Description

  The present invention relates to an image data editing technique for editing an image converted into digital data such as a manga so as to be in a predetermined display mode when displayed on a portable electronic device.

  In recent years, portable information terminals such as mobile phones and portable game terminals have become widespread, and on these portable information terminals, it is possible to watch TV and read digital data. Even a manga-like image, which is not suitable for display on a portable information terminal, can be enjoyed on a display screen of a mobile phone as the display device becomes higher in definition. For this reason, in recent years, services for electronically distributing comics to mobile phones, PDAs (Personal Digital Assistants) and the like have been spreading.

In order to convert an existing comic book into digital data, it is necessary to read it with a scanner or the like, shape an image using image editing software, and cut out and edit it for each frame. A technique for displaying on a small display device of a portable electronic device is described in Patent Document 1, for example.

  However, in the editing method using the manga paper configuration as it is, there is a problem that when the display is performed on a small display device of a portable electronic device, the content of the manga paper is too small to distinguish the content. In addition, there is a problem that the story development of the original manga is cut off if it is completely divided into frame units and sequentially displayed.

  The present invention has been made in view of such a problem, and is an image data editing capable of displaying image data such as manga with a natural feeling as if reading a manga paper on a small display device of a portable electronic device. The purpose is to provide technology.

  In order to achieve the above object, an image data editing apparatus of the present invention is an image data editing apparatus that edits image data to be displayed on a display screen of a portable electronic device so as to have a predetermined display mode, A designated area setting means for setting a plurality of designated areas with a step size as a unit to be displayed on the display screen of the portable electronic device for the image data, and from the set specific first designated area to the next to the first designated area Scroll display setting means for scroll-displaying the screen toward the second designated area to be displayed; an overlap ratio judging means for judging a mutual overlap ratio between the first designated area and the second designated area; and the overlap percentage judging means A scroll for setting a scroll time for scrolling the screen from the first designated area to the second designated area in accordance with the overlapping ratio determined in step And a le time setting means.

  By adopting such a configuration, it is difficult to measure the length on the display screen of the portable electronic device because it is displayed with pixels or the like on the editing screen, and the scroll speed can be set according to the length of the display screen. Even if it is difficult, by determining the overlapping ratio between the specified areas instead of the screen length and setting the scroll time, the editing screen displayed with pixels etc. can display the manga on the small display screen of the portable electronic device. The scroll display between frames or one frame can be set to a natural scrolling speed as if reading a manga paper.

  The scroll time setting means preferably sets the scroll time longer as the overlap ratio decreases. Thus, the scroll movement amount increases as the overlap ratio decreases, and the scroll time is set longer in accordance with the scroll movement amount. Therefore, a natural scroll speed as if reading the manga paper surface can be set.

  The scroll display setting means is set to automatically scroll continuously in the second designated area and the designated areas after the second designated area when scroll display is also performed in the designated areas after the second designated area. Is preferred. Thus, for example, when a long frame of a manga is displayed from the first designated area to the designated area after the second designated area, one frame is displayed by continuously scrolling from the first designated area to the second designated area. You can read with a natural line of sight as if you were reading a comic book.

  The scroll time setting means preferably sets a constant scroll time between the designated areas based on the determination result of the overlap ratio judging means when a continuous scroll is set between three or more consecutive designated areas. . As a result, the scroll time between the designated areas between the three or more consecutive designated areas becomes constant, so that when the overlapping ratio between the designated areas is close, reading can be performed with natural movement of the line of sight.

  The scroll time setting means preferably sets the respective scroll times based on the determination result of the overlap ratio determination means between the respective designated areas when the continuous scroll is set between the three or more designated areas. . Thereby, even if the overlap between each designated area is non-uniform, it can be read by a natural movement of the line of sight.

  It is preferable to further include step size setting means for setting a step size as a unit to be displayed on the display screen of the portable electronic device. Thereby, for example, a step size that is easy to see on a small display screen of a portable electronic device can be set according to the size and content of a comic book.

  Preferably, the image data is a manga, and all or a part of a manga frame is included in the designated area. Thereby, the scroll display between the comic frames and the scroll display showing the entire large frame can be set like a natural line of sight movement.

