摘要：A color correcting apparatus and method convert a first color signal of a firstformat into a second color signal of a second format using a conversion matrix. Theconversion matrix is obtained based on an achromatic color component conversion matrixand a chromatic color component conversion matrix representing chromacity andachromacity of an imaging device supplying the first color signal. Then, the second colorsignal is inversely converted into a third color signal of a third format. The third format isa format used by an image output unit. The inverse converting is performed using aninverse conversion matrix. The inverse conversion matrix is obtained based on an inverseof a conversion matrix associated with the image output unit, and the conversion matrixassociated with the image output unit is obtained based on an achromatic colorcomponent conversion matrix and chromatic color component conversion matrixrepresenting chromacity and achromacity of the image output unit. Furthermore, thecolor correcting apparatus and method may be employed in an imaging system.
