摘要

An image prediction encoding device (10) includes an in-screen prediction signal generation method decision unit (15) for deciding a prediction method induced according to data corresponding to an adjacent region as an R mode prediction method or an L mode prediction method for the adjacent region formed by a reproduced pixel signal adjacent to an object region; an in-screen prediction signal generation unit (16) for generating an in-screen prediction signal according to the decided R mode prediction method; and a subtractor (18), a conversion unit (19), a quantization unit (20), and an entropy encoding unit (25) for encoding a residual signal of the object region against the pixel signal according to the generated in-screen prediction signal.
