System-on-chip with color gamut mapping circuit, method of operating the same, and method of mapping color gamut

A system-on-chip comprising:

• ;
• an image signal processor configured to receive a raw image data from an image sensor and to process the raw image data;
• and
• a memory device configured to store a reference table comprising a conversion relationship between first pixel data of a first color gamut and second pixel data of a second color gamut,
• wherein the image signal processor comprises a color gamut mapping circuit configured to map first image data located in the first color gamut to the second color gamut based on the reference table, and configured to output second image data located in the second color gamut based on the mapping of the first image data.

A method of operating a system-on-chip, comprising:

• receiving, by an image signal processor, first image data located in a first color gamut;
• demosaicing, by the image signal processor, the first image data;
• generating, , by a color correcting circuit of the image signal processor, second image data located in a second color gamut by correcting color of the demosaiced first image data;
• converting , by a color mapping circuit of the image signal processor, the second image data to third image data by mapping the second image data to the first color gamut based on a reference table;
• and
• outputting, by the image signal processor, the third image data located in the first color gamut.
