摘要 |
<p>It is possible to effectively encode dynamic image data by deciding a prediction signal without using a motion vector. A dynamic image encoding device (100) includes: a region division unit (101) for dividing a frame image constituting dynamic image data as an object to be encoded into a plurality of regions; an encoding unit (104) for encoding images of the respective regions; an inverse conversion unit (105) and an addition unit (106) for generating a reproduction image of the encoded image; a storage unit (107) for storing reproduced image; a prediction generation unit (108) for searching for a region of an image adjacent to the region of the image to be encoded in a predetermined positional relationship and having a high correlation with the reproduced image of the template region as a part of the reproduced image, from the reproduced image, and deciding a prediction signal according to the searched region and the positional relationship; and a subtraction unit (102) for generating a differential signal between the prediction signal and the encoding object image as a signal for encoding.</p> |
