Original Color Space RGB
Form the opened image the RGB values are read. The distributions of the values is visualized in the 3D RGB space.
By choosing a different color space the color values are converted to the new space which then is visualized.
For the device-independent color spaces sRGB an illumination D50 is assumed.
Here the conversion is show as Java source code.
Luminance / Chrominance Color Spaces
The YUV -model is used for the Pal-tv system.
|The modes HSB (Hue, Saturation, Brightness), HSV (Hue, Saturation, Value) and
HSL (Hue, Saturation, Lightness (also Luminance or Luminosity )) are used for the color selection of painting tools.
HMMD (Hue, Max, Min, Diff) is used by the MPEG7 standard.
|Tristimulus Color from the (CIE): "Commission Internationale de l'Eclairage"|
|Newer color spaces of the CIE, Lab = device-independent color space (internal color space of Photoshop)|
