Abstract:
1. A mobile apparatus comprising: a display; an imager to capture an image, provide an exposure for the image and adjust a brightness of the display, wherein said imager comprises a light sensor to detect an amount of light in a surrounding area, wherein the light sensor accumulates light energy over an integration interval to provide an indication of the amount of light; and a processor to determine a perceived brightness value based on an equation whose value varies with the detected amount of light, wherein the equation comprises a factor that is a direct adaptation effect and a factor that is a lateral adaptation effect, and wherein conflicts between direct and lateral adaptations of a user's eye are to be avoided based on the perceived brightness value, wherein the lateral adaptation effect comprises a sum of weighted adaptations to spot luminances in proportion to their angular displacements from an axis of vision.
