Abstract

The present invention relates to an image sensor and to an imaging system comprising such a sensor. According to the invention, the overall conversion curve describing the conversion between photon flux and digital number comprises a first region in which the conversion is essentially linear and a second region in which the conversion is essentially non-linear. According to the invention, the non-linearity of the second region is obtained by operating the photodiode of the image sensor in its non-linear range and by changing the gain associated with the conversion between pixel voltage and digital number.
