FIELD: physics.SUBSTANCE: device includes a device for computing similarity between an intra-slice region of an encoding target picture and an intra-slice region of each of previously-encoded pictures, where the similarity is an index, where the closer the images of the two different intra-slices, the higher the similarity; a device for selecting a picture having the highest similarity from among the previously-encoded pictures; and a device for determining a quantisation step used for encoding the encoding target picture, based on the similarity for the intra-slice region computed using encoding information and similarity for the region outside the intra-slice.EFFECT: high image quality during encoding.13 cl, 9 dwg |
