  In addition, in the state where the selection is performed only for a part of the thumbnail images in the continuous range, and the designation of the new arrangement order is accepted only for the part of the thumbnail images, When the “Reflect” soft key is touched, the arrangement order is changed according to the new arrangement order only for the selected thumbnail image, and the arrangement order is changed for the other thumbnail images. Instead, it may be configured to be arranged and displayed after the partial thumbnail image.

  FIG. 10 is an explanatory diagram for explaining another configuration example of the digital multifunction peripheral 1 according to the first embodiment of the present invention. The user selects only “E”, “C”, and “D” thumbnail images in the order of description from among the thumbnail images in the continuous range, and then touches the “Reflect” soft key (FIG. 10A). )). In this case, the position detection unit 81 detects the coordinates of the touch operation position, and based on the detection result, the order changing unit 833 arranges the thumbnail images “E”, “C”, and “D” according to the new arrangement order. The order is changed and the arrangement order is not changed for the other thumbnail images of “B”, “F”, and “G”, and “E”, “C”, “ D ”is displayed after the thumbnail image (FIG. 10B).

  The enlarged display unit 835 enlarges and partially displays the predetermined thumbnail image in the continuous range. FIG. 11 is an explanatory diagram for explaining the operation of the enlarged display unit 835 according to Embodiment 1 of the present invention. For example, in the arrangement order change mode, the user desires to enlarge any thumbnail image among a plurality of thumbnail images displayed in a list because the size of the thumbnail image cannot be confirmed. Touch a thumbnail image for a predetermined time or longer (FIG. 11A). Based on the detection result by the position detection unit 81 and the time measurement result by the time measurement unit, the enlargement display unit 835 enlarges the thumbnail image and displays only the enlargement screen of the thumbnail image when a touch is performed for a predetermined time or more. The image is displayed in a frame of a predetermined size (pixel) in the part 82. In this case, since the image of the enlarged thumbnail image is large, not all of the enlarged images of the enlarged thumbnail image are displayed in the frame, and the enlarged display unit 835 displays a part of the enlarged image of the enlarged thumbnail image. Are displayed in the frame as appropriate.

  For example, when a predetermined part that the user wants to view is not displayed in the frame, the user appropriately slides the fingertip in the direction opposite to the predetermined part (arrow direction) (FIG. 11B). . At this time, the position detection unit 81 detects coordinates on the display screen of the display unit 82 related to the direction, distance, and the like related to the slide of the fingertip, and the enlarged display unit 835 is based on the detection result of the position detection unit 81. A predetermined portion is displayed at the center of the frame (FIG. 11C). That is, the enlarged display unit 835 enlarges and partially displays a predetermined thumbnail image.

  The image generation unit 836 generates a thumbnail image corresponding to an image enlarged by the enlarged display unit 835 (hereinafter, a partially enlarged image) based on the detection result by the position detection unit 81. For example, an operation of sliding a fingertip to visually recognize a predetermined portion desired by the user is performed, and the predetermined portion is displayed at the center of the frame for visual recognition, and then the fingertip is released from the screen of the display unit 82. In the case, the position detector 81 detects it. Based on the detection result of the position detection unit 81, the image generation unit 836 instructs the image processing device 4 to generate a thumbnail image corresponding to the partially enlarged image when the fingertip is released. At this time, the display on the display unit 82 returns to the list display of a plurality of thumbnail images.

  In accordance with an instruction from the image generation unit 836, the thumbnail display unit 837 displays a thumbnail image corresponding to the partially enlarged image generated by the image processing device 4 as a thumbnail image before the enlargement process (the third thumbnail in FIG. 11A). The image is displayed instead of (image) (FIG. 11D).

  The coordinate storage unit 7 stores the coordinates of the contact point of the user's fingertip on the screen of the display unit 82 based on the signal from the position detection unit 81. For example, the coordinates of the touch point when the touch panel 81 is touched, the slide start point when the user performs a so-called slide operation, the coordinates of the contact point, and the like are stored.

FIG. 12 is a flowchart for explaining the process of displaying the partially enlarged image according to the first embodiment of the present invention.
For example, in the list display state of the plurality of thumbnail images in the arrangement order change mode, since the size of the thumbnail image cannot be confirmed, the user enlarges one of the thumbnail images displayed in a list. In this case, a thumbnail image desired to be enlarged is touched for a predetermined time or longer.

  In this case, the CPU of the control unit 2 receives an instruction to enlarge and display the touched thumbnail image based on the detection result by the position detection unit 81 and the time measurement result by the time measurement unit (step S101). The CPU instructs enlargement of the thumbnail image touched on the enlargement display unit 835.

  The enlarged display unit 835 enlarges the touched thumbnail image in accordance with an instruction from the CPU, and displays only the enlarged screen of the thumbnail image within a frame of a predetermined size (pixel) on the display unit 82 (step) S102).

