发明名称 Digital camera that automatically adjusts LCD brightness according to ambient light
摘要 A digital camera includes a LCD that has a back light whose intensity level is set at a point midway between a maximum intensity setting and a minimum intensity setting. The back light level is then adjusted automatically from this default setting to a brightness level that corresponds to a measured scene level. The back light intensity level and contrast level of the LCD then change automatically thereafter to correspond to the measured scene level whereby the LCD controls are adjusted according to the lighting environment.
