摘要

PROBLEM TO BE SOLVED: To achieve digitizing and inverse digitizing based on vision characteristics.

SOLUTION: The image information coding equipment 10 changes input image signals into a block, and performs orthogonal conversion in each block unit for digitizing. In the image information coding equipment 10, a weighting section 16 that is a component of a digitizing section 15 uses a parameter QP for specifying one sequence of numbers arranged by a specific rule according to a digitizing step size in the digitization, and carries out weighting by the addition processing of the parameter QP for each constituent of an orthogonal conversion coefficient.
