Abstract
An image processor that achieves reduction in delay amount, in comparison with code amount control GOP by GOP or frame by frame. The controller includes a first processing unit that obtains a generated amount of code used for a first predetermined number of immediately preceding macroblocks, a second processing unit that obtains an allowable amount of code available for a third predetermined number of immediately subsequent macroblocks including a currently target macroblock, based on a target amount of code for not more than a second predetermined number of macroblocks less than a total number of macroblocks included in one frame, and the generated amount of code obtained by the first processing unit, a third processing unit that obtains an expected amount of code expected to be used for the third predetermined number of macroblocks, and a fourth processing unit that sets a quantization parameter of a currently target macroblock, based on the allowable amount of code obtained by the second processing unit and the expected amount of code obtained by the third processing unit.
