Abstract
An adaptive peak value detector, wherein the peak value for a peak hold section is detected, the peak hold section being selected by a peak hold control circuit. A solid-state imaging sensor generates pixel signals representative of an image and the peak value of portions of the pixel signals is detected. The exposure time of the sensor is adjusted as a function of the detected peak value and auto-focusing of the image for the camera is carried out on the basis of the image received during the adjusted exposure time.
