Description

The present invention relates to an image processing system capable of displaying a clearer image when image data composed of raster data is enlarged and displayed.

  Currently, there is a mechanism that allows browsing of digitized comic data on mobile terminals such as mobile phones, PHS, and PDAs. This is done by downloading each frame of a comic as a single image data from a predetermined server to a mobile terminal and displaying the image data of that frame on the mobile terminal.

  However, the screen of the portable terminal is small, and there is a drawback that it is difficult to see the characters and frames themselves written in the “speech balloon” in which the speech of the character is shown as it is. Therefore, in general, the image data of the frame displayed on the mobile terminal is enlarged so as to be easily viewed by the user. Conventional examples showing the expansion of frames on such portable terminals are shown in Patent Documents 1 to 3 below.

  As described in the above-mentioned patent document, by enlarging and displaying the image data displayed on the mobile terminal as it is, the image data is displayed in a large size, which makes it easy for the user to see. Generally, raster data (also referred to as raster image or raster image) is used for such image data. Raster data is so-called bitmap data, and is a data format that represents an image by designating what color is displayed for each pixel.

  When such raster data is enlarged and displayed, the enlarged image data is not displayed clearly. This is because, for example, when the image is enlarged and displayed at a magnification of 2 times, the color expressed by one pixel of the original image data is displayed with the total of four pixels, two pixels in the vertical direction and two pixels in the horizontal direction in the enlarged image data. Because it becomes. As a result, the image is likely to have a jagged outline and is not displayed neatly.

  There is a method of displaying the image after converting it from raster data to vector data as a method of displaying it clearly even if enlarged display is performed, but there is a problem that it takes time to convert from raster data to vector data. Therefore, a system for neatly displaying enlarged image data as raster data is desired.

  An image processing system 1 of the present invention includes an image generation system 2 that performs image data generation processing, and an image display system 3 that displays image data generated by the image generation system 2. The image generation system 2 is a system that performs processing related to original image data (original image data) on a computer, and the image display system 3 is a system that displays image data on a mobile terminal, for example. The image display system 3 exhibits a greater effect when functioning on a device having a small display device 22 such as a portable terminal, but even if the display device 22 is not as small as a normal computer terminal, the effect is exhibited. It can be demonstrated.

  A conceptual diagram of the image processing system 1 is shown in FIG. An example of a hardware configuration of a computer terminal that implements the image generation system 2, a portable terminal that implements the image display system 3, or a computer terminal is shown in FIG.

  The computer terminal or portable terminal used in the present invention includes an arithmetic device 20 such as a CPU that executes arithmetic processing of a program, a storage device 21 such as a RAM or a hard disk that stores information, and processing results and storage devices of the arithmetic device 20. And a communication device 24 that transmits and receives information stored in the network 21 via a network such as the Internet or a LAN. Each function constituting each system of the present invention executes the processing of the present invention by reading the means (program, module, etc.) for executing the processing into the arithmetic unit 20. When each function uses the information stored in the storage device 21 in the process, each function reads the corresponding information from the storage device 21 and uses the read information for the process in the arithmetic device 20 as appropriate. Further, these computer terminals and portable terminals may include an input device 23 such as a keyboard, a mouse, and a numeric keypad, a display device 22, and the like.

  Each means in the present invention is only logically distinguished in function, and may be physically or practically the same area.

  The image generation system 2 includes an image reading unit 4, an edge image extraction unit 5, a normal image generation unit 6, and a download data generation unit 7. The image display system 3 includes a download data reading unit 8, an image storage unit 9, and a display processing unit 10.

  The image generation system 2 is a system that generates data (download data) to be downloaded to the image display system 3 based on the original image data. The image display system 3 downloads download data from a predetermined server and downloads it. This is a system for displaying a normal image (described later) in data.

  The image reading unit 4 reads original image data composed of raster data into the image generation system 2. For example, FIG. 5B shows an example of original image data.

  The original image data read here is reduced to a predetermined size (vertical and horizontal size) by a normal image generation unit 6 described later for display by the image display system 3. FIG. 5A shows an example of image data (normal image) whose size has been reduced.

