Raster data is so-called bitmap data, and is a data format in which an image is expressed by specifying what color is displayed for each pixel.

[0006] When such raster data is enlarged and displayed, the enlarged image data is neatly displayed. Do not show. 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 four pixels in the enlarged image data, which is a total of two vertical pixels and two horizontal pixels. Because it will be. For this reason, the outline becomes a jagged image and is not displayed neatly.

BEST MODE FOR CARRYING OUT THE INVENTION

The 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 on 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. It should be noted that the image display system 3 is a power that exerts a greater effect when functioning on a device having a small display device 22 such as a portable terminal. Even if the display device 22 is not as small as a normal computer terminal, the image display system 3 is effective. The fruit can be demonstrated.

A conceptual diagram of the image processing system 1 is shown in FIG. In addition, a computer terminal that realizes the image generation system 2, a portable terminal or a computer terminal that realizes the image display system 3. Figure 2 shows an example of the hardware configuration.

[0036] The computer terminal or the 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 a processing result of the arithmetic device 20. And a communication device 24 that transmits and receives information stored in the storage device 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 means (program or module) for executing the processing into the arithmetic unit 20. When each function uses the information stored in the storage device 21 in its processing, each function reads the corresponding information from the storage device 21 and uses the read information for processing in the arithmetic device 20 as appropriate. In addition, 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.

[0037] Each means in the present invention is only logically distinguished in its function, and may be physically or effectively 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 also includes a download data reading unit 8, an image storage unit 9, and a display processing unit 10.

[0039] The image generation system 2 is a system for generating data (download data) to be downloaded to the image display system 3 based on the original image data. It is a system that downloads from the server and displays the normal image (described later) in the downloaded data.

The image reading unit 4 reads original image data having raster data power into the image generation system 2. For example, Fig. 5 (b) shows an example of original image data.

[0041] The original image data read here is reduced to a predetermined size (vertical and horizontal size) by a normal image generation unit 6 to be described later in order to be displayed by the image display system 3. An example of image data with reduced size (normal image) is shown in Fig. 5 (a).

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. Figure 6 shows an example of an edge image. In Fig. 6, part of the original image data (key Data obtained by extracting all contour pixels for the right side of the lacto) as an edge image The edge image may be obtained by extracting all or part of the contour pixels of the original image data. 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 original image data. For example, the original image data can be divided into right and left sides, and two edge images can be generated: a right edge image and a left edge image!

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. . In this way, 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. 5 (a).

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 amount of data is not large. In addition, the amount of data is not large because the edge image is information on the pixels of the contour of the original image data. 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 manage them separately.

[0045] In the case of the above-described 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 are the 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.

[0047] 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. The image is stored in the image storage unit 9.

[0048] In the image storage unit 9, the download data is converted into a composition for realizing the image display system 3. Stored in the storage device 21 of the data terminal or portable terminal.

[0049] The display processing unit 10 first displays a normal image on the display device 22 of the computer terminal or portable terminal that implements the image display system 3, and receives the normal image enlargement request. Is enlarged to a predetermined size and the edge image is superimposed on it. Fig. 7 (a) shows a case where the normal image is enlarged and Fig. 7 (b) shows a case where the edge image is superimposed on the normal image shown in Fig. 7 (a).

Example 1

Next, the processing process of the present invention will be described with reference to the flowcharts of FIGS. 3 and 4. In the following description, a case where the image display system 3 is realized by a mobile terminal will be described. However, as described above, this does not prevent the image display system 3 from being realized by a computer terminal.

[0051] Although the case of a comic as an image to be 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 the original image of the image to be distributed to the user (S100).

[0053] When the original image data is read by the image reading unit 4, the edge image extraction unit 5 extracts the pixels constituting the contour from the original image data (S110). On average, when the edge image is extracted, the inventor's research has shown that the original image power is less than 10% of the original image data, 75% more than the compression of normal image data. This also improves the compression ratio.

[0054] Further, the original image data read by the image reading unit 4 is reduced to a predetermined size designated by the portable terminal, thereby generating a normal image (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, edge image, and force 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).

[0056] By performing the above processing, data to be downloaded to the mobile terminal can be generated. [0057] 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 like via the network such as the Internet by performing a predetermined operation from the mobile terminal, or A download data acquisition request is made from a predetermined image server, and the storage device 21 of the image generation system 2 or the predetermined image server that receives the request transmits the download data to the mobile terminal. The downloaded 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.

[0059] 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 mobile terminal.

[0060] The user's ability to view this normal image When the user wants to enlarge and display the normal image, the display processing unit 10 accepts an enlargement request by inputting a predetermined operation from the input device 23 of the mobile terminal ( S220).

[0061] 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 mobile terminal (S230). At this time, the size of the normal image should be the same size as the original image data! Fig. 7 (a) shows the enlarged normal image.

[0062] 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. 7 (b).

[0063] In this way, by associating the edge image with the normal image and superimposing and displaying the enlarged image together with the normal image, the image is clearer than the simple enlarged display of the normal image with a small amount of data. Can be displayed. Also, since no vector data is used, it is not necessary to convert raster data to vector data when generating an image, and the burden of image generation can be reduced.

Example 2

[0064] Next, in the above-described embodiment, the size when the normal image is enlarged is displayed. The case where the size of the edge image is not the same will be described. In this case, the edge image power cannot be displayed neatly 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.

[0065] For example, assume that the size of the original image data (edge image) is 400 pixels long and 400 pixels wide, and the size of the normal image is 100 pixels long and 100 pixels wide. Assume that a request to enlarge the normal image to 2 times is received.

[0066] In this case, since the size of the enlarged normal image is displayed with 200 pixels in the vertical direction and 200 pixels in the horizontal direction, the display processing unit 10 sets the size of the edge image stored in the image storage unit 9 in the vertical and horizontal directions. Reduce by 50%. Then, the size of the reduced edge image is 200 pixels vertically and 200 pixels wide, the size of the enlarged normal image and the size of the reduced edge image are the same size, and the reduced edge image is superimposed on the enlarged normal image. Will be displayed neatly.

[0067] The display processing unit 10 may automatically reduce the edge image to the same size and display it in accordance with the enlarged size of the normal image.

Example 3

[0068] 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. When the enlargement size of the normal image is determined in advance, the original image data can be read by the edge image extraction unit 5 of the image generation system 2 rather than providing the display processing unit 10 with a reduced display of the edge image. When extracting the outline pixels, it is good to generate the edge image after reducing it to a predetermined size (a size that matches the enlarged size of the normal image)!

[0069] For example, as described above, for example, the original image data (edge image) size is 400 pixels long and 400 pixels wide, and the normal image size is 100 pixels long and 100 pixels wide. Is the size of 200 pixels vertically and 200 pixels horizontally.

[0070] In this case, the edge image extraction unit 5 reduces the image data composed of the contour pixels extracted from the original image data column by 50% in the vertical and horizontal directions, The image is generated. Then, the size of the generated edge image is 200 pixels vertically and 200 pixels horizontally.

[0071] The download data generation unit 7 associates the normal image generated by the normal image generation unit 6 with the edge image to obtain download data.

[0072] 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, so that the enlarged normal image (the size of the enlarged normal image is 200 pixels vertically). 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 on the 200 pixels horizontally.

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 mobile terminal can be reduced.

Industrial applicability

[0074] 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.
