Abstract:
1. An image signal processing apparatus comprising: a rearranging unit configured to rearrange pictures of an input moving image signal in an order of predetermined picture types; a quantization unit configured to set a quantization value; and to quantize the moving image signal output from said rearranging unit according to the set quantization value, said quantization unit setting said quantization value for each picture of the rearranged pictures so as not to be less than a minimum value fixedly determined for each picture; a coding unit configured to variable-length-encode the moving image signal quantized by said quantization unit; and a control unit configured to fixedly determine the minimum values of said quantization value based on the picture type in accordance with the picture type corresponding to the order of the pictures rearranged by said rearranging unit.
