<p><P>PROBLEM TO BE SOLVED: To efficiently encode video data by determining a prediction signal without using a motion vector. <P>SOLUTION: A video encoding device 100 includes: a region division section 101 for dividing a frame image constituting video data into a plurality of regions as encoding target regions; an encoding section 104 for encoding an image of each region; an inverse transformation section 105 and an addition section 106 for generating a reproduced image of the encoded image; a storage section 107 for storing the reproduced image; a prediction generation section 108 for searching for an image region which is highly correlated to a reproduced image of a template region, which is adjacent to a region of an encoding target image in a predetermined positional relationship and is a part of the reproduced image, from the reproduced image, and determining a prediction signal based on the searched region and the above-mentioned positional relationship; and a subtraction section 102 for generating a difference signal between the prediction signal and the encoding target image as a signal for encoding. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
