Abstract
The image data transferring apparatus of this invention determines that the change in the image is very small when a change in the image is not detected during a given time period, for example, and generates transmission data which causes image data displaying a full color image of, for example, 24 bits per pixel to be displayed in the receiving side in a relatively small number of frames in a unit time for transmission. Conversely, the image data transferring apparatus transmits reduced color data which is reduced from 24 bits per pixel to 4 bits per pixel in a relatively large number of frames in a unit time to the receiving side when it is determined that many changes are included in the image.
