ABSTRACT:
A moving picture encoding system. There is provided a moving picture encoding system and method for changing the resolution of an original picture that is an object of encoding using a proper criterion, and encoding the picture while preventing deterioration of picture quality. A motion prediction/calculation means provides information of an error in prediction or of randomness of a motion vector which is calculated in the course of or as a result of motion prediction. A resolution determination means determines a resolution for the input picture to be encoded using the information. The input picture is converted into a picture having the determined resolution, and the picture resulting from the conversion is encoded and output.
