by touching one of them. .

  The back key 202 is a key for transitioning to the previous screen. The transition of the screen starting from the home screen is stored in the history, and by pressing the back key 202, the history can be traced to transition to the previous screen. Therefore, the return key 202 is invalid on the home screen which is all the starting points.

  The start key 203 is a key for starting an operation of reading an original image by the image sensor 110 and a printing operation by the printer engine 104.

  Although not shown, display objects configured by icons, image images, soft keys, and the like are arranged on the display unit 113 according to predetermined layout information. To each of these display objects, flag information as to whether or not to receive a touch event is added. When a touch event is issued to a display object to which flag information indicating that a touch event is to be received is added, the CPU 101 is notified and processing programmed for each display object is executed. In addition, display objects arranged in the display unit 113 are divided into a plurality of layers (layers) and display is managed, and each layer can be independently subjected to drawing processing. The details of the layer structure will be described later, but the display objects drawn in each layer can be displayed on the display unit 113 in a predetermined order. In a display object overlapping due to the layer structure, a touch event is issued when a touch event is received for the display object disposed in the upper layer.

  FIG. 2B is a schematic view showing how position information is handled on the touch panel 115. As shown in FIG. As shown in FIG. 2B, position coordinates are defined, for example, as positions on a two-dimensional XY coordinate plane with the upper left as an origin. In the present embodiment, the display unit 113 is configured of 640 pixels in the X direction and 480 pixels in the Y direction, and the touch panel 115 has a resolution of 640 in the X direction and a resolution of 480 in the Y direction to match this. have. Hereinafter, “touch” is performed when the CPU 101 determines that the position coordinates at which the touch is detected on the touch panel 115 matches the display position of the object displayed on the display unit 113, and the case where the CPU 101 is determined to be released. Also expressed as "release". Furthermore, when the touched state is maintained, a drag event including position information is issued at regular intervals by a timer not shown, and a release event is issued when the touched state is released. In this manner, instead of specifying the position on the display unit 113 with the mouse as a pointing device, the finger of the operator, a touch pen, or the like is a direct pointing device, and the position on the display unit 113 can be specified.

  With the above configuration, the operation panel 111 of the image processing apparatus 100 can perform instruction input and various setting operations by operating the hard key 112 or the touch panel 115 while watching the display unit 113. In addition, it is possible to confirm the state of the image processing apparatus 100 through the display unit 113.

  Next, a procedure of creating an image list when the memory card 106 is connected to the card slot 105 will be described with reference to FIG. FIG. 11 is a flowchart of an image list creation procedure executed by the CPU 101 when the memory card 106 is connected to the card slot 105. In the present embodiment, the image processing apparatus 100 corresponds to the file system of the FAT format, and the extension of the image file is an effective image file in which only “.jpg” (image compressed in the JPEG format) is valid. Recognize as

  When it is detected that the memory card 106 is connected to the card slot 105 (S1201), one file information of digital data stored in the memory card 106 is read (S1102). The information read as file information includes a file name including an extension, time stamp (file update date and time) information, and the like.

  Next, it is determined whether the read file name is a valid extension, and it is determined whether the file information is valid (S1103). If the file information is invalid, the file information is discarded (S1105). If the file information is valid, the newly read file information is added to the image list, and the image list is updated by rearranging the file information in the order of old time stamp (S1104). In this case, reordering is performed in the order of old time stamps, but the reordering of the image list is not limited to this. For example, reordering of the time stamps may be performed, and based on other file information , The image list may be rearranged.

  Since the image list is stored on the DRAM 103 and the number is limited, it is determined whether the number of file information is the upper limit of the number of lists (S1106). In the case of the upper limit of the number of lists, for example, when 2000 sheets reach 2000 sheets when the upper limit of the list is reached, the image list creation process is ended (S1108). If it is not the upper limit of the number of lists, this image list update is repeated for all files (S1107) to complete the image list (S1108).

  Here, the image list will be described with reference to FIG. FIG. 12 is a view showing the data configuration of the image list stored in the DRAM 103. As shown in FIG. As illustrated in FIG. 12, the image list 1201 includes various information such as a list number 1202, a file name 1203, and a time stamp 1204. A list number 1202 indicates the order of arrangement of the image data in the image list. A file name 1203 is a file name of each image data including path information, and a time stamp 1204 is update date information of each image data. Here, the case of five image data is illustrated.

