no. 1 Embodiment approach

[0112] (Structure of the moving picture encoding device 100)

[0113] figure 1 The configuration of the moving picture encoding device 100 according to the first embodiment of the present invention is shown. The moving picture coding device 100 is a device for coding a moving picture signal in units of prediction blocks to which motion compensation prediction is performed. The coding block division, prediction block size, and prediction coding mode are determined by a high-level coding control unit. The moving picture encoding device 100 is realized by hardware such as an information processing device including a CPU (Central Processing Unit), a frame memory, a hard disk, and the like. The moving picture encoding device 100 realizes the functional constituent elements described below by the operations of the above constituent elements.

[0114] In addition, the position information of the prediction block to be processed, the prediction block size, the reference picture ind...

no. 2 Embodiment approach

Abstract

A first vector predictor candidate list generating unit generates a first motion vector predictor candidate list from motion vectors of encoded neighboring blocks to blocks to be encoded. A second vector predictor candidate list generating unit generates a second motion vector predictor candidate list from motion vectors of blocks at the same positions as the blocks to be encoded in an encoded image and neighboring blocks to the blocks at the same positions. A combination determining unit determines whether to generate a third vector predictor candidate list combining the first and second vector predictor candidate lists by comparison of a block size of the blocks to be encoded and a threshold size. A vector predictor candidate list deciding unit generates the third vector predictor candidate list from the first vector predictor candidate list.

Description

[0001] This application is based on the application number 201280012382.9, the application date is March 05, 2012, the applicant is JVC Kenwood Co., Ltd., and the invention name is "moving picture coding device, moving picture coding method and moving picture coding program, and moving picture decoding Device, moving picture decoding method and moving picture decoding program" is a divisional application. technical field [0002] The present invention relates to a technique for encoding and decoding moving pictures using motion compensation prediction, and more particularly to a technique for encoding and decoding motion vectors used in motion compensation prediction. Background technique [0003] In general video compression coding, motion compensation prediction is used. Motion compensation prediction is a technology that divides the target image into smaller blocks, uses the decoded image as a reference image, and shifts the block from the same position as the target bloc...