  In the image data editing method of the present invention, a plurality of designated areas are set with a step size as a unit to be displayed on the display screen of the portable electronic device for the image data to be edited displayed on the display screen of the portable electronic device. A setting step, a scroll display step for performing a setting to scroll the screen from the set specific first designated area to a second designated area to be displayed next to the first designated area, the first designated area, An overlap ratio determining step for determining a mutual overlap ratio of the second designated area, and scroll display from the first designated area toward the second designated area according to the overlap percentage determined by the overlap ratio determining means. A scroll time setting step for setting the scroll time.

  A computer program for causing a computer to execute the image data editing method of the present invention is a step size as a unit to be displayed on a display screen of the portable electronic device for image data to be edited displayed on the display screen of the portable electronic device. A designated area setting step for setting a plurality of designated areas, and a scroll display step for performing a setting for scrolling the screen from the set specific first designated area to the second designated area displayed next to the first designated area And an overlap ratio determining step for determining an overlap ratio between the first specified area and the second specified area, and the second specified area from the first specified area according to the overlap ratio determined by the overlap ratio determining means. A scroll time setting step for setting a scroll time for performing scroll display toward the designated area.

  The present invention has a configuration in which the scroll time is set by determining the overlapping ratio between the designated areas in the editing screen displayed on the display unit of the image data editing device. You can easily set the natural scrolling speed as if you were reading.

  Hereinafter, embodiments of the image data editing technique of the present invention will be described with reference to the drawings. However, the present invention is not limited to the following embodiments.

  FIG. 1 is a block diagram showing a configuration of an image data editing apparatus according to the present invention. An image data editing apparatus 1 shown in FIG. 1 includes a control unit 3 such as a CPU (Central Processing Unit) that controls the entire apparatus on a bus 2, a storage unit 4 that stores computer programs and data, information such as a keyboard, a mouse, and a scanner. An input unit 5 and a display unit 6 such as a display are connected.

  The storage unit 4 of the image data editing apparatus 1 stores, as computer programs, a step size setting means (step size setting step) 12, a designated area setting means (designated area setting step) 13, an order setting means (order setting step) 14, A scroll display setting means (scroll display setting step) 15, an overlap ratio determination means (overlap ratio determination step) 16 and a scroll time setting means (scroll time setting step) 17 are set, and an edit information storage section 20 is formed. ing.

  The step size setting means 12 sets a step size that is a unit displayed on the display screen of the portable electronic device. The step size is appropriately set according to the size of the comic book and the definition of the manga. For example, a square frame having a width half the width of the comic book (reference frame) can be set.

  The designated area setting means 13 selects an area to be displayed on the display screen of the portable electronic device within the range of the step size from the image data to be edited. For example, one frame of a manga (unit of scene development of a manga separated by a frame) is selected in one designated area. The image data of the selected designated area is stored in the editing information storage unit 20. The order setting unit 14 assigns the order of screen display to the selected designated area, and stores it in the editing information storage unit 20 in association with the designated area. The scroll display setting means 15 sets the presence / absence of scroll display, the number of the designated area for starting scrolling, the number of the designated area for ending scrolling, the direction of scrolling, etc., and saves them in the editing information storage unit 20. The overlap ratio determining means 16 determines the mutual overlap ratio between the designated area for starting scrolling and the designated area to be displayed next, and passes the data to the scroll time setting means 17. The scroll time setting means 17 sets the scroll time between the two designated areas for which the overlap ratio has been determined by the overlap ratio determination means 16 based on the correspondence relationship between the preset overlap ratio and the scroll time, and scroll display. The information is stored in the editing information storage unit 20 in association with the setting of the setting means 15.

  FIG. 2 is a flowchart for explaining the operation of the image data editing apparatus 1. Hereinafter, the image data editing method will be described based on this flowchart. First, the page of a comic book such as a comic book is read by the information input unit 5 such as a scanner, and the image is taken into the storage unit 4 of the image data editing apparatus 1 as digital data (S1). For example, one page of a comic book is captured as one image data. Manga image data stored in the storage unit 4 can be selected on a page basis by operating the information input unit 5 and displayed on the display unit 6.

  The user sets the step size, which is a unit to be displayed on the display screen of the portable electronic device, according to the read comic book by the step size setting means 12 (S2). For example, when the step size is set to a square range that is half the width of the comic book, this range is displayed on the display screen of the portable electronic device, for example, 240 pixels × 240 pixels.

