Digital image representation is perceptually uniform if a small perturbation of a component value – such as the digital code value used to represent red, green, blue, or luminance – produces a change in light output at a display that is approximately equally perceptible across the range of that value. Most digital image coding systems – including sRGB (used in desktop graphics), BT.709 (used in high-definition television, HD), Adobe RGB (1998) (used in graphics arts), and DCI P3 RGB (used in… CONTINUE READING
