Semiconductor image sensor with integrated pixel heating and method of operating a semiconductor image sensor

摘要

The semiconductor image sensor comprises a plurality of pixels (1) with photo sensors (2). At least one heater (4) is integrated with the photo sensors and is arranged in at least one of the pixels or in the vicinity of at least one of the pixels. An appropriate operation of the heater will increase the temperature of the relevant pixel. Thus it is possible to achieve a local compensation of a temperature difference that may be due to the operation of an integrated readout circuit (3) or any other integrated component generating heat.
