PROBLEM TO BE SOLVED: To efficiently utilize a buffer memory and to achieve further encoding efficiency improvement also by determining the number of reproduced images capable of being stored in the image buffer memory in accordance with a frame size of the reproduced images.SOLUTION: A moving image prediction decoding method according to the invention includes: an input step for inputting encoded data indicating compressed image data including information concerned with a target image frame size, the maximum number of reproduced images capable of being stored and a maximum frame size; a decoding step for restoring reproduced images and the information concerned with the target image frame size, the maximum number of reproduced images capable of being stored and the maximum frame size; and an image storage step for storing the reproduced images. In the method, the maximum number of reproduced images capable of being stored in a frame memory is determined as equal, two times or four times on the basis of relation between a maximum frame size of images and a frame size of an input image.SELECTED DRAWING: Figure 5 |
