Abstract :
Intended for industrial applications, a pixelstructure with a logarithmic response is presented in this paper. An XY-addressable image architecture based on this pixel was implemented in silicon. Measurement data on this sensor are discussed. The logarithmic response will be quantified using a more general signal to noise ratio. A parallel is drawn with concepts of human perception theory.
