Method and apparatus for enhanced automatic adjustment of focus, exposure and white balance in digital photography

摘要

A method, apparatus and computer program are described where signals are received from a camera unit (310) having an image sensor with a plurality of image detectors. The signals include first signals received from first pixel detectors corresponding to a first image area and second signals received from second pixel detectors corresponding to a second image area surrounding the first image area. Camera settings of a setting group are automatically controlled (340) based on the first signals. The settings group has at least one of focus control, exposure control and white balance control. Changes in the setting group are predicted based on the second signals. A change is detected in the first image area and used to adapt the automatic control (340) of the camera settings of the settings group. Control signals are output to the camera unit (310) to control (340) the camera settings of the settings group.