  The CPU monitors the position detection unit 81 and determines whether or not the user has performed a fingertip slide operation based on the detection result (step S103). When the CPU determines that the slide operation is not performed (step S103: NO), the process proceeds to step S105.

  On the other hand, if the CPU determines that a slide operation has been performed (step S103: YES), it instructs the enlargement display unit 835 to give an enlarged image portion (partial enlargement) of the enlarged thumbnail image corresponding to the slide operation. (Image) is displayed (step S104). In response to the instruction from the CPU, the enlarged display unit 835 displays a partially enlarged image within the frame of the display unit 82 based on the detection result of the position detection unit 81. The detailed description relating to the display of the partially enlarged image has been described above, and will be omitted.

  Next, the CPU monitors the position detection unit 81 and determines whether or not the user's fingertip is separated from the screen of the display unit 82 based on the detection result (step S105). When the CPU determines that the fingertip of the user is not separated from the display screen of the display unit 82 based on the detection result by the position detection unit 81 (step S105: NO), the process returns to step S103 again.

  On the other hand, when the CPU determines that the user's fingertip has been separated from the screen of the display unit 82 based on the detection result by the position detection unit 81 (step S105: YES), the CPU instructs the image generation unit 836 to A thumbnail image corresponding to the partially enlarged image displayed when the image is separated is generated (step S106).

  Thereafter, the display on the display unit 82 returns to the list display state of a plurality of thumbnail images, and the thumbnail display unit 837 replaces the thumbnail image corresponding to the partially enlarged image generated in step S106 with the thumbnail image before the enlargement process. Is displayed on the display unit 82 (step S107).

Hereinafter, processing for changing the arrangement order of thumbnail images in Embodiment 1 of the present invention will be described.
FIG. 13 is a flowchart for explaining the processing for changing the arrangement order in the first embodiment of the present invention. For convenience of explanation, a case where the user partially changes the arrangement order of the thumbnail images displayed on the display unit 82 based on the read image data of a plurality of documents and forms an image based on the image data. This will be described as an example.

  First, the user places a plurality of documents on the document table of the image input apparatus 3 and operates the “copy” key of the operation panel 10 to instruct reading of the documents. The CPU of the control unit 2 receives a reading instruction via the operation panel 10 and instructs the image input device 3 to read the image of the original (step S201). The CPU assigns a number to the image data of the original document acquired by the image input device 3 in this way and stores it in the storage unit 9.

  The CPU instructs the image processing apparatus 4 to generate thumbnail images related to the plurality of documents. The thumbnail image generated by the image processing device 4 is associated with the image data and number and stored in the storage unit 9.

  Next, the CPU reads the thumbnail images and numbers stored in the storage unit 9, and displays a list of the thumbnail images on the display unit 82 in a predetermined arrangement order (for example, reading order) (step S202). (See Fig. 4 (a))

  For example, when the user determines that the order of some of the thumbnail images displayed in the list is back and forth, the “change arrangement order” soft key is used to change the arrangement order of these thumbnail images. touch.

  In such a case, the position detection unit 81 detects coordinates related to the touch operation position by the user, and the CPU sets the arrangement order change mode based on the detection result (step S203).

  Thereafter, the user selects two thumbnail images in order to specify the continuous range including the thumbnail images whose arrangement order is to be changed. At this time, the selection receiving unit 831 receives selection of two thumbnail images via the position detection unit 81 (step S204). Such acceptance of selection of two thumbnail images when accepting designation of the continuous range has been described above, and detailed description thereof will be omitted. (See FIGS. 4B and 4C)

  Next, the range determining unit 832 determines a range (continuous range) of thumbnail images whose arrangement order should be changed based on the selection of the two thumbnail images received by the selection receiving unit 831 (step S205). Specifically, in the thumbnail image list, the range determination unit 832 determines the range of the thumbnail image from the thumbnail image related to the selection first received by the selection receiving unit 831 to the thumbnail image related to the selection received next. The continuous range is determined. Further, in this case, the range determining unit 832 displays all thumbnail images in the continuous range with a color to indicate that they are selected thumbnail images (FIG. 4D).

  When the designation of the continuous range is completed, the thumbnail images of the continuous range whose layout order is to be changed are selected by touching in the new layout order desired by the user. At this time, the order determining unit 834 determines the new arrangement order in the continuous range of the selected thumbnail images based on the selection order received by the selection receiving unit 831 (step S206). The determined new arrangement order is stored in the storage unit 9. The process for determining such a new arrangement order has been described above, and a detailed description thereof will be omitted (see FIG. 6).

  Thereafter, for example, the user touches the “Reflect” soft key in FIG. 6 to instruct the change of the arrangement order of the thumbnail images in the continuous range according to the new arrangement order, and the position detection unit 81 performs the touch. Coordinates related to the operation are detected.

