Detailed explanation-1: -A binary image is one that consists of pixels that can have one of exactly two colors, usually black and white. Binary images are also called bi-level or two-level, Pixelart made of two colours is often referred to as 1-Bit or 1bit. This means that each pixel is stored as a single bit-i.e., a 0 or 1.
Detailed explanation-2: -Thus, a pure black and white image (i.e. no greys) would be described as a 1-bit or 2-colour image, since every pixel is either black (0) or white (1). Common colour depths include 8-bit (256 colours) and 24-bit (16 million colours).
Detailed explanation-3: -A 1-bit image contains just two tones, 0 Black and 255 White, so the intensity of each pixel can be specified by one binary digit, that is one bit. Examples are shown of typical 1-bit images created by program, graphic user interface, scanner, and camera.
Detailed explanation-4: -Binary images are images whose pixels have only two possible intensity values. Numerically, the two values are often 0 for black, and either 1 or 255 for white.
Detailed explanation-5: -Each pixel typically consists of 8 bits (1 byte) for a Black and White (B&W) image or 24 bits (3 bytes) for a color imageāone byte each for Red, Green, and Blue.
