  A concept for a novel CMOS image sensor suited for analog image
pre-processing is presented in this paper. As an example, an image restoration
algorithm for reducing image noise is applied as image pre-processing in the
analog domain. To supply low-latency data input for analog image preprocessing,
the proposed concept for a CMOS image sensor offers a new sensor signal
acquisition method in 2D. In comparison to image pre-processing in the digital
domain, the proposed analog image pre-processing promises an improved image
quality. Furthermore, the image noise at the stage of analog sensor signal
acquisition can be used to select the most effective restoration algorithm
applied to the analog circuit due to image processing prior to the A/D
converter.
