Abstract
An optimal interpolation frame is achieved by estimating optimal motion vectors both for a coding process and an interpolation frame generating process. A video codec apparatus coding and decoding a video and generating an interpolation frame in the decoding includes a motion vector estimation unit calculating an evaluation value to evaluate a correlation between images using a calculating formula and estimates a motion vector using the evaluation value, a motion vector coding unit coding video data using the motion vector and outputs a coded stream, video decoding unit decoding the coded stream and outputs video frames generated by the decoding, a frame interpolation unit generating interpolation frame using the motion vector, a cost calculating formula selecting unit selecting the calculation method depending upon whether the coding by the motion vector coding unit or the generating an interpolation frame by the frame interpolation unit is being executed.