  The operation method for selecting / viewing an arbitrary image from the images stored in the image list 1201 created from the information of the memory card 106 by operating the display unit 113 and the touch panel 115 using FIGS. Explain to.

  FIG. 3A is a display example in the one-screen display mode in which the image in the memory card 106 is displayed on the display unit 113. The display unit 113 displays the image display unit 301, the image feed keys 302 and 303, the print setting button 304, and the list display button 305 in the one-screen display mode.

  In the case of the one-screen display mode, the image based on the image data selected in the image list 1201 (by default, the image on the latest update date) is decoded by the software processing by the CPU 101, as shown in FIG. It is displayed on the image display unit 301 as shown. In this state, when the start key 203 on the operation panel 111 is pressed, processing is performed via the CPU 101, and the displayed image is printed on the recording medium such as paper by the printer engine 104. There is. In order to view an image other than the image displayed on the image display unit 301, the image feed key 302 or the image feed key 303 arranged on the left and right may be touched. As a result, the image list is forward-fed or reverse-fed, the images are sequentially called, decoded, and displayed on the image display unit 301. In addition, it is configured such that only the image 3011 displayed on the image display unit 301 moves to the left and right according to the detection of the position coordinates by the feed operation of moving the image display unit 301 while touching with the finger 306. FIG. 3B shows a state in which the image displayed on the image display unit 301 is being switched from the original image 3011 to the next image 3012 by the finger 306 of the user. Thus, the image display unit 301 can display an image before or after the image list by the appearance of a new image from the direction opposite to the moving direction of the original image by the operation of the finger 306. It is possible configuration. In other words, virtually, other images are hidden on the left and right of the image 3011 displayed on the image display unit 301.

  When the user touches the print setting key 304, a print setting screen on which various settings relating to printing such as the type (for example, paper type), size, and grade of the recording medium can be displayed.

  Further, when the user touches the list display key 305, the screen is switched from the one-screen display mode to the list display mode, and a plurality of images are simultaneously displayed on the display unit 113. This enables the user to check a plurality of images simultaneously.

  FIG. 4A shows a screen display example of the list display mode of the display unit 113. As shown in FIG. 4A, in this embodiment, in the list display mode, first, a 20-screen display is performed in which a maximum of 20 images are displayed on one screen. The list display mode includes an image display unit 401 that displays 20 images, a print setting button 304, and a number-of-images switching unit 402. When the list display mode is started, a plurality of images stored in the memory card 106 are divided into predetermined positions of frames divided into a predetermined number (20 in the figure) of the image display unit 401 according to the image list. The images (401 (a), 401 (b), etc.) are displayed. As described above, in order to display an image, the image data of the image to be displayed is read from the memory card one by one according to the list, and the image decoding processing is performed according to the size of the frame to be displayed. In the case where the image processing apparatus 100 does not have special hardware for executing decoding processing for display, the CPU 101 is required to load the CPU 101 because the flow of the series of processing is executed by the CPU 101 for the number of displayed sheets. Become.

  In the list display mode, when the number of image lists is larger than the number of displayed sheets, virtually, other images are hidden on the left and right of the image display unit. By moving the finger 306 to the left and right while touching the image display unit 401, only the image in the image display unit 401 moves to the left and right, and the images appear and displayed in the order of the image list.

  When an image is selected, the user touches and releases a specific image (for example, 401 (a)), thereby switching to a one-screen display mode (see FIG. 3A) and designated. An image is displayed on the image display unit 301.

  The print setting button 304 is the same as that shown in FIG.

  By performing a touch operation on the number of images switching unit 402, it is possible to switch the number of displayed images in the list display mode. In the present embodiment, the image number switching unit 402 can perform switching in a plurality of stages, and the number of displayed images in each stage is determined by the position of the number switching switch 403 arranged inside. That is, the image number switching unit 402 is divided into a plurality of portions, and the display size of the image is associated with each portion. Inside the number-of-images switching unit 402, a movable range (not shown) of the number-of-images switching switch 403 can be touched. In the present embodiment, when the user first touches the movable range of the number switch 403, even if the number switch 403 is not touched, the number switch 403 moves to the touched position. It is assumed that switching is performed. Further, the number-of-sheets switching switch 403 can move the specific area (not shown) of the number-of-images switching unit 402 within the specific range by following the left and right according to the touch operation of the user.

