  The page of the picture book image displayed in the reproduction image display area 29 can be turned one page at a time by operating the page turning buttons 39 to 41 and the automatic page turning button 42 or jumped to the first page. However, there is a desire to jump to the previous page or the previous page. This demand can be met by the method described later.

  FIG. 1 is a diagram illustrating a display example of the display device 4. In FIG. 1, the screen 27 displays a mode switch display area 28, a reproduction image display area 29, a reproduction operation area 30, and a horizontally long bar graph 31 indicating a time axis provided below the reproduction image area 29. In the mode switch display area 28, an image creation mode switch 19, an effect setting mode switch 23, an effect image reproduction switch 26, and a print switch 32 are provided. A current mode display area 33 for displaying the currently selected mode is provided above the image creation mode switch 19. The current mode is an effect image playback mode, and “play” is displayed.

  The bar graph 31 corresponds to two pages of each spread image (hereinafter, two pages constituting the spread image are referred to as “one sheet”. However, the cover of the picture book is one spread image on one page on one side). Representing each playback time. The bar graph 31 is added with a scale with a length corresponding to the reproduction time of each spread image, and the image up to immediately before the spread image currently reproduced is displayed in a first color area 34 (for example, red), A spread image currently being reproduced is indicated by a second color area 35 (for example, blue). As reproduction of the current spread image proceeds, the length of the second color area 35 becomes shorter and the length of the first color area 34 becomes longer. Thereby, the reproduction time of each spread image with respect to the entire picture book can be determined, the position of the spread image currently being reproduced with respect to the entire picture book can be determined, and the current position in the spread image being reproduced can be determined.

  In the reproduction operation area 30, a reproduction start button 36, a stop button 37, a cue button 38 in the reproduction page, and page turning buttons 39, 40, and 41 are displayed. The page turning button 39 is a switch for advancing display to the next page, and the page turning button 41 is a switch for returning the display to the previous page. The page turning button 40 is a switch for jumping to the first page and displaying it. The page turning buttons 39, 40 and 41 are manual operation switches. An automatic turning button 42 for automatically turning the page after the image reproduction of the displayed page is completed is provided.

  FIG. 1 shows a screen during execution of the effect image playback mode. The playback image display area 29 shows an example in which a picture book is displayed in a two-page spread format. Reference numeral 43 denotes a bookshelf button for accessing an image file of a picture book that has already been read, and is used when the picture book image is read from the image file and edited or reproduced. Reference numeral 44 denotes an off switch, which is used when the image display is finished.

  FIG. 7 is a diagram illustrating changes in the bar graph 31 over time. As shown in FIG. 7A, this digital picture book is composed of 15 spread screens. The reproduction time of the effect of each spread image is represented by one scale on the bar graph 31. FIG. 7A shows that the ninth spread of the 15 spread images is displayed, and the effect added to the ninth spread image is being reproduced. The second color area 35 is shortened by a length L1 corresponding to the amount of time that has elapsed since the reproduction effect added to the ninth spread image is started at time T1. The one-color region 34 is long.

  FIG. 7B shows a state where the reproduction of the effect added to the ninth spread is approaching the end. The second color area 35 is almost disappearing.

  FIG. 7C shows a state in which the reproduction of the effect added to the tenth spread image is started, and the second color area 35 is a bar graph corresponding to the tenth spread image. It covers the entire 31 segment areas 58.

  The display of the bar graph 31 is performed so that the second color area 35 of the bar graph 31 is eroded by the first color area 34 as the reproduction time elapses, but the present invention is not limited to this configuration. For example, after the reproduction of the setting effect of the spread image is started, the second color area 35 extends with the passage of time, and the divided area of the bar graph 31 corresponding to the reproduction time of the spread image is filled with the second color. In this case, the second color region 35 may be repainted to the first color.

  Further, the boundary line between the first color region 34 and the second color region may move to the right as the playback time elapses. In this case, the coloring of the first color and the second color may be omitted.

