IMAGE PROCESSING CONTROL DEVICE AND METHOD

摘要

PROBLEM TO BE SOLVED: To improve the accuracy of reducing encoded block distortion.SOLUTION: An adjacent pixel difference absolute value phase-based total value calculation unit 121 calculates a difference value of adjacent pixels with each other to calculate the total values for every phase. An encoded distortion parameter calculating unit 122 uses the adjacent pixel difference absolute value phase-based total values calculated by the adjacent pixel difference absolute value phase-based total value calculation unit 121 to calculate encoded distortion parameters being various parameters about encoded distortion. A control unit 112 generates a control signal for controlling an image processing unit 102 according to the value of the encoded distortion parameters calculated by the encoded distortion parameter calculating unit 122 to control the operation of the image processing unit 102 by supplying the control signal to the image processing unit 102. The invention is applicable, for example, to an image processor.
