In photography and computing, a grayscale or greyscale Digital Image was an image in which the value of E Ach pixel is a single sample, which is, it carries only intensity information. Images of this sort, also known as black-and-white, is composed exclusively of shades of gray, varying from black at the Weakest intensity to white at the strongest. ^[1]

Grayscale images is distinct from one-bit bi-tonal black-and-white images, which in the context of computer imaging is I Mages with only the colors, black and white (also called bilevel or binary images). Grayscale images has many shades of gray in between.

Gray image and black and white image, in the field of computer graphics black and white images only two colors, grayscale images between black and white there are many levels of color depth.

A binary image is a digital image which has only the possible values for each pixel. Typically, the colors used for a binary image is black and white, though any of the colors can be used. The color used for the object (s) in the image is the foreground color while the rest of the image is the background color. ^{[1] in the document-scanning industry, which is often referred to as "bi-tonal".}

Binary images is also called bi-level or two-level. This means the pixel is stored as a and a single bit-i.e., a 0 or 1.

A binary image can be stored in memory as a bitmap, a packed array of bits. A 640x480 image requires 37.5 KiB of storage. Because of the small size of the image files, fax machine and document management solutions usually use this format. Most of the binary images also compress well and simple run-length compression schemes.

Binary images can be interpreted as subsets of the two-dimensional integer lattice Z2; The field of morphological image processing is largely inspired by this view.

A two-value image is a digital image with only two possible values per pixel. People often use black -and-white,b&w, monochrome images to represent binary images, but they can also be used to represent any image that has only one sampled value per pixel, such as grayscale images.

Binary images often appear in digital image processing as image masks or in the results of image segmentation, binary and dithering. Some input, such as laser printers, fax machines, monochrome computer monitors, can handle two-value images.

Binary images are often stored using bitmap format.

Binary images can be interpreted as two-dimensional integer lattice Z2, the field of image distortion processing is largely inspired by this point of view.
