Image processing device, image processing method, and program

Abstract

The present technique relates to an image processing device, an image processing method and a program which can calculate a vector which is precisely predicted as a predicted motion vector of a disparity vector. A predicted motion vector generation unit 243 generates a predicted motion vector of a disparity vector which represents a disparity of a target block of an operation target of a viewpoint #2 color image C#2 different from a point of view #1 with respect to a color image C#1 of the point of view #1, from a disparity information image D#2 of the point of view #2 which has disparity information related to a disparity of each pixel of the color image C#2 of the point of view #2 as a pixel value according to a depth information use prediction standard. The present invention is applicable to, for example, generate a predicted motion vector of a disparity vector used to generate a predicted image upon encoding or decoding of a plurality of viewpoint images.

Description

technical field [0001] The present technology relates to an image processing device, an image processing method, and a program, and more specifically, to an image processing device, an image processing method, and a program that can calculate an accurately predicted motion vector as a predicted motion vector of a disparity vector Represents the disparity of a given viewpoint image relative to another viewpoint image. Background technique [0002] Encoding standards for encoding multiple viewpoint images such as 3D (dimensional) images include, for example, the MVC (Multi-View Video Coding) standard obtained by extending the AVC (Advanced Video Coding) (H.264 / AVC) standard. [0003] According to the MVC standard, an encoding target image is a color image in which a value corresponding to light from a subject is used as a pixel value, and if necessary, other viewpoint color images are referred to in addition to this viewpoint color image to a plurality of viewpoint color image...

Problems solved by technology

[0013] According to the MVC standard, although the predicted motion vector (of the disparity vector) of the target block is calculated using the disparity vectors of the blocks surrounding the target block of the color image, when the target block is in the boundary part of the foreground object, the foreground block, background block and Blocks in the part where there is occlusion exist as surrounding blocks of this target block, so the predicted motion vector of the target block calculated with these blocks causes a decrease in prediction accuracy in some cases
