Abstract
Dark current noise may be compensated for in a digital imaging sensor by measuring the temperature of a silicon diode embedded on the same integrated circuit with the image sensor. This information may be used together with initial dark current calibration information, to provide dark current compensation on the fly during image capture. In some embodiments this may avoid the need for multiple shutter operations or repeatedly capturing a dark frame and then capturing a regular image frame.
