ABSTRACT:
A transmitting device encodes an animated image by detecting a difference between one image frame and a reference image frame, then transmits the encoded image to a receiving device by a radio line at high efficiency. The transmitting device comprises an image storing unit for storing the reference image frame, an initialization unit for initializing the image storing unit, a difference encoding unit for detecting and encoding the difference, an encoded data storing unit for storing the encoded difference, a transmitting unit for detecting an error detection code in the encoded difference, and transmitting the encoded difference together with transmission information including the error detection code to the receiving device, a receiving unit for receiving reception information from the receiving device which indicates whether the receiving device finds either OK or NG as a result of error detection check which is based on the error detection code, a reproducing unit for reproducing the encoded difference and storing it as one reference frame into the image unit when the reception information indicates OK, and a controlling unit for controlling the difference encoding unit to encode the next image frame when the reception information indicates NG, while controlling the difference encoding unit to encode the next image frame only after the reproducing unit stores a new reference image frame when the received reception information indicates OK.
