摘要：
In an image processing method of sequentially loading, compressing, and transmitting images to thereby display the images, there is provided the image processing method capable of preventing the images from degradation while keeping the responsibility until the image is displayed. When a changed region is determined to be present, the image is compressed using a method with a high compression ratio, while when there is no changed region and a predetermined period of time elapses, the image is determined to be static to thereby be compressed using a method with a low compression ratio and very little distortion.
