摘要： In a color correction method of performing correction by dividing the color plane into a plurality of areas, and correcting the color according to different methods for each divided area, color shifts generated in converting color signal vectors are prevented from arising. When determining which area of the color signal plane divided by area boundary lines passing through the origin of the color signal plane includes the input color signal vector, and correcting the input color signal vector by converting the input color signal vector using a correction matrix having been designated in advance for the area determined to include the input color signal vector, a correction matrix including a component for performing parallel translation and a component for performing linear transformation is used as a correction matrix.
