1. Apparatus comprising:

  • a plurality of sensors to detect radiation and to output image signals based on the detected radiation; and

    processing circuitry to process the image signals and to output digital image data based on the image signals, wherein the plurality of sensors and the processing circuitry are monolithically formed on a semiconductor substrate within a single integrated circuit chip, and wherein the apparatus further includes;

    at least one temperature sensing element to sense a temperature of the integrated circuit chip; and

    a thermoelectric stabilizer to stabilize the temperature at a predetermined value, wherein the at least one temperature sensing element is monolithically integrated on the semiconductor substrate with the plurality of sensors and the processing circuitry, wherein the at least one temperature sensing element includes at least one sensor of the plurality of sensors, and wherein the predetermined value is an average temperature of at least some of the plurality of sensors.