  The order changing unit 833 reads the new arrangement order from the storage unit 9 based on the detection result of the position detecting unit 81, and changes the arrangement order of the thumbnail images in the continuous range according to the new arrangement order (step S207). In the example of FIG. 6B described above, when the “Reflect” soft key is touched by the user, the order changing unit 833 changes the arrangement order of the thumbnail images in the continuous range according to the new arrangement order. As shown in FIG. 9, display is performed along the alphabetical order desired by the user. Thereafter, when the user operates the “OK” key, a new number is assigned.

  Next, for example, the CPU receives an instruction to confirm that the image is to be output (printed) in the arrangement order of the thumbnail images after the change. For example, when the user obtains confirmation from the user by operating the “OK” key in the example shown in FIG. 9, the CPU instructs the image output device 5 to display the thumbnail displayed on the display unit 82. An image corresponding to each thumbnail image is formed in the image arrangement order (step S208).

(Embodiment 2)
FIG. 14 is a functional block diagram illustrating a main configuration of the thumbnail display control unit 83 of the digital multi-function peripheral 1 according to the second embodiment of the present invention. The digital multifunction device 1 according to the second embodiment of the present invention has the same configuration as the digital multifunction device 1 according to the first embodiment, but further includes a repeat instruction receiving unit 838.

  The repetition instruction receiving unit 838 receives an instruction to repeatedly perform the same arrangement order change on the remaining thumbnail images as the arrangement order change performed on a part of the thumbnail images in the continuous range. Specifically, when the user performs a specific touch operation only on a part of the thumbnail images in the continuous range, the repeat instruction receiving unit 838 applies to a part of the thumbnail images related to the touch operation. In addition to an instruction to reverse the current arrangement order, the same arrangement order change as the arrangement order change performed for some thumbnail images in the continuous range is performed in the same cycle for the remaining thumbnail images. It is accepted as an instruction to be repeated. When the repeat instruction accepting unit 838 accepts the instruction, the order changing unit 833 changes the arrangement order to reverse the current arrangement order with respect to the partial thumbnail images, and the remaining thumbnail images are changed. Also, the arrangement order change is repeated.

  FIG. 15 is an explanatory diagram for explaining the operation of the repeat instruction receiving unit 838 in the second embodiment of the present invention. For convenience of explanation, a case will be described as an example where the arrangement order of two thumbnail images whose order is before and after is correctly changed. In the example of FIG. 15, the thumbnail images “B” and “C”, “D” and “E”, and “F” and “G” are in reverse order, respectively. And

  Similarly to the description in the first embodiment, when the selection of two thumbnail images is completed, the range determination unit 832 determines the continuous range of thumbnail images whose arrangement order should be changed. For example, the continuous range Are displayed with a color to indicate that they are selected thumbnail images (see FIG. 4D).

  Next, the user selects a part of the continuous range, that is, a range of thumbnail images to be reversed in the continuous range. The user touches the first thumbnail image (“B”) in the range of the thumbnail images to be reversed with one finger (one hand), and maintains the contact state with the other finger (one hand). Then, the last thumbnail image (“C”) in the range of thumbnail images to be reversed is touched (see FIG. 15A). Thereafter, the user performs an operation of rotating the other finger touching the last thumbnail image (“C”) as shown in FIG. 15B while maintaining the contact state.

  When such an operation is performed by the user, based on the selection received by the selection receiving unit 831, the repeat instruction receiving unit 838 selects the current arrangement order of the thumbnail images from the “B” thumbnail image to the “C” thumbnail image. In the reverse order, and the same period is applied to the remaining thumbnail images (that is, thumbnail images of “D”, “E”, “F”, and “G”). It is accepted as a repetitive instruction performed at.

  When the repetition instruction receiving unit 838 receives the repetition instruction, the repetition instruction receiving unit 838 displays the images with different shades of colors attached to all the thumbnail images in the continuous range to indicate that it is a selected thumbnail image (FIG. 15C). reference).

  Next, the user touches the “Reflect” soft key, and the order changing unit 833 arranges the current arrangement order in the reverse order with respect to the partial thumbnail images (thumbnail images “B” and “C”). The remaining thumbnail images (“D”, “E”, “F”, “G” thumbnail images) are also changed in the same cycle (“D”, “E”, and “F”). And “G”) Iteratively changes the arrangement order to reverse the current arrangement order.

  Such a result is shown in FIG. The thumbnail images of “B” and “C”, “D” and “E”, and “F” and “G” are arranged in the arrangement order that reverses the arrangement order before the arrangement order change, respectively, and the display unit 82. You can see that it is displayed.

