发明名称 MOVING IMAGE ENCODING DEVICE
摘要 <p>PROBLEM TO BE SOLVED: To provide a moving image encoding device which is capable of outputting encoded data having less block distortions contained in them. SOLUTION: A moving image encoding device is equipped with two image encoding processing units. One encodes the inputted moving picture and forms a reference image for the inputted moving image data. The other detects block distortions contained in the reference image, determines the size of quantizing steps on the basis of the above result so as to decrease the block distortions, carries out encoding, and outputs encoded data.</p>
