bit depth

Also found in: Dictionary, Thesaurus, Legal, Encyclopedia, Wikipedia.

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.

Digital image compression

This technique can also be used with color negatives, but it must be done at a high bit depth or the data will be severely compromised because many bits of data will be wasted when the film base's orange cast is removed.
