摘要： 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.

摘要： A video encoding device, which uses intra encoding and inter encoding with motion compensation with respect to an input video signal, includes a determination unit which determines whether the input video signal to be encoded corresponds to a stationary region, a region having minute motion, or a region having normal motion, a first encoding unit which performs inter encoding of a motion vector (0, 0) with respect to a region determined as a stationary region by the determination unit, a second encoding unit which performs motion search and inter encoding in a limited search range with respect to a region determined as a region having minute motion by the determination unit, and a third encoding unit which performs motion search and inter encoding in a normal search range with respect to a region determined as a region having normal motion by the determination unit.
