COMMUNICATION DEVICE, COMMUNICATION METHOD, AND COMMUNICATION PROGRAM

摘要

A communication device includes: an image buffer (121) which stores a display image to be displayed on a display device; an update image generation unit (111a) which generates an update image for updating the display image; a difference detection unit (112) which detects a difference region expressing a region where image information is not matched between the update image and the display image; a compressed image generation unit (113) which generates a compressed image by compressing the image in the difference region; a video generation unit (114) which generates a dynamic image with a specified rate; a control unit (115) which performs control to reduce the frame rate specified for the video generation unit (114) if the difference region size is greater than a threshold value; and a transmission unit (116a) which transmits the compressed image and the dynamic image to the display device.
