Abstract
Hue is controlled using a saturation control circuit. A first color space value is adjusted based on a hue angle and a saturation value, and a second color space value is adjusted based on the hue angle and the saturation value. The first and second color space values are processed to obtain a hue-adjusted color space value.

A method of controlling hue using a saturation control circuit, comprising:
- adjusting a first color space value based on a product of a saturation value and a cosine of a hue angle to produce a first adjusted color space value;
- adjusting a second color space value based on a product of a saturation value and a sine of the hue angle to produce a second adjusted color space value;
- modifying bit representations of the first adjusted color space value and the second adjusted color space value;
- and
- adding the first adjusted color space value and the second adjusted color space value to obtain a hue-adjusted color space value.
An apparatus comprising a saturation control circuit, the saturation control circuit comprising:
- first circuitry to adjust a first color space value based on a product of a saturation value and a cosine of a hue angle to produce a first adjusted color space value;
- second circuitry to adjust a second color space value based on a product of the saturation value and a sine of the hue angle to produce a second adjusted color space value;
- modification circuitry to modify bit representations of the first adjusted color space value and the second adjusted color space value;
- and
- third circuitry to add the first adjusted color space value and second adjusted color space value to obtain a hue-adjusted color space value.
An article comprising a machine-readable medium which stores executable instructions for controlling hue, the executable instructions causing a machine to:
- adjust a first color space value based on a product of a saturation value and a cosine of a hue angle to produce a first adjusted color space value;
- adjust a second color space value based on a product of the saturation value and the sine of the hue angle to produce a second adjusted color space value;
- modify bit representations of the first adjusted color space value and the second adjusted color space value;
- and
- add the first adjusted color space value and the second adjusted color space value to obtain a hue-adjusted color space value.
