What term describes the smallest unit of information within a digital image?

• A. Picture element (pixel)
• B. Detector element (DEL)
• C. Display element
• D. Bit

Answer: (A)

Digital images are built from tiny picture elements called pixels, which are the smallest spatial units of the image. Each pixel represents the color (and brightness) at one specific spot on the image’s grid, so it’s the smallest unit you can address to form the picture. While the color data inside a pixel is stored using bits (multiple bits per color channel), the unit that defines the image’s structure and detail is the pixel itself. The other terms aren’t standard builders of an image: a bit is the basic information unit in general, but it’s not the spatial unit that makes up the image, and the other phrases aren’t used to describe the image’s fundamental element.
