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.

The signal samples of the kth microphone signal are encoded, upon acquisition by the analog-to-digital converter, with a certain bit depth dictated by the hardware in use.
The number of k bits per pixel is the bit depth. Because the binary number system uses base 2, k bits is equal to 2 to the power of k (k bits = [2.sup.k]).
The three most important terms here are resolution (described as pixels per inch, or ppi, for monitors and scanners and dots per inch, or dpi, for printers), number of colors (bit depth) and image size (actual dimensions of the image area when printed).
A measure of how many binary units, zeros and ones, can be used to describe the image is bit depth. A simple calculation based on the well depth yields the usable bit depth of the sensor.
The sender then queries the receiver's capabilities, including resolution, color capability, and bit depth.
The digital image data acquisition and processing should be carried out according to the latest technology with a detector with high bit depth and at least 30 cm x 40 cm and displayed on a high-resolution, Ceiling-mounted large monitor.

The colour space of our lenses is also wide enough to establish the expansion of colour volume and realise the smooth tonality of colour, as long as the camera is equipped with HDR functionality and bit depth capability.
High Dynamic Range -- HDR10 and backwards compatible HDR implementations illustrate improved color space, deeper luminance and increased bit depth for enhanced image quality.
