Abstract
The present disclosure relates to a tuning method and apparatus for a color gamut mapping device, in which a tuning time is shortened by automatically setting and changing parameters of a register when tuning the color gamut mapping device. A tuning method of a color gamut mapping device according to an aspect includes an initial setting operation of setting, by a test device, initial parameters in a register of a color gamut mapping device, a measuring operation of measuring, by a measuring device, chromaticity for each of a plurality of color images which are supplied from the test device and displayed on a panel of a display device through the color gamut mapping device, an automatic tuning operation of changing, by the test device, saturation parameters and hue parameters of a plurality of hue axes of the color gamut mapping device by using a result measured from the measuring device.
