AN IMAGE PICKUP DEVICE HAS AN IMAGE SENSOR (6) GENERATING AN IMAGE SIGNAL (IMG), A PULSE PATTERN GENERATOR (12) GENERATING A DRIVING SIGNAL (DRV) FOR THE IMAGE SENSOR (6) AND AN AMPLIFIER (8) FOR AMPLIFYING THE IMAGE SIGNAL (IMG) WITH A GIVEN GAIN (GAIN). ADJUSTING MEANS (14, 16) ARE PROVIDED TO SET THE GAIN (GAIN).@THE POWER OF THE DRIVING SIGNAL (DRV) IS CONTROLLED DEPENDING ON THE GAIN (GAIN). FOR INSTANCE, THE PULSE HEIGHT (PH) OF THE DRIVING SIGNAL (DRV) IS SET DEPENDING ON THE GAIN (GAIN).
