Abstract
An artistic color gamut display is generated by obtaining maximum and minimum values for an RGB signal. The maximum and minimum values are used as X and Y values for an XY plot. A triangular graticule, or Spearhead display, is generated for the XY plot having a first side representing Lightness, a second side representing saturation and a third side representing Value. The area within the Spearhead display represents valid color gamut. The Spearhead display may be combined with more traditional displays, such as Vector or Arrowhead displays, to provide a completely three-dimensional analysis of the RGB signal in terms of the artistic parameters of Hue, Saturation and Value or Lightness.
Claims13
An artistic color gamut display comprising a triangular space derived from the XY plot of an RGB gamut space, a first side of the triangular space being a monochrome axis, a second side being a Saturation axis, and a third side being a Value axis.
A method of producing an artistic color gamut display comprising the steps of:
- obtaining maximum and minimum values for an RGB signal;
- generating from the maximum and minimum values X and Y values for an XY plot;
- and
- generating a triangular graticule for the XY plot having a first side representing Lightness, a second side representing Saturation and a third side representing Value, the area within the triangular graticule representing valid color gamut.
An apparatus for producing an artistic color gamut display comprising:
- means for obtaining maximum and minimum values for an RGB signal;
- means for generating from the maximum and minimum values X and Y values for an XY plot;
- and
- means for generating a triangular graticule for the XY plot having a first side representing Lightness, a second side representing Saturation and a third side representing Value, the area within the triangular graticule representing valid color gamut.
