Paper Abstract
An approach for darksignal-correction is presented that uses a model of each pixel's darksignal, which depends
on the sensor's settings (integration time and gain) and its temperature. It is shown how one can improve the
outcome of such a darksignal-correction strategy by using the darksignal of some pixels in order to compute
an estimate of the sensor's temperature. Experimental results indicate that the darksignals' dependency on
temperature and gain is more complex than considered in up-to-date darksignal models. In this paper it is
shown how one can cope with this complex behaviour when estimating the temperature out of the darksignal.
Experimental results indicate, that our method yields better results than using temperature measurements of
dedicated temperature sensors.
