Abstract
A method of generating metadata includes: obtaining a first image and a second image respectively having different color gamuts; obtaining at least one of information regarding a white point and information regarding the color gamut of the second image; correcting the first image based on the obtained information; and generating the metadata based on a correspondence relation between color information of the corrected first image and color information of the second image.
Claims16
A method of generating metadata, the method comprising:
- obtaining a first image and a second image respectively having different color gamuts;
- obtaining at least one of information regarding a white point of the second image and information regarding the color gamut of the second image;
- correcting the first image based on the obtained information;
- generating metadata based on a correspondence relation between color information of the corrected first image and color information of the second image;
- and
- displaying image based on the generated metadata,
- wherein the generating of the metadata comprises:
- obtaining a brightness value of at least one pixel of the first image;
- obtaining a brightness value of a pixel of the second image that corresponds to the at least one pixel of the first image;
- and
- generating the metadata based on a brightness value of a pixel of the second image that corresponds to a brightness value of each pixel of the first image.
A method of displaying a first image based on metadata, the method comprising:
- obtaining the first image and the metadata;
- obtaining at least one of information regarding a white point of a second image having a color gamut different from that of the first image, and information regarding the color gamut;
- correcting the first image based on the obtained information;
- correcting the corrected first image based on the metadata;
- and
- displaying the first image corrected based on the metadata.
A non-transitory computer-readable recording medium having recorded thereon metadata for correcting a first image, wherein the metadata comprises:
- information regarding a brightness value of a second image that corresponds to a brightness value of the first image corrected based on at least one of information regarding a white point and information regarding a color gamut of the second image;
- and
- information regarding a saturation value of the second image that corresponds to a saturation value of the corrected first image.
