摘要： In picture encoding that generates prediction pictures from picture information of frames previously encoded and encodes picture information for each area, the encoding efficiency is improved. A plurality of motion vector candidates are stored in advance in a motion vector storage memory (107). A motion vector selection section (109) selects a motion vector to be used from the plurality of motion vectors stored in advance in the motion vector storage memory (107). A prediction picture generation section (104) generates a prediction picture from a reference picture using the selected motion vector. A differential encoding section (103) encodes a differential between the picture information of the present area and the prediction picture. A motion vector designation encoding section (110) encodes information that designates the motion vector selected by the motion vector selection section (109).

摘要： A video encoding apparatus divides each frame which forms an encoding target video into a plurality of processing regions, each processing region being subjected to predictive encoding, where a basic reference region associated with each processing region as an encoding target image is set. A first reference prediction region and a second reference prediction region, which are reference regions associated with the basic reference region, are set. Based on a first reference predicted image and a second reference predicted image which correspond to the reference prediction regions, weighting coefficients assigned to individual small regions are set. A first prediction region and a second prediction region, which are reference regions for the encoding target image, are set. A predicted image is generated based on the weighting coefficients, and a first primary-predicted image and a second primary-predicted image which are obtained based on the first and second prediction regions.

摘要： High coding efficiency is achieved when disparity-compensated prediction is performed on an encoding (decoding) target picture using depth information representing a three-dimensional position of an object in a reference picture. A correspondence point on the reference picture is set for each pixel of the encoding target picture. Object depth information which is depth information for a pixel at an integer pixel position on the encoding target picture indicated by the correspondence point is set. A tap length for pixel interpolation is determined using reference picture depth information for a pixel at an integer pixel position or an integer pixel position around a fractional pixel position on the reference picture indicated by the correspondence point and the object depth information. A pixel value at the integer pixel position or the fractional pixel position on the reference picture indicated by the correspondence point is generated using an interpolation filter in accordance with the tap length. Inter-view picture prediction is performed by setting the generated pixel value as a predicted value of the pixel at the integer pixel position on the encoding target picture indicated by the correspondence point.
