ABSTRACT:
An image signal processing apparatus for quantizing an inputted moving image signal according to a quantization step so that a code amount of one frame becomes a target code amount, and for variable-length-coding the quantized moving image signal, in which a minimum value of the quantization step is determined for each frame, and the quantization step is determined so as not to be less than the minimum value.
