For convenience of explanation, a process after receiving position designations at two places via the touch panel 81 will be described as an example.

(1) Finding method 1
First, a case where the number of jump pages is calculated based on the total number of pages in the image set will be described.
For example, when the threshold value is 5 cm and the distance determination unit 832 determines that the distance between the two designated positions detected by the distance detection unit 831 is 5 cm or more, the coefficient setting unit 833 sets the calculation coefficient to 0.5. Set to. On the other hand, when the distance determination unit 832 determines that the distance between the two designated positions is less than 5 cm, the coefficient setting unit 833 sets a numerical value obtained by the following equation as a calculation coefficient.
Calculation coefficient = 0.5 x (distance between two specified positions ÷ 5)

When the calculation coefficient is set as described above, the page number calculation unit 834 calculates the jump page number using the following formula based on the calculation coefficient and the total number of pages of the image set.
Jump page number = calculation coefficient × total number of pages of image set In this calculation result, the decimal point is rounded down and only the integer value is set as the jump page number.

Next, a case where the jump page number is calculated regardless of the total page number of the image set will be described.
When the distance determination unit 832 determines that the distance between the two designated positions detected by the distance detection unit 831 is, for example, 5 cm or more, the page number calculation unit 834 sets the jump page number to 10. On the other hand, when the distance determination unit 832 determines that the distance between the two designated positions is less than 5 cm, the page number calculation unit 834 calculates the jump page number using the following equation.
Number of jump pages = 10 x (distance between two specified positions ÷ 5)
In such a calculation result, the decimal points are rounded down, and only the integer value is set as the jump page number.

(2) Method 2
For example, when a plurality of threshold values (for example, threshold value 1, threshold value 2, threshold value 3) and the distance between two designated positions are less than or equal to threshold value 1 or between threshold value 1 and threshold value 2 in storage unit 9 In addition, the number of jump pages corresponding to each of the cases where the threshold value is 3 or more is stored in advance, and the distance determination unit 832 determines which of the distances of the two designated positions detected by the distance detection unit 831 corresponds to. The page number calculation unit 834 obtains the corresponding jump page number.

  However, the present invention is not limited to this, and a jump page number table in which jump page numbers are associated with each other is stored in advance in the storage unit 9 for each predetermined range of distances between two designated positions. The number of jump pages corresponding to the detected distance between the two designated positions may be determined by the page number calculation unit 834 from the jump page number table. FIG. 4 is an exemplary diagram showing an example of the jump page number table. In the jump page number table of FIG. 4 (a), the number of jump pages based on the total number of pages of the image set is set. In the jump page number table of FIG. 4 (b), the total number of pages of the image set. A fixed value is set without regard to.

  The direction designation accepting unit 835 accepts designation of a direction to jump (hereinafter, jump direction designation) via the touch panel 81. That is, the direction designation receiving unit 835 receives jump direction designation in ascending order or descending order from the page number of the already displayed image. For example, when searching for a predetermined image from the image set, a target page number jumped by the number of jump pages obtained by the page number calculation unit 834 in the jump direction received by the direction designation reception unit 835 is specified, and the target page is specified. Numbered images are displayed as search results.

The reception of the jump direction designation will be described in detail.
The position designation accepting unit 82 accepts via the touch panel 81 by the user's contact operation within the frame of the “page turning” soft key described later displayed on the display unit of the image display device 8 by the frame display unit 836. Based on the position designation, the direction designation accepting unit 835 accepts the jump direction designation. For example, when the user performs a so-called slide operation from the left side to the right side of the “page turning” soft key, the position designation receiving unit 82 specifies the coordinates of the slide start point and the release contact point via the touch panel 81, and When the CPU determines that the coordinate value of the horizontal axis at the contact is larger than the slide start point by a predetermined threshold or more, the direction designation receiving unit 835 accepts the jump direction designation in the ascending direction from the page number of the displayed image. On the other hand, when the user performs a slide operation from the right side to the left side of the “page turn” soft key, the CPU determines that the coordinate value of the horizontal axis at the contact point is smaller than the slide start point by a predetermined threshold value or more. The designation receiving unit 835 receives a jump direction designation in the descending order from the page number of the already displayed image. However, the present invention is not limited to this, and a jump direction designation may be received based on a sliding operation in the vertical (vertical) direction.

  The frame display unit 836 displays a rectangular “page turning” soft key on the display unit of the image display device 8 and receives a page jump execution instruction via the “page turning” soft key. That is, as described above, when the user performs a slide operation from the left side to the right side of the “page turning” soft key, the direction designation receiving unit 835 receives the jump direction designation. At this time, the CPU accepts page jump execution instructions for the number of jump pages calculated by the page number calculation unit 834 in the jump direction.

  The coordinate storage unit 7 stores coordinates relating to the designation of the position received by the position designation receiving unit 82 via the touch panel 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 acquired via the position designation receiving unit 82 and stored.

