ABSTRACT:
A picture signal processing system includes an orthogonal transformer which performs an orthogonal transformation upon a group of picture signals to generate transformed coefficients G. A quantizer divides each of the transformed coefficients G by a quantization factor C determined by ##EQU1## where A and B are integers, and S is a sign. The quantizer generates a quantization coefficient G/C for each of the transformed coefficients G. Then, an encoder encodes each of the quantization coefficients G/C to generate compressed signals of the picture signals.