  With the above configuration, the desired number of image display switching among the maximum displayable number on one screen of a plurality of stages is set by the touch operation of the image number switching unit 402 or the user operation of moving the number selection switch 403 left and right. Is possible. In the present embodiment, when the number switch 403 is positioned on the left, the number of images is small (6). When the number switch 403 is positioned at the center, the number of images is standard (20) and on the right. It is possible to switch in three steps of many sheets (80 sheets). The display size of one image in the image display unit 401 differs according to the number of images.

  Next, image display at the time of switching the list display mode will be described with reference to FIG. When the number selection switch 403 is touched with a finger in the list display mode shown in FIG. 4A, the display is switched to the display in FIG. 4B. The difference between FIG. 4A and FIG. 4B is only whether the mask object 404 and the image size object 405 are displayed overlapping each other. That is, when the display is switched to the display of FIG. 4B, the mask object 404 and the image size object 405 are newly displayed.

  Here, images and objects displayed on the display unit 113 of FIG. 4B will be described with reference to FIG. FIG. 5 is a diagram showing the display content of the display unit 113 divided into layers. That is, FIG. 5A to FIG. 5D show display contents in each of the divided layers. The image display unit layer shown in FIG. 5A is the lowermost layer, and an image display unit 401 composed of a plurality of images is displayed. The toolbar layer shown in FIG. 5B is a layer on the layer shown in FIG. 5A, and various instruction objects, specifically, button operation units of the image number switching unit 402 and the print setting button 304 include. In the mask object layer shown in FIG. 5C, a transparent mask object 404 is displayed, and an image size object 405 is displayed in the top image size object layer shown in FIG. 5D. Here, the mask object 404 is an object that invalidates the user's operation on the object or the like disposed below this, and the image size object 405 is an object that indicates the size of the image when changing to the instructed number of printed sheets. is there. In the present embodiment, the size of the image is changed according to the number of displayed image data. The image size object 405 visually indicates the display number of image data and the display size to be changed according to the display number.

  By overlapping 5 (a) on the lowermost, 5 (b) on the top, 5 (c) on the top, and 5 (d) on the top, the final image (FIG. ) Is generated. As shown in FIG. 4B, the objects included in the mask object layer and the image size object layer are disposed on the objects included in the image display layer, and are placed on the toolbar layer. Is not placed. Further, since an event by touch operation is issued to an object arranged from the upper layer, a touch event to the object to the toolbar layer in FIG. 5B is issued. Above the image display unit 401 of the image display unit layer of FIG. 5A, a mask object 404 is disposed so as to cover it. Therefore, a touch event is not issued to the image display unit 401. The mask object 404 is transparent, and the user can confirm the display content of the image display unit layer. In the present embodiment, the image size object 405 displayed in the upper layer has a simple configuration including simple lines and rectangles. This makes it possible to relatively reduce the processing load for display. As described above, the display of each layer can be switched independently.

  FIG. 10 is a flowchart of processing executed by the CPU 101 when an instruction to switch the number of images in the image display layer shown in FIG. 5A is issued.

  Although the details will be described later, the CPU 101 starts processing upon receiving a command to switch the number of sheets (S1001). All the images currently displayed are cleared, and in accordance with the instructed number of displayed sheets, initialization processing such as determination of frame information for arranging the images and display image size is performed (S1002).

  Next, image data is read out one by one from the image list, and decoding processing according to the display image size and arrangement processing according to frame information are performed to display one image data at a predetermined position (S1003). Depending on the size of the display image size, it is also possible to perform the decoding process using a thumbnail image defined in the JPEG format.

  It is determined whether or not the series of processes has been completed for the number of displayed images (all images have been completed) (S1004), and when all images have been displayed, the process is ended (S1007).

  If all the images have not been completed, the process advances to step S1005. In S1005, it is determined whether there is an instruction to switch to the next image size (instruction to switch the number of images next). This is because the processing load on the series of image decoding processing (S1003) is heavy, and the user may then issue a next display number switching instruction before the display processing for all the images is finished. If there is no next command for switching the number of images, the process returns to S1003.