  Hereinafter, image search by the digital multi-function peripheral 1 according to the first embodiment of the present invention will be described. 5 and 6 are flowcharts showing image search processing by the digital multi-function peripheral 1 according to the first embodiment of the present invention. For convenience of explanation, a case will be described as an example in which the image input device 3 reads 12 document bundles and displays an image related to the document bundle on the display unit of the image display device 8. In other words, an image set having 12 pages in total is displayed on the display unit of the image display device 8. Further, a case where the jump page number is calculated by the above-described obtaining method 1 will be described as an example. The storage unit 9 stores the first page number “1” and the last page number “12” of the image set.

  In order to search for a predetermined image from the image set, the user operates the operation device 10 to select a page jump mode. The CPU receives an instruction to select the page jump mode via the operation device 10 (step S101).

  Next, the CPU instructs the frame display unit 836 to display the “page turning” soft key on the image display device 8 (step S102). The coordinates relating to the rectangular frame forming the “page turning” soft key are stored in the storage unit 9, and the CPU determines whether or not the operation is a contact operation within the frame based on the coordinates of the frame, as will be described later. Judgment is made.

  FIG. 7 is an explanatory diagram for explaining a user's contact operation when searching for a predetermined image from the image set. For example, as shown in FIG. 7, the user presses the touch panel 81 with a fingertip and designates two points, point A and point B. At this time, the position designation receiving unit 82 receives the position designation via the touch panel 81, and the coordinates relating to the received position designation are stored in the coordinate storage unit 7. It is assumed that the distance between the two designated positions of point A and point B is 2 cm. Thereafter, the user performs a sliding operation in a predetermined direction within the frame of the “page turning” soft key, and specifies the jump direction in the ascending or descending direction. The position designation receiving unit 82 further receives the position designation of the slide start point and the release contact via the touch panel 81, and the coordinates of the slide start point and the release contact are stored in the coordinate storage unit 7. FIG. 8 is an explanatory diagram for explaining the sliding operation of the “page turning” soft key by the user.

  When such an operation is performed, the CPU determines whether or not two position designations have been received (step S103). Specifically, the CPU has received two position designations outside the frame of the “page turning” soft key based on the coordinates relating to the position designation received by the position designation receiving unit 82 stored in the storage unit 9. Determine whether or not.

  If the CPU determines that two position designations have not been received (step S103: NO), the CPU instructs the page number calculation unit 834 to set the jump page number to “1” (step S108). In response to an instruction from the CPU, the page number calculation unit 834 sets the jump page number as “1”. That is, the page number jumped by “1” from the page number of the already displayed image is specified as the target page number. Thereafter, the processing moves to step S109.

  On the other hand, when it is determined that the two position designations have been received (step S103: YES), the CPU instructs the distance detection unit 831 to detect the distance between the two designated positions (step S104). In response to the instruction from the CPU, the distance detection unit 831 detects the distance between the point A and the point B based on the coordinates of the two locations (point A and point B) stored in the coordinate storage unit 7.

  Next, the CPU instructs the distance determination unit 832 to determine whether or not the distance between the points A and B is greater than or equal to a predetermined threshold (step S105). As described above, when the predetermined threshold is 5 cm, the distance determination unit 832 determines whether the distance between the point A and the point B obtained by the distance detection unit 831 is 5 cm or more according to the instruction from the CPU. Determine whether or not. In this embodiment, since the distance between the two designated positions of point A and point B is 2 cm, the distance determination unit 832 determines that the distance between point A and point B is not greater than or equal to a predetermined threshold value.

  The CPU instructs the coefficient setting unit 833 to set a calculation coefficient related to the calculation of the jump page number (step S106). In response to an instruction from the CPU, the coefficient setting unit 833 sets a calculation coefficient.

  Specifically, since the distance determination unit 832 determines in step S108 that the distance between the point A and the point B is not equal to or greater than the predetermined threshold, “calculation coefficient = 0.5 × (2 locations) as in the above example. The distance of the designated position ÷ 5) ”is set. That is, the calculation coefficient is set to 0.2.

  Next, the CPU instructs the page number calculation unit 835 to calculate the jump page number (step S107). In response to the instruction from the CPU, the page number calculation unit 835 calculates the jump page number based on the calculation coefficient set by the coefficient setting unit 833 and the total page number of the image set.

  Specifically, as in the above-described example, the calculation is performed using the equation “number of jump pages = calculation coefficient × total number of pages in the image set”. The result of the calculation is “2.4”, but the number of jump pages is rounded down to the nearest “2”.

  Next, the CPU determines whether or not the number of jump pages calculated by the page number calculation unit 835 exceeds “1” (step S109). If the CPU determines that the jump page number does not exceed “1” (step S109: NO), the CPU instructs the page number calculation unit 834 to set the jump page number to “1” (step S111). In response to an instruction from the CPU, the page number calculation unit 834 sets the jump page number as “1”. Thereafter, the processing moves to step S110.

