ABSTRACT:
Color is edited using a color representation including digital values B (brightness), e and ƒ such that B=√{square root over (D2+E2+F2)}, e=E/B, ƒ=F/B, where DEF is a linear color coordinate system. Alternatively, color is represented using digital values B, C (chroma) and H (hue), where cos C=D/B and tan H=E/F. Brightness can be changed without a color shift by changing the B coordinate and leaving unchanged the other coordinates e and ƒ or C and H. Other image editing techniques and other features are also provided.
