Abstract
A method to enable modification of color characteristics of an image. In the method, an image, defined in a first color space, is transformed to a second color space; and display of the transformed image is controlled. A color characteristic of the transformed image is modified using a rule defined in the second color space in response to a user input, and display of the modified transformed image is controlled.
Claims20
A method comprising:
- transforming, by a system including a processor, an image, defined in a first color space, to a second color space;
- controlling, by the system, display of the transformed image;
- generating, by the system, a rule defined in the second color space using a color characteristic setting adjusted by a user input, the rule including functions representing respective colors of the second color space, the functions computed based on the color characteristic setting adjusted by the user input;
- modifying, by the system, a color characteristic of the transformed image using the rule defined in the second color space, wherein modifying the color characteristic comprises applying the functions to respective color values of the transformed image;
- and
- controlling, by the system, display of the modified transformed image.
Apparatus comprising:
- a controller implemented at least in hardware to:
- transform an image, defined in a first color space, to a second color space;
- control display of the transformed image;
- generate a rule defined in the second color space in response to a color characteristic setting adjusted by a user input, the rule including functions representing respective colors of the second color space, the functions computed based on the color characteristic setting adjusted by the user input;
- modify a color characteristic of the transformed image using the rule defined in the second color space, wherein modifying the color characteristic comprises applying the functions to respective color values of the transformed image;
- and
- control display of the modified transformed image.
A non-transitory computer-readable storage medium storing instructions that upon execution cause a controller to:
- transform an image, defined in a first color space, to a second color space;
- receive a user input defining a color characteristic setting;
- generate a rule using the color characteristic setting, the rule including functions representing respective colors of the second color space, the functions computed based on the color characteristic setting defined by the user input;
- and
- modify the transformed image displayed in the second color space using the generated rule, wherein modifying the transformed image comprises applying the functions to respective color values of the transformed image.