  If a command to switch the number of images is issued during the process (S1005), the image decoding display process is temporarily interrupted (S1006), and the process is ended (S1007). In this case, the image number switching process is started again by the next command (S1001).

  As described above, by performing only decoding of an image necessary for display at all times, an effect is realized that the number switching display can be realized with a configuration having a small temporary storage memory such as the DRAM 103 as well as the processing load of the CPU 101.

  The image display sheet number switching operation will be described in detail with reference to FIGS. FIG. 9 shows a flow of an image display switching process executed by the CPU 101 when the sheet number switch 403 is touched in the list display mode of the image processing apparatus 100. Further, the figure is a diagram showing an example of image display in the list display mode.

  In the display state in the list display mode of FIG. 4A, processing is started by touching the number of images switching unit 402 with a finger 306 (S901).

  By the start of the process, the display unit 113 displays the number-of-sheets switching mode shown in FIG. Specifically, in order to indicate that the image selection is invalid, the mask object 404 which has been subjected to a transparent process at a level at which the display image can be recognized is disposed so as to cover the entire image display unit 401. That is, the mask object 404 is displayed on the mask object layer (S902). At the same time, a grid-type image size object 405 composed of lines simply representing the number of images and display size is displayed on the image size object layer (S903). As described above, in the present embodiment, the number of images in the image number switching unit 402 can be changed to a specific image size among a plurality of image sizes depending on the touched position. In accordance with the position touched first, the number switch 403 is moved to switch the display, and an image size object 405 indicating the image size corresponding to the position is displayed.

  Thereafter, the operation on the touch panel 115 is continuously confirmed. Specifically, the change of the touch operation of the image number switching unit 402 is determined (S904).

  When the touch operation of the image number switching unit 402 is moved, the display of the image size object 405 is changed. Specifically, as shown in FIG. 6A, when it is detected that the number of images has been decreased (left direction in the figure from the current center position) without releasing the finger 306 from the number selection switch 403. Thus, the display of the number selection switch 403 moves in a manner to follow the finger 306. At the same time, the image size object 405 corresponding to the stage in the image number switching unit 402 is switched and displayed (S905). In the present embodiment, the image size object 405 is used to visually represent the size of each image when there are six images. The image processing apparatus 100 continuously confirms the change in the touch operation (S904).

  When it is confirmed in S904 that the user has released the finger 306 from the touch panel, the change in display size is confirmed (decided), the image size object 405 is removed from the display screen (S906), and the mask object 404 is also removed. (S907).

  Next, it is determined whether the newly set image size is the same as the previously set image size (S 908). If the image size has been changed, a command to switch the number of images according to the number of displayed sheets after the change is issued (S909). If there is no change, the process ends without issuing an image number switching instruction (S910).

  Here, the case of changing the image display so as to increase the number of images will be described by giving a specific example. For example, when the finger 306 is released from the display state in which the switch is moved to the left six sheets in the state where 20 images are displayed in FIG. 6A, the image size object 405 and the mask object 404 disappear. After that, the image display layer is updated by the image number switching instruction, the current 20 images are deleted, and the display is switched to the image size according to the newly set six images. When all the images are displayed, the display is switched to the six-image display of FIG. 6B.

  In the present embodiment, before changing the image size, the user can confirm the image size after switching by the image size object 405 having a simple configuration. This improves the operability of the user in selecting a desired image size. Further, in the present embodiment, since the image decoding is performed after the display size of the image is determined, the careless image decoding process is not performed, and the load on the CPU 101 is reduced.

  Here, a display example of an image will be described by using a specific example with reference to FIGS. 4, 6 and 7. For example, when the sheet number switch 403 of the image sheet number switching unit 402 is touched from the 20-sheet display state of FIG. 4A, the sheet number switching mode is entered, and the display is switched to FIG. 4B. When the user directly touches the right or left side of the currently displayed number switching switch 403 (center), the display unit 113 moves the display of the number switching switch 403 following the touched position. At the same time, the image size object 405 is also displayed to indicate the number of images according to the touch position. By moving the finger 306 while touching the sheet number switching switch 403 from the display state of FIG. 4B, the processing of S904 and S905 of FIG. 11 is repeated, and the sheet number switching switch 403 with a small display change load and the image size object Only the display of 405 is switched.

