Abstract
An image processing device includes a memory device that stores a color conversion module, and one or more processors that access the memory device and execute the color conversion module to calculate a color gamut of an input image and perform color conversion of the input image by applying different color conversion matrices according to the color gamut.
Claims20
An image processing device comprising:
- a memory device;
- and
- at least one processor configured to access the memory device and execute a color conversion module to calculate a color gamut to which a color of each pixel of an input image belongs and perform color conversion of the each pixel by applying different color conversion matrices according to the color gamut.
A method of operating an image processing device, the method comprising:
- calculating a hue value of each pixel of an input image;
- calculating a color gamut to which the hue value belongs;
- calculating a color conversion matrix according to the color gamut;
- and
- performing color conversion of the each pixel using the color conversion matrix.
2 more elements
An electronic device comprising:
- an image sensor configured to acquire an image of a target;
- and
- an application processor configured to perform conversion of a Hue, Saturation, Value (HSV) domain on the image, determine a color gamut to which each pixel belongs according to a value of a phase of the HSV domain, and perform different color conversion operations for the color gamut on each pixel of the image depending on the color to which the each pixel belongs.
