Abstract:
The image predictive encoding device  10  comprises an intra frame predictive signal generation method determination section  15  which determines, for adjacent areas comprising regenerated pixel signals and adjacent to the target area, a predictive method which is derived on the basis of data corresponding to the adjacent areas as an R mode predictive method or an L mode predictive method, an intra frame predictive signal generation section  16  which generates an intra frame predictive signal on the basis of the R mode predictive method thus determined, and a subtractor  18 , a transform section  19 , a quantization section  20 , and an entropy encoding section  25  which encode a residual signal of a pixel signal of the target area on the basis of the generated intra frame predictive signal.

Claim (Index 5):
An image prediction decoding device which divides an image into a plurality of areas, generates an intra frame predictive signal with respect to a pixel signal contained in a target area which is a processing target among the areas, and restores the pixel signal of the target area by combining a residual signal relating to the target area contained in compressed image data and the intra frame predictive signal, the image prediction decoding device comprising:\n first predictive method determination means which determines, based on processed data corresponding to adjacent areas comprising regenerated pixel signals and adjacent to the target area, a first predictive method as a predictive method for generating the intra frame predictive signal, wherein the first predictive method determination means derives the first predictive method by processing a function including adding or subtracting of a numerical constant to or from the numerical value relating to predictive methods corresponding to the adjacent areas; predictive method deriving means which extracts a relative predictive method which is relative information identifying the predictive method relating to the target area from the compressed image data and derives a second predictive method for the target area on the basis of the first predictive method and the relative predictive method; predictive signal generation means which generates the intra frame predictive signal on the basis of the second predictive method derived by the predictive method deriving means; restoration means which extracts a residual signal relating to the target area from the compressed image data to restore a regenerated residual signal; and image restoration means which restores the pixel signal of the target area by combining the intra frame predictive signal and the regenerated residual signal restored by the restoration means.
