Method for adjusting the operating parameters of a digital camera alters the pixel values of the image sensor during an image recording. A control cycle is used in which the adjustment value is set from the pixel values of a recorded image. The operating parameters adjusted are the shutter time, aperture size, signal amplification and offset of the detector elements. An Independent claim is made for a digital camera where the lighting or flash is controlled by the pixel values of the image sensor.
