IMAGE DATA TRANSMITTING METHOD AND IMAGE DATA TRANSMITTING/GENERATING SYSTEM

摘要

PROBLEM TO BE SOLVED: To reduce the processing load of a network band occurring when image data are distributed to a plurality of client devices from a lecturer side terminal 1 in real time in a remote lecture and a seminar or the like by computers using the Internet.

SOLUTION: The image data of a frame successively acquiring the image data are divided into a plurality of preset areas in main body devices 1, 2. Divided image data in each divided area are stored by making them correspond to the divided areas. The image data of a frame to be inputted next are divided into a plurality of the preset areas. The divided image data in each divided area are stored by making them to correspond to the divided areas. The image data inputted first and the image data inputted next in the same divided area are compared with each other. The processing load of the band required for transmitting the image data can be reduced by making only the changed divided image data to be displayed by the client device 3 when there is a change in the image data.
