The present invention enables an efficient encoding of video data in which a prediction signal can be determined without using a motion vector. A video encoding device 100 comprises 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 reproduced image of the encoded image, a storage section 107 for storing reproduced images, a prediction generation section 108 for searching a region which is highly correlated to a reproduced image of a template region, which is adjacent to the region of the 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. |
