IMAGE PROCESSING DEVICE

摘要

Provided is an image processing device which enables a reduction in delay amount compared to when the code amount is controlled GOP by GOP or frame by frame. A control unit (3) comprises a first processing unit (11) which finds the generated code amount used for an immediately preceding first predetermined number of macroblocks, a second processing unit (12) which, on the basis of the target code amount for a second predetermined number or less of macroblocks, the second predetermined number being less than the total number of macroblocks included in one frame, and the generated code amount found by the first processing unit (11), finds a permissible code amount usable for an immediately subsequent third predetermined number of macroblocks including a macroblock to be processed at present, a third processing unit (13) which finds an expected code amount expected to be used for a third predetermined number of macroblocks, and a fourth processing unit (14) which, on the basis of the permissible code amount found by the second processing unit (12) and the expected code amount found by the third processing unit (13), sets a quantization parameter for the macroblock to be processed at present.
