INFORMATION PROCESSING DEVICE, IMAGE TRANSMISSION METHOD, AND RECORDING MEDIUM
First Claim
1. An information processing device comprising:
- an image memory that stores therein an image to be displayed on a terminal device that is connected through a network; and
a processor coupled to the image memory, wherein the processor executes a process comprising;
drawing a processing result from software into the image memory;
detecting an update area containing an update between frames in the image;
first performing still image compression on the image in the update area;
first calculating a compression ratio of still image compressed data in the update area;
identifying a high-frequency change area in which a frequency of changes between the frames in the image exceeds a predetermined frequency;
second performing moving image compression on the image in the high-frequency change area;
second calculating a compression ratio of moving image compressed data in the high-frequency change area;
first transmitting, to the terminal device, the still image compressed data in the update area and the moving image compressed data in the high-frequency change area; and
stopping the moving image compression based on the result of comparing the compression ratio of the moving image compressed data in the high-frequency change area and a compression ratio of still image compressed data in a previous update area that 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.

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.

6. An image transmission method comprising:
-
drawing, using a processor, a processing result from software into an image memory that stores therein an image to be displayed on a terminal device that is connected via a network; detecting, using the processor, an update area containing an update between frames in the image; first performing still image compression on the image in the update area; first calculating, using the processor, a compression ratio of still image compressed data in the update area; identifying, using the processor, a high-frequency change area in which a frequency of changes between the frames in the image exceeds a predetermined frequency; second performing moving image compression on the image in the high-frequency change area; second calculating, using the processor, a compression ratio of moving image compressed data in the high-frequency change area; transmitting, to the terminal device, the still image compressed data in the update area and the moving image compressed data in the high-frequency change area; and stopping, using the processor, the moving image compression based on the result of comparing the compression ratio of the moving image compressed data in the high-frequency change area and a compression ratio of still image compressed data in a previous update area that 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.
