2 is a block diagram of a high quality image service system according to the present invention. As shown, the high definition image service system 100 includes an interactive partial query (IPQ) server 20 for storing and providing a large amount of high definition original digital images, the network 30 and the mobile communication terminal 40. ) Here, the network 30 has the same configuration as the network 2 of FIG. 1.

In detail, the IPQ server 20 reads an original digital image and has a different number of pixels at different magnifications, and is composed of a plurality of image layers divided into a plurality of image tiles. That is, an IPQ authoring program 21 for generating segmented and layered image data (disclosed in detail in FIGS. 3 and 4) and a database for storing the generated image data (and / or image layers and / or image tiles). At least (22).

The mobile communication terminal 40 is similar to the mobile communication terminal 40 of FIG. 1, but additionally includes an IPQ browser for requesting only a part of image data (or image layer or image tile). As a result, the mobile communication terminal 40 and the IPQ server 20 provide an image to the user through a partial access method that transmits only some image tiles among the entire image or layer. Description of this is disclosed below.

Here, the interaction part request (IPQ) requests only the part (image tile) to be displayed on the display of the mobile communication terminal 40 by the interaction between the IPQ server 20 and the mobile communication terminal 40, and thus the IPQ server It refers to a service of the method 20 transmits only the requested portion (image tile) to the mobile communication terminal (40).

3 is a schematic diagram of an embodiment of image data.

As shown, the image data 60 consists of image layers 62, 64, 66 having different pixel counts according to different magnifications from the same original digital image. The image layers 62, 64, and 66 may be 1/4, 1/3, 1/2, 1 times the size of the original digital image, depending on the display size of the mobile communication terminal 40 or the original. Depending on the quality of the digital image, it may have more image layers.

The number of such image layers 62, 64, and 66 refers to steps in which a user may enlarge, reduce, or move an image displayed on the display of the mobile communication terminal 40. In the image data 60 according to FIG. 3, the user can make one reduction (image layer 62) and one magnification (image layer 66) if the original digital image corresponds to the image layer 64. do. These image layers 62, 64 and 66 correspond to hierarchical data of the original digital image.

Next, each image layer 62, 64, 66 is divided into a plurality of image tiles A11 to A44, B11 to B44, and C11 to C44. The image layers 62, 64, and 66 shown in FIG. 3 are all composed of 16 image tiles, but in other embodiments, image layers divided into different numbers of image tiles may be used. The size of the image tiles of each image layer 62, 64, 66 is determined according to the magnification of the image layer 62, 64, 66, and the image tiles in the same image layer 62, 64, 66 have the same size. . Here, the location information of the image tile includes an image layer (62, 64, 66) including each image tile and the arrangement in the image layer (62, 64, 66), for example, image layer ( The location information of the image tile in the first row and the first column of the row 62) is composed of 'A11' as shown, including 'A' meaning the image layer 62 and '11' meaning one row and one column. .

4 is a flowchart for forming image data of an IPQ authoring program.

As shown, the IPQ authoring program 21 generates image layers 62, 64, 66 having different pixel counts according to different magnifications from the original digital image in step S41.

The generated image data is transmitted to the database 22 and stored.

5A and 5B are embodiments of various color tables.

The color table shown in FIG. 5A is a basic 256 color table, and the color table shown in FIG. 5B is a modified 256 color table.

This modified 256 color table is a table made by selecting 256 color colors from a higher quality color table, for example, from a 60,000 color table. Thus, the modified 256 color table is capable of multiple modifications. When the IPQ authoring program 21 generates image data of these basic 256 color tables and / or modified 256 color tables, it is possible to apply different or identical tables to each image tile. For high-definition service of 16-bit or higher that could not be serviced due to the low speed of mobile communication environment, it is possible to realize high-definition similar to 16-bit using 8-bit by using individual color table (that is, transformed color table) of image tiles. It becomes possible.

Applying such singular or plural modified 256-color tables to image tiles or pixels, it is possible to represent more colors than the basic color table has. Thus, the larger the original digital image size, and the larger the number of appropriately sized image tiles, the wider the color gamut. This method reduces the transmission size of the image file and at the same time has a high color reproduction method.

Here, the IPQ server 20 stores image data according to the basic color table and / or the modified color table, respectively, and displays the display performance of the mobile communication terminal 40 that wants the image service (that is, the image to which the modified color table is applied). In order to display the data (tile), at least, for example, 60,000 color tables should be able to be displayed, it is possible to serve the image data (tile) to which the basic color table is applied or the image data to which the modified color table is applied. The display performance of the mobile communication terminal 40 is obtained by the IPQ server 20 from the terminal information transmitted by the mobile communication terminal 40 after the IPQ server 20 is connected to the mobile communication terminal 40. do.

