Color correcting method and apparatus and a system incorporating the same

摘要

A color correcting apparatus and method convert a first color signal of a first format into a second color signal of a second format using a conversion matrix. The conversion matrix is obtained based on an achromatic color component conversion matrix and a chromatic color component conversion matrix representing chromacity and achromacity of an imaging device supplying the first color signal. Then, the second color signal is inversely converted into a third color signal of a third format. The third format is a format used by an image output unit. The inverse converting is performed using an inverse conversion matrix. The inverse conversion matrix is obtained based on an inverse of a conversion matrix associated with the image output unit, and the conversion matrix associated with the image output unit is obtained based on an achromatic color component conversion matrix and chromatic color component conversion matrix representing chromacity and achromacity of the image output unit. Furthermore, the color correcting apparatus and method may be employed in an imaging system.