  FIG. 8 is a block diagram showing the main functions of the image display control apparatus 100 for displaying the page playback time as a bar graph. In FIG. 8, the bar graph segment length calculation unit 59 calculates the reproduction time of each spread image based on the reproduction time of each page stored in the effect setting information storage unit 24, and further, the spread image of each spread image. The ratio of the reproduction time to the total reproduction time of all spread images is calculated. The bar graph display unit 60 internally divides the bar graph 31 of a predetermined length by the ratio of the reproduction time of each spread image, and displays the bar graph 31 having the length of the divided area according to the ratio of the reproduction time of each spread image. 4 is displayed as shown in FIG.

  In the reproduction counter 61, a counter value proportional to the reproduction time of each spread image is set. The reproduction time of each spread page is detected with reference to the reproduction time of each page stored in the effect setting information storage unit 24. The reproduction counter 61 decreases the counter value every time a predetermined number of clock signals of the CPU 1 are input when the reproduction of the effect set for the spread image is started, and when the counter value becomes zero, A reproduction end signal is input to the page counter 62. In the page counter 62, the number of spread images currently opened is set as an initial value, and the number of spread images is updated each time a reproduction end signal is input from the reproduction counter 61.

  The first color display unit 63 outputs an instruction to add the number of spread pages and the first color (for example, red) region 34 to the bar graph display unit 60 according to the value of the page counter 62. The bar graph display unit 60 fills with the first color up to the scale of the corresponding spread page on the bar graph 31 (or up to the scale of the eighth spread image if the spread image is the ninth image). Further, the first color display unit 63 reads the initial value and the current value of the counter value from the reproduction counter 61, and sets the ratio of the current value to the initial value as the elapsed time of the reproduction time of the currently displayed spread image. The first color area 34 having a length corresponding to the ratio is added and displayed.

  The second color display unit 64 displays an instruction to fill the length obtained by subtracting the elapsed time of the reproduction time with the second color (blue) in the divided area of the bar graph 31 corresponding to the spread image currently displayed. Input to the unit 60.

  Next, functions that can be added to the bar graph 31 will be described. Each segmented region (region sandwiched between scales) of the bar graph 31 represents each spread image. Therefore, by pointing (pointing) each segmented area representing the spread image of the bar graph 31 with the input device 9, the image displayed in the reproduction image display area 29 in FIG. 1 is switched to the specified spread image. be able to.

  FIG. 9 is a diagram illustrating a display example of an image in which display switching of page images (page jump) is possible. FIG. 9 shows an example in which the mouse cursor is moved with the mouse as the input device 7 and pointing to the bar graph 31. When the segmented area 65 is pointed, an image of one spread image represented by the segmented area 65 on the pointed bar graph 31 is read from the image storage unit 20, and a preview image 66 obtained by reducing the spread image is the bar graph 31. Displayed above. The display position of the preview image 66 is preferably shifted to the left or right on the bar graph 31 so as not to overlap the cursor C1 at the pointing position. In this example, the preview image 66 is displayed shifted to the right with respect to the cursor C1. This is to prevent the preview image 66 and the cursor from overlapping by shifting the display position in this way, and the details of the cursor C1 and the preview image 66 from becoming difficult to see.

  When the pointing position is shifted with the bar graph 31, the preview image is switched one after another. When the desired spread image is displayed as the preview image, clicking the mouse at the pointing position corresponds to the preview image. The spread image to be displayed is displayed in place of the spread image currently displayed in the reproduction image display area 29.

  Note that the preview image 66 is displayed so as to overlap the spread image and the bar graph 31, so that the part of the spread image and the bar graph 31 is hidden by the preview image 66. Thus, in order to prevent a part of the spread page or the like from being hidden by the preview image, it is preferable to display the preview image in a translucent manner.

  The preview image 66 allows the user to recognize the rendering effect set on the spread page represented by the preview image 65.

  FIG. 10 is a diagram illustrating an example of a translucent preview image. In this figure, since the pointing position (cursor C1) is on the right side, the preview image 66 is displayed shifted to the left side of the cursor C1. As a result, the preview image 66 is displayed so as to partially overlap the position where the operation icon 67 is displayed. Even in such a case, since the preview image 66 is displayed in a translucent manner, the operation icon 67 and the bar graph 31 can be seen through the preview image 66.

