Abstract
The invention provides a linear matrix circuit which can control linear conversion of color reproduction with a comparatively small number of parameters, which conform with a feeling of a human being, by means of a circuit of a comparatively small scale using a comparatively simple method. The linear matrix circuit performs linear conversion of color reproduction for use with an image processing apparatus which separates a video signal into three primary color components of red, green and blue, and includes a coefficient conversion section for introducing six coefficients required for the linear conversion of color reproduction from two control parameters.
