Abstract
A method for creating a luminance effect, including: obtaining a source image in a red-green-blue (RGB) color space; obtaining a luminance effect parameter; generating an international color consortium (ICC) device link profile based on the luminance effect parameter; and converting the source image in RGB color space to a final image in RGB color space using a color conversion function with the ICC device link profile.
Claims20
A method for creating a luminance effect, comprising:
- obtaining, by a processor, a source image in a red-green-blue (RGB) color space;
- obtaining, by the processor, a luminance effect parameter;
- generating, by the processor, an international color consortium (ICC) device link profile based on the luminance effect parameter;
- and
- converting, by the processor, the source image in RGB color space to a final image in RGB color space using a color conversion function with the ICC device link profile.
A non-transitory computer readable medium (CRM) storing instructions for creating a luminance effect, the instructions comprising functionality for:
- obtaining a source image in a red-green-blue (RGB) color space;
- obtaining a luminance effect parameter;
- generating an international color consortium (ICC) device link profile based on the luminance effect parameter;
- and
- converting the source image in RGB color space to a final image in RGB color space using a color conversion function with the ICC device link profile.
A system for creating a luminance effect from a luminance effect parameter, comprising:
- a processor;
- a buffer for storing a portion of a source image in a RGB color space;
- a color profile module executing on the processor and configured to generate an international color consortium (ICC) device link profile based on the luminance effect parameter;
- and
- a conversion engine executing on the processor and comprising a color converter configured to convert the portion in the buffer to a final image in RGB color space using a color effects transform generated from the ICC device link profile.
