Bit depth, sometimes referred to by the name color depth, may refer to two distinct instances. It can either provide information on the number of bits needed to create the color of a single pixel, as well as its component color. This information is utilized in bitmapped video and image files as well.
The Bit Depth value determines the number of tones an image video can display. The greater the value is, the more tones will be represented, and the reverse is true.
When discussing a 24-bit image, typically, the bits are divided into three fundamental shades that comprise the RGB spectrum. That means that they have eight bits of red and eight bits for green, and 8 bits to represent blue. The colors, when combined, can represent various different hues.
