Abstract
A quantization control apparatus provided in a video encoding apparatus which utilizes intra slices. The quantization control apparatus includes a similarity computation device that computes 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 determined such that the closer the images of the two different intra slices, the higher the similarity; a picture selection device that selects a picture having the highest similarity from among the previously-encoded pictures, based on the similarity computed by the similarity computation device; and a quantization step determination device that determines a quantization step used for encoding the encoding target picture, based on encoding information for the picture selected by the picture selection device.
