VIDEO ENCODER, VIDEO DECODER, VIDEO PROCESSING SYSTEM, VIDEO ENCODING METHOD, VIDEO DECODING METHOD, AND PROGRAM
Document Type and Number:
Japanese Patent JP2016127372
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To enhance the coding efficiency of a video of a plurality of view points of different perspective.SOLUTION: A video encoder 1 includes a first encoder 10, a second encoder 20, and an inter-view processing unit 30. The first encoder 10 encodes the original image SIG1 of expansion point of view, and outputs a bit stream SIG6 of expansion point of view. The second encoder 20 encodes the original image SIG2 of reference point of view, and outputs a bit stream SIG7 of reference point of view. The inter-view processing unit 30 performs projective transformation and illumination compensation of a local decoded image SIG3 depending on the relationship of reference point of view and expansion point of view, and generates a local decoded image SIG4 after conversion of the reference point of view, so that the first encoder 10 can use this local decoded image SIG4 after conversion of the reference point of view as a reference image, when performing inter-prediction.SELECTED DRAWING: Figure 2