  FIG. 11 is a flowchart illustrating an example of page jump processing. In FIG. 11, in step S1, the presence / absence of pointing on the bar graph 31 is determined. If step S1 is affirmative, the process proceeds to step S2, and the pointed position corresponds to the divided area representing the first spread image with reference to the coordinates of each divided area of the bar graph 31 stored in advance. Detect position.

  In step S <b> 3, image data for two pages (only one page in the case of a cover) constituting the spread image represented by the detected divided area is read from the image storage unit 20. In step S4, a preview image is generated by reducing the read image data of two pages of spread images at a preset reduction rate. In step S5, the created preview image is displayed on the bar graph 31 at a position shifted from the pointing position by a predetermined amount to the left and right.

  In step S6, it is determined whether or not the pointing position has been clicked. If step S6 is positive, the process proceeds to step S7, and the image data of the spread image represented by the preview image is read from the image storage unit 20. Then, the process proceeds to step S8, and the read spread image is displayed in the reproduction image display area 29.

  If step S6 is negative, the process proceeds to step S9, where it is determined whether or not a position on the bar graph 31 that is different from the previous pointing position has been pointed, that is, whether or not the pointing position has moved to another segmented area. If step S9 is negative, the process returns to step S6. If step S9 is positive, the process proceeds to step S2.

  FIG. 12 is a functional block diagram of main parts of the image display control apparatus 100 showing functions necessary for the page jump process. In FIG. 12, when the bar graph display area in the spread image displayed in the reproduction image display area 29 is pointed by the input device 7, the pointing position determination unit 68 sends the position coordinates to the bar graph segmented area detection unit 69. input. The bar graph segmented area detecting unit 69 searches the bar graph segmented coordinate storage unit 70 based on the position coordinates input from the pointing position discriminating unit 68 and extracts a segmented area representing the spread page. The bar graph segmented coordinate storage unit 70 stores X / Y coordinate values indicating each segmented region of the region where the bar graph 31 is displayed, and outputs information indicating the segmented region including the coordinates of the pointed position.

  Information indicating the segmented area, that is, information indicating the number of the second spread image is input to the preview creating unit 71. The preview creating unit 71 reads out image information for two pages constituting the spread page instructed from the image storage unit 20, reduces the image information at a planned reduction rate, and outputs it to the preview display unit 72 (display device 4).

  The click operation determination unit 73 determines whether or not a mouse click has been performed at the pointed position. If it is determined that the click has been performed, a read instruction with a page number is input to the image storage unit 20. The image storage unit 20 inputs the image information of the input page number to the spread display unit 74 (display device 4). In accordance with the input image information, the spread display unit 74 causes the spread display unit 74 to display an image of the spread page including the input page number.

  When the effect image playback switch 26 is turned on, the effect reproduction unit 75 reads the effect setting information from the effect setting information storage unit 24 and reproduces the effect set on the page displayed on the spread display unit 74. . Reproduction of the effect is not limited to turning on the effect image reproduction switch 26, and the spread page is automatically included with the effect at the same time when the spread page is reproduced in response to a click operation on the pointing position. May be played.

  FIG. 13 is a diagram illustrating an example in which effect setting information is displayed in an image. In FIG. 13, information (marks) A and B indicating the effect is displayed in the effect setting area 82 of the character 81 on the right page of the spread image 80, and the effect setting area 84 of the character 83 indicates the effect. Information C and D are displayed, and information E indicating the effect is displayed in the effect setting area 86 of the character 85. In addition, information F and G indicating the effect of the effect are displayed in the effect setting area 87 set in the sentence on the left page of the spread image 80. Information A to G indicates that effects such as sound, image enlargement / reduction, image rotation, image movement, sound, and BGM are set in each effect setting area. In FIG. 13, the preview image 88 displayed on the bar graph 31 also includes an effect mark.
