摘要

The present invention provides a method for encoding a reference image, the method comprising: encoding a sequence to obtain reconstructed images of first and second reference images; Determining whether a local area of the second reference image is suitable for updating the first reference image; Determining whether the first reference image has been updated; When it is determined that the first reference image is not updated and the second reference image is suitable for updating the first reference image, the pixel value of the corresponding region or related region of the first reference image is determined by the second reference image. Substituting pixel values in the local area; And compiling to a bitstream.
