Abstract
An image processor includes an encoder that performs encoding including quantization on an image signal and a controller that controls a quantization parameter in the quantization. The controller determines a quantization parameter of a currently target macroblock, based on a difference between a target amount of code for a specified number of macroblocks and an amount of code generated for a predetermined number of macroblocks processed immediately before. The controller variably sets the specified number.