Hereinafter, processing for changing the arrangement order of thumbnail images in Embodiment 2 of the present invention will be described.
FIG. 16 is a flowchart for explaining the processing for changing the arrangement order in the second embodiment of the present invention. For convenience of explanation, as an example, the user reads the image data of a plurality of documents, changes the arrangement order of the thumbnail images displayed on the display unit 82, and forms an image based on the image data. explain.

  First, the user places a plurality of documents on the document table of the image input apparatus 3 and operates the “copy” key of the operation panel 10 to instruct reading of the documents. The CPU of the control unit 2 receives a reading instruction via the operation panel 10, and instructs the image input apparatus 3 to read the image of the original (step S301). The CPU assigns a number to the image data of the original document acquired by the image input device 3 in this way and stores it in the storage unit 9. The CPU instructs the image processing device 4 to generate thumbnail images related to the plurality of documents, and the thumbnail images generated by the image processing device 4 are associated with the image data and numbers and stored in the storage unit 9.

  Next, the CPU reads out the thumbnail images and numbers stored in the storage unit 9, and displays a list of the thumbnail images on the display unit 82 in a predetermined arrangement order (for example, reading order) (step S302).

  For example, when the user determines that the order of some thumbnail images among the thumbnail images displayed in a list is back and forth and this is repeated, the user can change the arrangement order of the above-mentioned “ Touch the [Change Arrangement Order] soft key. In the following, for convenience of explanation, “B” and “C”, “D” and “E”, “F” and “G” are respectively before and after in the list of thumbnail images as shown in FIG. Shall be allowed to.

  When the user touches the “change arrangement order” soft key, the position detection unit 81 detects coordinates related to the touch operation position by the user, and the CPU sets the arrangement order change mode based on the detection result. (Step S303).

  Thereafter, the user selects two thumbnail images in order to specify the continuous range including the thumbnail images whose arrangement order is to be changed. At this time, the selection receiving unit 831 receives selection of two thumbnail images via the position detection unit 81 (step S304).

  Next, the range determining unit 832 determines a range (continuous range) of thumbnail images whose arrangement order should be changed based on the selection of the two thumbnail images received by the selection receiving unit 831 (step S305). The reception of designation of the continuous range has been described above, and a detailed description thereof will be omitted (see step S205 and FIG. 4D). In this case, the range determination unit 832 colors all the thumbnail images in the continuous range to indicate that the thumbnail image is a selected thumbnail image.

  When the designation of the continuous range is completed, the user selects a part of the continuous range, that is, a range of thumbnail images to be reversed in the continuous range. As described above, the user touches the first thumbnail image in the range of the thumbnail images to be reversed with one finger, and maintains the contact state of the one finger with the other finger. Then, the last thumbnail image in the range of thumbnail images to be reversed is touched (see FIG. 15A). Thereafter, the user performs an operation of rotating the other finger touching the last thumbnail image to draw a circle while maintaining the contact state (see FIG. 15B).

  Further, when reversing the current arrangement order of all the thumbnail images in the continuous range, after selecting the earliest thumbnail image and the last thumbnail image in the continuous range by the method as described above, Rotate your finger to draw a circle on the last thumbnail image. A predetermined key may be provided to reverse the current arrangement order of all thumbnail images in the continuous range.

  When such an operation is performed by the user, the repeat instruction receiving unit 838 displays the current thumbnail image from the earliest thumbnail image to the last thumbnail image based on the selection received by the selection receiving unit 831. In addition to changing the arrangement order to reverse the arrangement order, a repetitive instruction for changing the arrangement order to the remaining thumbnail images in the same cycle is accepted (step S306). At this time, the number of thumbnail images from the earliest thumbnail image to the last thumbnail image, in other words, a cycle in which the arrangement order should be repeatedly changed (hereinafter referred to as a repetition cycle) is selected. Based on the result of selection reception by the reception unit 831, it is stored in the storage unit 9.

  When the repeat instruction accepting unit 838 accepts the repeat instruction, the selection accepting unit 831 recognizes that the selection of all thumbnail images in the continuous range has been accepted, and all the thumbnail images are the colors assigned in step S305. Are displayed in different shades (step S307).

  Next, the user touches the “Reflect” soft key, and the order changing unit 833 changes the arrangement order to reverse the current arrangement order with respect to the thumbnail images from the earliest thumbnail image to the last thumbnail image. For the remaining thumbnail images, based on the repetition period stored in the storage unit 9, the arrangement order change for reversing the current arrangement order is repeated in the same period (step S308). A result is displayed on the display part 82 (refer FIG.15 (d)).

  If the last thumbnail image in the continuous range does not match the repetition period, the arrangement order is changed to reverse the current arrangement order in the continuous range.

  For example, when the user operates the “OK” soft key shown in FIG. 15D, the CPU instructs the image output device 5 to display the thumbnail images in the arrangement order of the thumbnail images displayed on the display unit 82. Is formed on the sheet (step S309).
