Definition of bit depth

bit depth

1.  The number of bits used to process scanned images. The greater the number of bits, the more colours or levels of gray that can be used to display the image.

More Information:
Color depth or bit depth, is a computer graphics term describing the number of bits used to represent the color of a single pixel in a bitmapped image or video frame buffer. This concept is also known as bits per pixel (bpp), particularly when specified along with the number of bits used. Higher color depth gives a broader range of distinct colors.
