.... of depleted regions, which conditions the proportion of photogenerated charges collected, may become too shallow, thus requiring less obvious charge collection techniques [2] Taking advantage of the new deal for image capture purposes, specific CMOS readout circuit techniques have been developed [3,4] that associate a photodiode with a few MOS transistors in each pixel for faithful off array signal transmission. With submicronic transistors, they imply a minor degradation of pixel size or fill factor. The resulting CMOS imagers have recently matched the standards of mainstream CCD imagers [2] ....

....SMART PIXEL CHIPS In this paper, pixel denotes the elementary sensory unit used to detect pointwise light signals. These sensory units are realized in CMOS technology using any compatible junction device to generate a current whose value is an increasing function of the light intensity [3] 13] [14]. The acquisition of two dimensional scenes requires pixels arranged onto regular grids, as shown in Fig. 1. Each pixel in this sensory plane generates a current I c which codifies a corresponding point of the input image, where the index c (i, j) indicates the pixel at the i th row and j th ....
