Method for chromatic adaptation of images

摘要

A method for a chromatic adaptation transformation of images using temperature and tint space comprises the steps of: acquiring a red, green, blue (RGB) image using a camera (11); providing neutral RGB values for camera specific, and at least one of a selected highlight and shadow values, to produce a 3D lookup transformation table (21); calibrating the RGB image by applying the 3D lookup transformation table to produce a calibrated RGB image (22); calculating a Von Kries transform from specific temperature and tint values (14); and applying a chromatic adaptation to the calibrated RGB image using the Von Kries transform to produce a modified RGB image chromatically adapted (15), while maintaining neutral RGB values for highlight and shadow regions.
