bit depth

[′bit ‚depth] (computer science) In a digital file, the number of colors for an image; calculated as 2 to the power of the bit depth; for example, a bit depth of 8 supports up to 256 colors, and a bit depth of 24 supports up to 16 million colors.

bit depth

The maximum numeric value in a coding system. The bit depth is the maximum number of bits in the system's storage element and represents either the total number of discrete items that can be represented or the largest magnitude. For example, the bit depth of an audio sample determines its dynamic range (see audio bit depth). The bit depth of a screen pixel determines the total number of colors that can be displayed (see color depth). See bit specifications and binary values.

bit depth

A description of the number of colours or shades of gray a monitor can display or a scanner can process; the higher the bit depth, the higher the number of colour hues that can be supported

bit depth

The number of shades of gray in a digital image. Bit depth is defined as 2ⁿ, where the multiplier 2 indicates that the image is in black and white and n represents the power to which the computer can multiply this function. Therefore a bit depth of 2¹ would produce 2 shades of gray; a bit depth of 2¹² would produce 4096 shades of gray. Digital radiography, CT, and MR images are produced with bit depths of 10 or 12.
