Image sensor having nonlinear response

Martin Vetterli, Edoardo Charbon, Sabine Süsstrunk, Luciano Sbaiz

In previously known imaging devices as in still and motion cameras, for example, image sensor signal response typically is linear as a function of intensity of incident light. Desirably, however, akin to the response of the human eye, response is sought to ...
