ABSTRACT:
In order to encode image signals using interframe correlation while maintaining high data compression as well as high resulting images, a motion compensated interframe prediction error is orthogonally transformed and then is subject to quantization. Thereafter, the quantized error signal undergoes inverse orthogonal transformation. In order to compensate for distortions caused by the quantization, a difference between the inversely orthogonally transformationed error signal and the original prediction error signal is quantized. By selecting the quantization characteristics, the influence or contribution of the orthogonal transformation can be controlled continuously.