  The designated area is selected with the step size set above by the designated area setting means 13 via the information input section 5 for the image data of one page of manga displayed on the display section 6 (S3). For example, if one frame of a comic book falls within the step size range, that one frame is selected as one designated area. If a plurality of small frames fit within the step size, the plurality of frames are selected as one designated area. In the case of a frame that exceeds the step size, only the necessary part in the story of this frame can be selected. In addition, for a large frame exceeding the step size, and a frame that needs to be displayed as a whole, a specified area is selected so as to cover the entire frame with two or more specified areas, and these specified areas are associated with each other.

  The selected designated area is assigned the screen display order manually by the operation of the order setting means 14 via the information input unit 5 or automatically by the order setting means 14 (S4). Further, for example, when the entire frame is covered with a plurality of designated areas such as one long frame, these designated areas are associated by the order setting means 14.

  Next, scroll time setting means 17 for setting the time required for scrolling when scrolling from a specified area (hereinafter referred to as a first specified area) toward a specified area (hereinafter referred to as a second specified area) to be displayed next. The process will be described. The first designated area and the second designated area may be set in the same frame, or may be set in different frames. When the first designated area and the second designated area are set in the same frame, the entire frame is displayed in scroll display. When the first designated area and the second designated area are set to different frames, scroll display between frames is performed.

  When the scroll display from the first designated area to the second designated area is set, the scroll display setting means 15 associates the scroll display setting with the first designated area (S5). The scroll setting includes the presence / absence of scroll, the scroll direction, and the like, and the scroll speed uses the value set by the scroll time setting means 17.

  When scrolling is set in the first designated area, the scroll time is set according to the moving distance between the second designated area and the first designated area that is scroll-displayed from the first designated area, so that the natural line of sight moves. This is preferable because scroll display is performed at a corresponding speed. However, since the designated area is displayed at a predetermined size on the display unit 6 and is not displayed at the size of the display screen of the portable electronic device, the scroll speed corresponding to the actual length of the display screen is set. Difficult to do.

  Therefore, in the present invention, the movement amount of the scroll display is determined by the overlapping ratio of the first designated area and the second designated area. When it is determined that the scroll display is set in the first designated area (“YES” in S5), the overlap ratio determining unit 16 determines the overlap ratio between the first designated area and the second designated area (S6). Specifically, the overlap ratio determining means 16 determines the overlap ratio from the difference between the position of the center point of the second designated area and the position of the outer edge in the scroll direction of the first designated area. According to this method, the overlapping ratio between the designated areas can be easily measured.

  A method for determining the overlap ratio will be described with reference to FIG. FIG. 3 is a conceptual diagram for calculating the overlapping ratio of the first designated area 100 and the second designated area 200 when scrolling in the horizontal direction from the first designated area 100 on the right side toward the second designated area 200 on the left side. By calculating the ratio of the width of the second designated area 200 to the horizontal distance between the position of the upper left corner 101 (left outer edge) of the first designated area 100 and the position of the geometric center 201 of the second designated area 200, The overlapping ratio between the designated area 100 and the second designated area 200 is measured.

  As shown in FIG. 3A, the horizontal distance between the center point 201 of the second designated area 200 and the upper left corner point of the first designated area 100 is −1/5 of the width of the second designated area 200 (center point). If the left outer edge is on the left side, the overlap ratio is 1/2 − (− 1/5) = 3/5, and the horizontal pixel of the display screen of the portable electronic device is 240. The length shown by scrolling is 240 + 240 × (1−3 / 5) = 336 pixels.

  As shown in FIG. 3B, when the center point 201 of the second designated area 200 coincides with the left outer edge of the first designated area 100, the overlapping ratio becomes 1 / 2-0 = 1/2, and the portable electronic device If the horizontal pixel of the display screen is 240, the length shown by scrolling is 240 + 240 × (1-1 / 2) = 360 pixels.

