Title: Method and apparatus for coding and decoding image data

Abstract: A matching processor detects correspondence information between key frames. A judging unit detects motion vectors from the correspondence information to determine variation of a field of view between the key frames. When variation of the field of view is sufficiently large, added information is generated related to the variation of the field of view. A stream generator generates a coded data stream by incorporating the added information. An intermediate image generator (for example, at a decoding side) detects the added information and trims edges of a generated intermediate image to account for the variation in the field of view, so that an unnatural invalidated region is cut out.
