Terminal server and in the image data acquisition system, the image data acquiring method, and image data acquisition program

摘要

PROBLEM TO BE SOLVED: To realize the maintenance of cognitive information quantity for picture data in the middle of communication even when data communication quantity is changed at communicating picture data, and reading the picture data on a terminal. SOLUTION: This system is provided with a perceptive characteristic storing part 21 for storing the characteristics of a picture necessary for allowing a human being to sufficiently acknowledge the contents of information, a display region position/speed measuring part 23 and a display magnification control part 24 for acquiring operation information for the target picture of a user, a layout information storing part 61 for storing the information from those two parts and layout information related with the target picture in the server part, and a valid resolution object deciding part 25 and a reception range calculating part 26 for calculating the region of a picture to be acquired from the target picture and the resolution of each region based on these pieces of information. Then, picture operation situations such as the position or moving speed of a display region operated by the user and picture information matched with the perceptive characteristics of the user at that time are re-configured at the server side, and transmitted to a terminal.
