Next, an example of the processing operation of the electronic album editing application 105 when performing the page turning process as described above will be described. Hereinafter, a case where the total number of pages of the electronic album 303 is 10 will be described as an example.
FIG. 8 is a flowchart for explaining an example of the main processing operation when displaying a state in which the pages of the electronic album 303 are turned.

  In step S <b> 1 of FIG. 8, the data control unit 201 acquires the current spread page of the electronic album 303 displayed on the electronic album display screen 301 from the GUI control unit 202. In the present embodiment, the spread pages are identified by being digitized as shown in FIG. For example, the spread page identification number nPage of “−1” is set for the spread pages of the front cover and the back cover. Therefore, when the current spread page of the electronic album 303 displayed on the electronic album display screen 301 is the spread page of the front cover and the back cover, the data control unit 201 sets “−1” as the spread page identification number nPage. To get.

  Next, in step S <b> 2, the data control unit 201 acquires a spread page to be displayed next from the GUI control unit 202. The GUI control unit 202 determines the spread page to be displayed next based on the operation content of the “page turning” button 304, and outputs the spread page identification number for the determined spread page to the data control unit 201. For example, when the spread page currently displayed is a spread page of the front cover and the back cover, and the “>>” button 304a is pressed, the spread page to be displayed next is “Turn the cover back” and This is a first page spread page. Therefore, the data control unit 201 acquires “0” as the spread page identification number nPage. In step S2, if the “page turning” button 304 is not operated, the data control unit 201 acquires the spread page identification number nPage corresponding to the spread page currently displayed.

  Next, in step S3, the data control unit 201 determines whether or not the spread page identification number nPage acquired in step S1 matches the spread page identification number nPage acquired in step S2. That is, the data control unit 201 determines whether there is a spread page to be displayed next. As a result of the determination, if the spread page identification number nPage acquired in step S1 matches the spread page identification number nPage acquired in step S2, and there is no spread page to be displayed next, the page is turned. Since there is no need, the process is terminated.

  On the other hand, when there is a spread page to be displayed next, the process proceeds to step S4, and the data control unit 201 determines whether or not the spread page identification number nPage acquired in step S1 is “−1”. That is, the data control unit 201 determines whether or not the currently displayed spread page is a spread page of the front cover and the back cover. As a result of the determination, if the spread page identification number nPage acquired in step S1 is “−1” and the currently displayed spread page is the spread page of the front cover and the back cover, the process proceeds to step S5. The cover turning process described with reference to FIG. The details of the cover turning process will be described later with reference to FIG.

  On the other hand, if the spread page currently displayed is not a spread page of the front cover and the back cover, the process proceeds to step S6, and the data control unit 201 has the spread page identification number nPage acquired in step S2 of “−1”. It is determined whether or not. That is, the data control unit 201 determines whether or not the next spread page to be displayed is a spread page on the front cover and the back cover. As a result of the determination, if the spread page identification number nPage acquired in step S2 is “−1” and the spread page to be displayed next is the spread page of the front cover and the back cover, the process proceeds to step S5. Then, the cover turning process is performed to finish the process.

  On the other hand, if the spread page to be displayed next is not the front and back cover pages, the process proceeds to step S7, and the data control unit 201 acquires the spread page identification number nPage acquired in step S2 in step S1. It is determined whether or not the spread page identification number is larger than nPage. That is, the data control unit 201 determines whether the turning direction is the forward direction or the reverse direction. As a result of the determination, if the spread page identification number nPage acquired in step S1 is smaller than the spread page identification number nPage acquired in step S2 and the turning direction is the reverse direction, the process proceeds to step S8, and the data control unit 201 sets “0” as the turning direction identification number ForwardPage.

  On the other hand, if the spread page identification number nPage acquired in step S1 is larger than the spread page identification number nPage acquired in step S2 and the turning direction is the forward direction, the process proceeds to step S9, and the data control unit 201 “1” is set as the turning direction identification number ForwardPage.

  As described above, when the turning direction identification number ForwardPage is set, the process proceeds to step S10, the middle page turning process as described with reference to FIGS. 5 and 6 is performed, and the process is terminated.

  Here, an example of the middle page turning process will be described in detail with reference to the flowchart of FIG. Here, as shown in FIG. 11, the left side of the currently displayed spread page 1101 is “A” and the right side is “B”, and the left side of the spread page 1102 to be displayed next is “C”. A case where the right side is “D” will be described as an example.

  First, in step S21, the data control unit 201 refers to the turning direction identification number set in step S8 or S9 in FIG. 8, and determines whether the page turning direction is the forward direction. As a result of this determination, if “1” is set as the turning direction identification number in step S9 of FIG. 8, and the page turning direction is the forward direction, the process proceeds to step S22.
