'''Contrast''' is the [[difference]] in [[visual]] properties that makes an object (or its [[representation]] in an image) distinguishable from other objects and the background. In visual [[perception]] of the real world, contrast is determined by the [[difference]] in the [[color]] and brightness of the object and other objects within the same field of view. Because the [[human]] visual system is more sensitive to contrast than [[absolute]] [[luminance]], we can perceive the world similarly regardless of the huge changes in [[illumination]] over the day or from place to place. | '''Contrast''' is the [[difference]] in [[visual]] properties that makes an object (or its [[representation]] in an image) distinguishable from other objects and the background.
