Abstract
An automatic brightness adjustment for devices with displays includes the capability to assess ambient light. The assessment may be made using circuitry, such as a light meter circuit, by exploiting exposure control circuitry, or using other approaches. The ambient light value is sent to a brightness adjustment driver, which may employ a look-up table to keep track of brightness adjustments for particular ambient conditions. The look-up table may include distinct adjustment values based upon the type of display.
