Abstract
An image processing device according to an embodiment of the present disclosure may comprise at least one processor configured to: convert a first image data of a first color space to a second image data of a second color space through a gamut mapping, obtain a luminance level of the second image data, obtain a saturation correction value corresponding to the obtained luminance level, and adjust a saturation of the second image data based on the obtained saturation correction value while maintaining the obtained luminance level.
Claims20
An image processing device, comprising:
- at least one processor configured to:
- convert a first image data of a first color space to a second image data of a second color space through a gamut mapping,
- obtain a luminance level of the second image data,
- obtain a saturation correction value corresponding to the obtained luminance level, and
- adjust a saturation of the second image data based on the obtained saturation correction value while maintaining the obtained luminance level.
A method of operating an image processing device, comprising:
- converting a first image data of a first color space to a second image data of a second color space through a gamut mapping;
- obtaining a luminance level of the second image data;
- obtaining a saturation correction value corresponding to the obtained luminance level;
- and
- adjusting a saturation of the second image data based on the obtained saturation correction value while maintaining the obtained luminance level.
A non-transitory computer-readable recording medium on which a program for performing a method of operating an image processing device is recorded,
- wherein the method comprises:
- converting a first image data of a first color space to a second image data of a second color space through a gamut mapping;
- obtaining a luminance level of the second image data;
- obtaining a saturation correction value corresponding to the obtained luminance level;
- and
- adjusting a saturation of the second image data based on the obtained saturation correction value while maintaining the obtained luminance level.
