Color Depth

|
Digital images are recorded as pixels, which are small square blocks or picture elements that are combined to form the image. Each pixel contains information about the colors recorded. The color depth refers to the number of bits within each pixel and the corresponding number of colors within those bits. When more data can be recorded or captured (higher resolution devices), the bit depth is higher, which results in greater color accuracy. The term applied to the ability of the camera sensor to record the spectrum of colors in the image. Pixels are created as tiny points of light, which have been converted from data compiled by the camera''s image sensor.