  On the other hand, when the CPU determines that the number of jump pages exceeds “1” (step S109: YES), the CPU instructs the direction designation receiving unit 835 to accept the jump direction designation (step S110). The direction designation accepting unit 835 accepts a jump direction designation based on the slide start point and the coordinates of the contact point stored in the coordinate storage unit 7. The detailed description of the direction specification reception by the direction specification reception unit 835 is as described above, and a description thereof will be omitted. In the following, it is assumed that the jump direction related to the accepted jump direction designation is “the ascending order from the page number of the displayed image”.

  Next, the CPU instructs the page number specifying unit 83 to specify the target page number (step S112). That is, the page number specifying unit 83 sets the page number jumped from “the page number of the displayed image in the ascending order” according to the jump direction designation received in step S110 by the obtained jump page number “2”. Identifies as a page number. In the present embodiment, since the page number of the displayed image is “1”, the target page number is “3”.

  The CPU determines whether or not the target page number specified by the page number specifying unit 83 is less than the first page number (step S113). This is performed by the CPU comparing “1” of the first page number of the image set stored in the storage unit 9 with the target page number. When the CPU determines that the target page number is less than the first page number (step S113: YES), the CPU sets the first page number as the target page number (step S115). The CPU sets the first page number “1” stored in the storage unit 9 as the target page number. Thereafter, the process moves to step S117.

  On the other hand, when the CPU determines that the target page number specified by the page number specifying unit 83 is not less than the first page number (step S113: NO), the target page number specified by the page number specifying unit 83 is the last page. It is determined whether the number is exceeded (step S114). This is performed by the CPU comparing the final page number “12” of the image set stored in the storage unit 9 with the target page number. When the CPU determines that the target page number specified by the page number specifying unit 83 exceeds the final page number (step S114: YES), the CPU sets the final page number as the target page number (step S116). The CPU sets the final page number “12” stored in the storage unit 9 as the target page number.

  When the CPU determines that the target page number specified by the page number specifying unit 83 does not exceed the final page number (step S114: NO), the image of the target page number specified by the page number specifying unit 83 is displayed. The information is displayed on the display unit of the display device 8 (step S117). On the other hand, when the target page number is set as the first page number or the last page number by the CPU, an image related to the first page number or the last page number is displayed on the display unit of the image display device 8. In the present embodiment, an image related to “3” that is the target page number specified by the page number specifying unit 83 is displayed on the display unit of the image display device 8. That is, the CPU acquires an image corresponding to the page number “3” from the storage unit 9 and instructs the display control unit 49 to display the image on the display unit of the image display device 8, and the image is displayed on the image display device. 8 is displayed on the display unit. FIG. 9 is an exemplary diagram showing an example of a search result obtained by the above-described image search process by the digital multi-function peripheral 1. Through the above-described processing, the target page number is specified as “3”, and the image of the page number “3” is displayed on the display unit of the image display device 8.

  Thereafter, the CPU determines whether or not a predetermined time has elapsed after displaying the image of the target page number on the display unit of the image display device 8 based on the timing result of the timing unit (step S118). When it is determined that the predetermined time has not elapsed (step S118: NO), the CPU waits until the predetermined time has elapsed.

  On the other hand, when the CPU determines that the predetermined time has elapsed (step S118: YES), the CPU determines whether or not the position designation has been received by monitoring the touch panel 81 (step S119).

  When it is determined that the position designation has been received (step S119: YES), the CPU returns the process to step S103. On the other hand, if the CPU determines that position designation has not been received (step S119: NO), the process ends.

  In this embodiment, the jump direction designation is received based on the position designation received by the position designation receiving unit 82 via the touch panel 81 by the user's contact operation within the frame of the “page turning” soft key. However, it is not limited to this. For example, the frame display unit 836 displays a “forward” or “return” soft key (designation reception frame), respectively, and accepts an ascending or descending jump direction designation via the “forward” or “return” soft key. You may comprise. FIG. 10 is an exemplary diagram showing another example of a configuration for accepting a jump direction designation.

  Further, in the first embodiment, the case where the user performs an operation in two stages, that is, an operation for specifying the position of two locations for calculating the number of jump pages and an operation for specifying the jump direction has been described as an example. However, the present invention is not limited to this, and these instructions may be received by a single operation of the user.

  For example, in the case where the first point related to the position designation received first among the two places is used as a reference, and the second point related to the position designation accepted next is the left side (or the upper side), the descending direction from the displayed screen When the second point is on the right side (or lower side) from the first point, the jump direction designation in the ascending order is accepted from the displayed screen. The configuration for calculating the number of jump pages based on the distance between the first point and the second point is the same as described above.

  In the first embodiment, the case where the image input device 3 reads a plurality of document bundles and displays an image related to the document bundles on the display unit of the image display device 8 is described as an example. Not a thing. For example, it goes without saying that the present invention can also be applied to the case where a filing mode is provided and filing data already stored in the storage unit 9 is displayed.
