METHOD OF ENCODING VIDEO SIGNAL AND METHOD OF DECODING, APPARATUS FOR REALISING SAID METHODS AND DATA MEDIA STORING PROGRAMMES FOR REALISING SAID METHODS

摘要

FIELD: information technology.;SUBSTANCE: apparatus for encoding video signal generates a synthetic image for a camera used to obtain a target encoding image using an already encoded reference image of the camera, having a viewpoint different from the viewpoint of the camera used to obtain the target encoding image, and information on disparity between the reference image of the camera and the target encoding image, thereby encoding the target encoding image. A predicted image is formed for a difference image between the input image of the target encoding region which needs to be encoded and the formed synthetic image, and a predicted image is formed for the target encoding region, which is represented by the sum of the predicted difference image and the synthetic image for the target encoding region. The prediction residue is encoded, represented by the difference between the predicted image for the target encoding region and the target encoding image in the target encoding region.;EFFECT: providing a vide encoder and decoder in which there is no need to process different bit depths by forming a predicted image for the input image.;28 cl, 14 dwg