6 is a block diagram of a mobile communication terminal according to the present invention. As shown in FIG. 6, the mobile communication terminal 40 stores a communication interface 41 communicating with the IPQ server 20 via the network 30, and a video storing image tiles received from the IPQ server 20. A display unit 43 including a buffer 42, a data display area (not shown) for displaying at least one image tile, and a predetermined user interface (not shown); Control means 45 controlling the input unit 44, the communication interface 41, the video buffer 42, the display unit 43, and the input unit 44, and processing the request and reception of image data (or image tiles). And an IPQ browser 46 which is controlled by the control means 45 and calculates and provides the position information of the image layer or image tile requested by the user input or by a predetermined prediction to the control means 45. do.

Referring to the operation of the components of the mobile communication terminal 40, first, when a user requests an image service for a digital image through the input unit 44, the control means 45 is associated with the image service request according to the request. An image request message is generated and transmitted to the network 30 via the communication interface 41, and the IPQ server 20 transmits at least one or more image tiles of the at least one digital image in response to the message.

The control means 45 receives the image tile through the communication interface 41, stores the received image tile in the video buffer 42, reads out the decompressed image tile, and decompresses the display unit 43. In the data display area. A more detailed description of the IPQ service is described below with reference to FIGS. 7A-7C.

7A to 7C are schematic diagrams for describing an IPQ service.

Initially, when the mobile communication terminal 40 requests the digital image service to the IPQ server 20, the IPQ server 20 is all image tiles (A11 to A44) of the image layer 62 of FIG. (Assuming that the layer 62 can be displayed in the data display area), and the control means 45 stores it in the video buffer 42. Subsequently, the control means 45 decompresses the image tiles A11 to A44 and displays them in the data display area. At this time, the IPQ server 20 provides the mobile communication terminal 40 with information such as the number of layers of the original digital image, the number and arrangement of image tiles, and the necessary information by the IPQ browser. The location information of the image tile may be calculated.

Next, in the case of an image magnification service, that is, when the user wants to enlarge the digital image, the control means 45 receives an image magnification request from the input unit 44 and uses the IPQ browser ( 46, the IPQ browser 46, based on the image tile currently stored in the video buffer 42 and / or the image tile currently displayed in the data display area, displays the image layer 62 of this stored or displayed image tile. Position information (e.g., 'A') of the image tile is read by the positional information (e.g., 'A11' to 'A44) of the image tile. , 'B') is calculated and provided to the control means 45. The control means 45 generates an image request message including the calculated position information of the image layer 64 or image tile and transmits it to the IPQ server 20.

The IPQ server 20 receives an image request message, reads the stored image layer 64 from the DB 22, and adjusts the size of the display unit 43 of the mobile communication terminal 40 or the size of the data display area. In consideration of this, as shown in FIG. 7A, only the image tiles B11, B12, B21, and B22 in the corresponding area S1 or only four image tiles are read and transmitted in the response message.

Therefore, the mobile communication terminal 40 stores and displays only the received image tiles B11, B12, B21, and B22. However, at this time, the control means 45 may delete the image tiles A11 to A44 of the previously stored and displayed image layer 62.

At this time, the control means 45 can predict the image enlargement request from the user, since the digital image displayed initially is small even before the image enlargement request from the user is received. In response to this prediction, the control means 45 causes the IPQ browser 46 to calculate the position information of the image layer 64 of a larger magnification, and requests the IPQ server 20 to receive the received image layer 64. Image tiles B11, B12, B21, and B22 may be stored in the video buffer 42, and read and displayed immediately upon request for image enlargement from the user.

The image reduction service is similar to the image enlargement service, and consists of a request and response for an image layer having a lower magnification than an image layer of an image tile currently stored or displayed.

Next, in the case of the image moving service, that is, the user requests another image tile in the same image layer 64, when the control means 45 receives a request for the image moving service from the input unit 44, The IPQ browser 46 causes the position information of the image tile corresponding to the user request to be calculated. As shown in FIG. 7B, the area S2 (S12 (image tiles B21 and B22)) and S22 (image tile) in the area S1 of the image tiles B11, B12, B21, and B22 currently displayed by the user. (B31, B32))), the control means 45 causes the IPQ browser 44 to calculate the position information of the image tile for the area S22, and the calculated position information B31, B32. ) Generates an image request message including the) and transmits it to the IPQ server 20. At this time, the control means 45 may make an image request for the image tiles B31 and B32 which are not stored in the video buffer 42 or not displayed in the data display area as described above, An image request may be made for the image tiles B21, B22, B31, and B32 corresponding to S2). However, if the former is used, data traffic can be reduced. The IPQ server 20 reads the image tiles B31 and B32 from the DB 22 and transmits them to the mobile communication terminal 40.

Even in the case of the image moving service here, the control means 45 predicts an image moving request from the user, so that the image tiles B13 and B23 adjacent to the area S1 of the currently displayed image tiles B11, B12, B21 and B22. After the IPQ browser 46 calculates the location information on the B31 and B32, the image request message is received from the IPQ server 20 and stored in the video buffer 42. You can also decompress it when you have an input to display it in the data display area.

FIG. 7C illustrates an image tile C11 in an image layer 66 received by the mobile communication terminal 40 from the IPQ server 20 when the user requests an image enlargement when the area S1 of FIG. 7A is displayed. To show.
