PURPOSE: To obtain an operation estimating device, that decides a motion vector as a position where final data quantity is reduced, even when a motion vector is undergone variable length coding and takes variable length coding into consideration. CONSTITUTION: An average error means 100 estimates an operation and calculates an average error of pixel data of a reference image and a current image. An operation vector setting means 200 sets horizontal/vertical displacement, where the average error that is outputted from an average error calculating means 100 and final transmission data quantity, to which a quantization step size that is produced by the repletion degree of a buffer is applied and which has undergone variable length coding become minimum by an operation vector. |
