PROBLEM TO BE SOLVED: To provide a data structure for displaying a high-definition image at high speed within fixed time by dividing/compressing an image on a server into matrix and storing it as the several stages of enciphered resolution data. SOLUTION: This device is composed of a server 1, auxiliary storage device 2, input device 3, display device 4, client 5, image expanding parts 6 and 8, image managing part 7, image display part 9 and communication line 10. Besides, both the server 1 and the client 5 are provided with the image expanding part 6 or 8, a means for judging dynamically the CPU load of the server 1/client 5 is provided and a means is provided for segmenting and recompressing only one part of blocks required for display when expanding processing is performed at the server 1. Thus, the image to be stored in the server 1 is previously divided into the multiple hierarchies of resolution data for each image and further, the data divided into matrix are enciphered and prepared as an archieve file collected in a library format. |
