Abstract
An image processor includes an encoder that performs encoding including quantization on an image signal and a controller that controls a quantization parameter for quantization. The controller determines a quantization parameter of a currently target macroblock as an increase or decrease from a reference value, and determines the increase or decrease based on a difference between a target amount of code for a predetermined number of macroblocks fewer than a total number of macroblocks within one frame and a generated amount of code of the predetermined number of macroblocks processed immediately before. The controller can further determine the increase or decrease, based on pixel information of the currently target macroblock such as an activity evaluation value.