  The edge image extraction unit 5 extracts contour pixels in the original image data. Data obtained by extracting contour pixels from the original image data is defined as an edge image. An example of the edge image is shown in FIG. In FIG. 6, data obtained by extracting all contour pixels for a part of the original image data (right side from the character) is an edge image. However, all or part of the contour pixels of the original image data are extracted. And it is good as an edge image. For example, it is possible to arbitrarily set only the outline of the character, only the speech bubbles. A plurality of edge images may be generated for one piece of original image data. For example, the original image data may be divided into a right side and a left side, and two edge images of a right side edge image and a left side edge image may be generated.

  The normal image generation unit 6 reduces the original image data read by the image reading unit 4 to a predetermined size. For example, when the image display system 3 is realized by a mobile terminal, the image display system 3 is reduced to a predetermined size such as a size suitable for the display device 22 of the mobile terminal, for example, 240 pixels × 240 pixels or 120 pixels × 120 pixels. The image data obtained by reducing the original image data to a predetermined size is defined as a normal image. An example of a normal image is shown in FIG.

  The download data generation unit 7 associates the normal image generated by the normal image generation unit 6 with the edge image. The associated normal image and edge image are used as download data. Since the size of the original image data is reduced in the normal image, the data amount is not large. Also, since the edge image is information on the pixels of the contour of the original image data, the data amount is not large. Therefore, even if these two are associated, the amount of data is not large. The download data generation unit 7 may manage the normal image and the edge image as one image data or may manage them separately.

  In the case of the above example, as the download data, the normal image in FIG. 5A and the edge image in FIG. 6 are associated with each other, and these become download data.

  The download data generated by the download data generation unit 7 is stored in the storage device 21 of the image generation system 2 or the storage device 21 of a predetermined image server.

  The download data reading unit 8 acquires download data from the storage device 21 of the image generation system 2 or the storage device 21 of a predetermined image server, and associates the normal image and the edge image in the download data with each other in the image storage unit 9. Remember.

  In the image storage unit 9, download data is stored in a storage device 21 of a computer terminal or mobile terminal that implements the image display system 3.

  The display processing unit 10 first displays a normal image on a display device 22 of a computer terminal or portable terminal that implements the image display system 3 and receives a normal image enlargement request, and then displays the normal image with a predetermined size. The image is enlarged and displayed with the edge image superimposed on it. FIG. 7A shows a case where a normal image is enlarged and displayed, and FIG. 7B shows a case where an edge image is superimposed on the normal image shown in FIG.

  Next, the processing process of the present invention will be described with reference to the flowcharts of FIGS. In the following description, a case where the image display system 3 is realized by a mobile terminal will be described.

  Although the case of a comic as an image distributed to a user will be described, the present invention is not limited to this and can be applied to various types of images.

  First, the original image data is read into the image reading unit 4 of the image generation system 2 as an original image of the image to be distributed to the user (S100).

  When the original image data is read by the image reading unit 4, the edge image extraction unit 5 extracts pixels constituting the contour from the original image data (S110). On average, when the edge image is extracted from the original image, the inventor's research has found that the amount of data is 10% or less of the original image data, and more than 75% of the original image data is compressed. The rate has improved.

  Further, the normal image is generated by reducing the original image data read by the image reading unit 4 to a predetermined size designated by the portable terminal (S120). Then, the download data generation unit 7 performs a process of associating the generated normal image with the edge image (download data generation process) (S130). The associated normal image and edge image are download data.

  The download data generated in S130 is stored in the storage device 21 of the image generation system 2 or the storage device 21 of a predetermined image server (S140).

  By performing the above processing, data to be downloaded to the mobile terminal can be generated.

  Next, when the user of the mobile terminal wants to browse the image, the storage device 21 of the image generation system 2 or the predetermined image is obtained through a network such as the Internet by performing a predetermined operation from the mobile terminal. The storage device 21 of the image generation system 2 or a predetermined image server that has made a download data acquisition request from the server and has received the request transmits the download data to the mobile terminal. The download data is read by the download data reading unit 8 (S200).

  The download data read in S200 is stored in the storage device 21 (image storage unit 9) of the portable terminal.

  When the download is normally completed, the display processing unit 10 displays the normal image included in the download data on the display device 22 of the portable terminal (S210). The normal image displayed at this time is a small size for a portable terminal.

