Abstract:
The server device draws a processing result from software in an image memory, detects an update area containing an update between frames in the image, performs still image compression, and calculates the compression ratio of still image compressed data in the update area. The server device identifies a high-frequency change area, performs moving image compression, and calculates the compression ratio of moving image compressed data. The server device transmits the still image compressed data and the moving image compressed data. The server device stops the moving image compression based on the result of comparing the compression ratio of the moving image compressed data and a compression ratio of still image compressed data in a previous update area is the update area in a previous frame detected before the start of the moving image compression and has been detected at a position associated with the high-frequency change area.
