ENCODER EVALUATION METHOD, PROGRAM, AND ENCODER EVALUATION DEVICE

摘要

PROBLEM TO BE SOLVED: To evaluate whether encoded data are encoded by an optimum compression method or not.

SOLUTION: This encoder evaluation method is executed by this encoder evaluation device 1 having a processor 2, and capable of accessing to an original image data storage part 3 for storing original image data therein, and an encoded data storage part 4 for storing encoded data obtained by encoding the original image data therein. The encoder evaluation method includes processes of: reading the original image data from the original data storage part 3 by the processor 2; generating predicted image data from the original image data by a plurality of prediction methods to calculate cost on a prediction method basis; reading the encoded data from the encoded data storage part 4; and evaluating cost calculated from the original image data and cost calculated from a parameter of the encoded data.