  For example, if the finger 306 is moved in the direction with a small number of sheets (left in the figure) while touching the number change switch 403 from the display state of FIG. 4B, the six sheets display of FIG. When the image is moved in the direction of a large number of sheets (right in the figure) to the display of 20 sheets in the center and in FIG. 4B, the display is switched sequentially to the 80-sheet display of FIG.

  When the user directly touches the left side of the image number switching unit 402 from the state of FIG. 4A, the display is switched to the display of the image size object 405 as shown in FIG. 6A. That is, when the number switch 403 is moved from the center to the left, the number switch 304 for the toolbar layer and the object for the image size object layer are switched to the image size for displaying six sheets (see FIG. 6A).

  Thereafter, when the number switch 403 is returned to the original center position without releasing the finger while touching it, only the display of the number switch 403 and the display of the image size object 405 are switched and displayed. That is, when the switch is returned to the original center position without releasing the switch, only the number switching switch 403 and the image size object 405 are redrawn, and the display is switched to the display of FIG. In this state, when the number switch 403 is released, only the object in the upper layer disappears, and the display switches to the 20-sheet display shown in FIG. 4A (return to FIG. 4A). In this case, only the change of drawing of the upper layer with relatively high processing speed is executed during display switching, and the image decoding with relatively low processing speed is not performed, so the load on the CPU 101 is reduced.

  On the other hand, when the number switch 403 is released in the state of FIG. 6 (a), a plurality of thumbnail images decoded by the new image size are displayed by the number of images switch instruction, and finally the display of FIG. Replace. When the number switch 403 is released in the state of FIG. 7 (a), a plurality of thumbnail images (such as 401 (d)) decoded by the new image size are displayed by the number of images switch instruction, and finally FIG. Switch to the) display.

  Here, in the image display switching process, the display switching of the image display unit layer and the display switching of the toolbar layer and the image size object layer can be performed independently of each other. Therefore, in the present embodiment, in the state where the thumbnail image has not been updated yet, the setting is made so that the size can be changed again by the number switching switch. FIG. 8 shows an example in which the change is started again by the number-of-sheets selection switch 403 in the state where the thumbnail image has not been updated yet. FIG. 8A is a display example in which the change is started again by the number-of-sheets selection switch 403 in the state where the update of the thumbnail image in FIG. 7B is not yet completed. In FIG. 8A, the image display unit layer performs image decoding processing sequentially from the upper left image of the image 401 (e) according to the image list, and switches the display in order to display 80 images after switching. At this time, the display on the toolbar layer and the size object layer is switched independently by the operation of the number switch 403 (moving from the right to the center in FIG. 8A). Even during the display switching, the image decoding to the image display unit layer continues sequentially, the image is decoded one by one, and the display is updated. When the number switch 403 is further switched to the left (six sheets), as shown in FIG. 8B, the display of the toolbar layer and the size object layer is switched while the image decoding is continued. Note that when an operation to release the number switch 403 is received at this time, the image decoding to the image display layer is interrupted to switch to the six-image display (described in S1006 of FIG. 10). The image decoding process is started, and the display is switched to the display of FIG.

  In the present embodiment, the display image (the number of displayed images and the display size) after changing the number of displayed images can be confirmed independently of the heavy image decoding and the switching operation of relatively light display units. The load on the CPU 101 is reduced. Further, the user operation procedure becomes simpler than the operation by the hardware button by adopting a configuration in which the number switching instruction by moving the finger 306 of the number switching switch 403 on the touch panel and the determination of the display size by releasing can be made.

That is, in the present embodiment, in the operation of switching the number of displayed images in the image list display mode on the touch panel, image decoding is not performed during the number switching, and only the object showing the number of displayed images after switching (and display size) with small display load. Switch the display of. Then, the image decoding is started with the display size set after the number of displayed sheets is determined. As described above, when switching the number of displayed images based on image data, the processing load is suppressed by visually indicating the number of displayed images and the display size before displaying the images themselves, thereby reducing the number of displayed images to the user. And display size can be easily determined.
