发明名称 Image processing device image processing method, and record medium
摘要 An image processing apparatus includes a color correction table, which provides a color conversion amount according to lightness L based on a color conversion amount for white (DeltaLw, Deltauw, Deltavw), and uses this color correction table for desired color correction. The color correction table decreases the color conversion amount to approximately zero when the lightness is less than a predetermined value Lmin. Also, the color correction by the color correction table is conducted such that a color point is moved toward a direction which maintains the lightness, or such that the color point is moved toward a direction which increases the lightness.