  As shown in FIG. 3C, the horizontal distance between the center point 201 of the second designated area 200 and the left outer edge of the first designated area 100 is 1/5 of the width of the second designated area 200 (left of the center point). If the outer edge is on the right side, the overlap ratio is 1 / 2− (1/5) = 2/5, and if the horizontal pixel of the display screen of the portable electronic device is 240, scrolling is possible. The length to be displayed is 240 + 240 × (1-2 / 5) = 384 pixels.

  As shown in FIG. 3D, the distance between the center point 201 of the second designated area 200 and the left outer edge of the first designated area 100 is 1/3 of the width of the second designated area 200 (the left outer edge from the center point). Is the right side), the overlap ratio is 1 / 2− (1/3) = 1/3, and if the horizontal pixel of the display screen of the portable electronic device is 240, the overlap is displayed. The length is 240 + 240 × (1-1 / 3) = 400 pixels.

  As shown in FIG. 3E, the horizontal distance between the center point 201 of the second designated area 200 and the left outer periphery of the first designated area 100 is 1/2 of the width of the second designated area 200 (from the center point). If the left outer edge is on the right side, the overlap ratio is 1 / 2- (1/2) = 0, and if the horizontal pixel of the display screen of the portable electronic device is 240, the overlap is displayed. The length is 240 + 240 × (1-0) = 480 pixels.

  The relationship between the overlap ratio and the scroll time setting is stored in advance in the storage unit 4 in the form of a table or function. The scroll time setting means 17 refers to the relationship between the overlap ratio and the scroll time setting, and sets the scroll time (scroll speed) according to the overlap ratio determined by the overlap ratio determination means 16 (S7). The set scroll time is stored in the editing information storage unit 20 as a part of the setting of the scroll display setting means 15 in association with the first designated area.

Examples of scroll time setting values corresponding to the overlapping ratios shown in FIGS. 3A to 3E are summarized in the following table. By setting the scroll time according to the overlapping ratio between the designated areas, the scroll length can be obtained in units of the display screen of the portable electronic device.

  The scroll display described above is a scroll display from the first designated area to the second designated area. When scroll display is continuously performed from the second designated area to the third designated area to be displayed next, Further, there may be a case where three or more designated areas are continuously scroll-displayed from the third designated area toward the fourth designated area to be displayed next. Therefore, a scroll time setting method in such a case will be described.

  FIG. 4 is a conceptual diagram schematically showing the overlap of the first designated area, the second designated area, and the third designated area that are continuously scroll-displayed. The overlapping ratio between the first designated area 100 and the second designated area 200 and the overlapping ratio between the second designated area 200 and the third designated area 300 shown in FIG. 4 are substantially the same. In the manga, when, for example, a horizontally long frame from the first designated area 100 to the third designated area is read, if the continuous scroll display is used, the first designated area 100 to the third designated area 300 are one. It clearly shows that it is a single piece, and does not interfere with story development.

  In this case, a setting for automatically performing scroll display is associated with the second designated area 200 in the middle. Further, the setting of the scroll time from the first designated area 100 to the second designated area 200 and the setting of the scroll time from the second designated area 200 to the third designated area 300 are performed by the overlap ratio determining means 16 and the scroll time setting means 17. Can be set independently from the overlapping ratio of the first specified area 100 and the second specified area 200 and the overlapping ratio of the second specified area 200 and the third specified area 300, respectively. Similarly, the automatic setting of scroll display and the setting of the scroll time are sequentially performed for the fourth and subsequent designated areas to be displayed after the third designated area 300 and the continuous scroll display over four or more designated areas can be set. it can.

  In addition, when a plurality of continuous scroll displays are set, each scroll time is not set individually, for example, even if a constant scroll time unified by the average time or the representative time of these scroll times is set. Good.

  The above description is a case where the scrolling display is performed in the horizontal direction from the right side to the left side. However, even when the first designated area and the second designated area, and further the third designated area and beyond are connected in the vertical direction, the same applies. The scroll time can be set based on the mutual overlapping ratio between the designated areas.

  The technology of the present invention can be used in a content distribution business for distributing manga images to mobile electronic devices such as mobile phones.

It is a block diagram which shows the structural example of the image data editing apparatus of this invention. It is a flowchart explaining the method to set scroll speed. It is a conceptual diagram explaining the method of determining the overlap ratio of two designated area | regions. It is a conceptual diagram explaining the overlap ratio of three designation | designated areas.
