Hue adjusting method and hue adjusting device

摘要

An object of the invention is to provide a hue adjusting device and a hue adjusting method that adjust finely the hue of a color image signal. The CPU calculates an off set matrix B that is in a pair with an off set matrix A to a central matrix X when the matrix X and the off set matrix A are inputted from an operating part. Then the CPU carries out the following operation when a parameter a is inputted from the operating part.It is possible to execute matrix conversion to adjust the hue by setting a matrix coefficient of each component of the matrix X' the multiplication circuits.