  When the user who has viewed this normal image wants to enlarge and display the normal image, the display processing unit 10 receives an enlargement request by inputting a predetermined operation from the input device 23 of the portable terminal (S220).

  Upon receiving the enlargement request, the display processing unit 10 enlarges the normal image displayed in S210 at a predetermined magnification, and displays it on the display device 22 of the portable terminal (S230). At this time, the size for enlarging the normal image is preferably the same size as the original image data. FIG. 7A shows a case where a normal image is enlarged and displayed.

  After the normal image is enlarged and displayed, the edge image associated with the normal image stored in the image storage unit 9 is superimposed and displayed on the normal image. The image in this state is shown in FIG.

  In this way, the edge image is associated with the normal image, and when the normal image is enlarged and displayed together, the image is displayed more clearly than the simple enlargement of the normal image with a small amount of data. It becomes possible. Further, since no vector data is used, it is not necessary to perform conversion processing from raster data to vector data at the time of image generation, and the burden of image generation can be reduced.

  Next, in the above-described embodiment, a case where the size when the normal image is enlarged and displayed is not the same as the size of the edge image will be described. In this case, the edge image cannot be neatly superimposed and displayed on the enlarged normal image. Therefore, the display processing unit 10 superimposes and displays the edge image after reducing the edge image to match the size of the enlarged normal image.

  For example, assume that the size of the original image data (edge image) is 400 pixels vertically and 400 pixels horizontally, and the size of the normal image is 100 pixels vertically and 100 pixels horizontally. Then, it is assumed that a request for enlarging and displaying a normal image is received twice.

  In this case, since the size of the enlarged normal image is displayed with 200 pixels vertically and 200 pixels horizontally, the display processing unit 10 sets the size of the edge image stored in the image storage unit 9 to 50% for each of the vertical and horizontal sizes. to shrink. Then, the size of the reduced edge image is 200 pixels in length and 200 pixels in width, the size of the enlarged normal image is the same as the size of the reduced edge image, and if the reduced edge image is superimposed on the enlarged normal image, It will be displayed neatly.

  The display processing unit 10 may automatically reduce and display the edge image to the same size in accordance with the enlarged size of the normal image.

  The second embodiment is an effective processing method when the enlargement size of the normal image is different for each portable terminal or when the enlargement size can be arbitrarily designated. However, when the enlargement size of the normal image is determined in advance, the edge image extraction unit 5 of the image generation system 2 can display the outline of the original image data, rather than providing the display processing unit 10 with reduced display of the edge image. When the pixels are extracted, the edge image may be generated after being reduced to a predetermined size (a size that matches the enlarged size of the normal image).

  For example, as described above, for example, the size of the original image data (edge image) is 400 pixels long and 400 pixels wide, the size of the normal image is 100 pixels long and 100 pixels wide, and the size of the enlarged normal image is It is assumed that the height is 200 pixels and the width is 200 pixels.

  In this case, the edge image extraction unit 5 generates image data composed of contour pixels extracted from the original image data as an edge image after reducing the vertical and horizontal sides by 50%. Then, the size of the generated edge image is 200 pixels vertically and 200 pixels horizontally.

  In the download data generation unit 7, the normal image generated by the normal image generation unit 6 is associated with the edge image to obtain download data.

  The download data is downloaded by the portable terminal by the download data reading unit 8 and stored in the image storage unit 9. The display processing unit 10 displays the normal image stored in the image storage unit 9, and further receives an enlargement request from the input device 23, whereby the enlarged normal image (the size of the enlarged normal image is 200 pixels vertically and 200 pixels horizontally). ), The edge image stored in the image storage unit 9 (the size of the edge image is 200 pixels vertically and 200 pixels horizontally) is superimposed and displayed.

  By performing the processing as described above, unlike the second embodiment, the edge image reduction processing is eliminated, so that the processing burden on the portable terminal can be reduced.

By using the image processing system 1 of the present invention, even if the image data to be displayed is raster data, it can be displayed more clearly and clearly than before when it is enlarged.

It is an example of the conceptual diagram of the whole image processing system 1 of this invention. It is an example of the block diagram of the hardware which functions the system of this invention. It is a flowchart which shows an example of the process of an image generation process. It is a flowchart which shows an example of the process of an image display process. It is an example of a normal image and original image data. It is an example of an edge image.
