A color television camera includes a plurality of solid-state imagers each of which is responsive to different spectral components. A thermal servo senses the temperature of an imager and controls its temperature so as to control thermally generated noise. The temperature sensor may be integral with the chip and further may be a component ordinarily used for other purposes. The other imagers may be uncooled or may be cooled in an open-loop fashion under the control of the thermal servo. |
