FIELD: physics, video.

SUBSTANCE: invention relates to multiview image encoding/decoding. The technical result is increasing efficiency of encoding multiview images in which there is localised mismatch of illumination and colour between cameras, a well as reducing the amount of code. The invention provides, when dividing an encoded and decoded frame and encoding/decoding each region, generation of a prediction image not only for the processed region, but for already encoded/decoded regions adjacent to the processed region. Prediction images are generated using the same prediction method. A correction parameter is then estimated for correcting mismatch of illumination and colour from the predicted images and the decoded images of adjacent regions. An estimated correction parameter can be found even at the decoding side. Encoding is therefore unnecessary.

EFFECT: corrected prediction image is generated using estimated correction parameters in order to correct a prediction image that was generated for a processed region.
