An image sensor system digram

The performance of current systems is restricted by several factors. First of all, high-quality detector depends on complex materials and processes, which are very difficult and/or costly to be integrated in a convention semiconductor process. Secondly, the inherent paralleling processing potential is poorly utilized. For example, although the photon detector cells are organized as a 2-D array, each column of
