Abstract
A pixel map signal is separated into block signals, each representing pixels in a pixel map block (420) in a pixel map (410). The blocks signals each contain an overlap component having pixel values representing pixels contained both by the corresponding pixel map block (420) and an adjacent block. The pixel map signal is compressed by converting the block signals into a coefficient signal of block coefficient signals, each of which represents a pixel map block (420) with the coefficients in a hybrid polynomial. When the pixel map signal is decompressed, the pixel values in the overlap component for each pixel map block (420) are averaged with the pixel values in the overlap component for the adjacent block and replaced by the averaged pixel values in the corresponding pixel map block (420) and the adjacent pixel map block (420).
