Color depth (sometimes also called bit depth) refers to the number of bits used to represent each pixel in a digital image. The common values for color depth and the number of possible colors each pixel can represent are given in the following table:bits possible colors
12 416 8256 15 32,768
16 65,536
24 16,777,216
The more bits are used by each pixel, the more closely a digital image can approximate a photograph (and the morememory the image occupies).
