Abstract
The invention provides encoded moving image data having good image quality even in a scene having a high difficulty level. A unit counts a number of pictures to determine a break between scenes. A unit encodes block by block in an inputted picture. A unit calculates a block distortion between a decoded picture and a picture before being encoded. A unit calculates a surplus encoded data amount with respect to an encoded data amount equally allocated to each scene from the encoded data amount of each picture and a preset sequence target bit rate. A target encoded data amount is calculated based on an average block distortion of a scene and the surplus encoded data amount. The encoded data amount of the first picture of a scene is compared with a threshold, and the initial parameter is corrected to determine the parameter for encoding the second and subsequent pictures.
