Abstract

An electronic motion picture camera for recording a sequence of images includes a sensor device having a two-dimensional arrangement of sensor elements that generate electrical signals in dependence on an exposure to light. A first group of the sensor elements forms a recording region of the sensor device and generates recording signals, and a second group of the sensor elements forms a monitoring region of the sensor device and generates monitoring signals, wherein the monitoring region surrounds the recording region. A memory device stores the recording signals, but not the monitoring signals. A display device displays the recording signals, the monitoring signals and a frame signal representing a border between the recording region and the monitoring region of the sensor device, and the border between the recording region and the monitoring region is kept fixed during the recording of the sequence of images.
