Scientific paper

We demonstrate a non-orthogonal architecture for a CMOS active pixel image sensor, called here pyramidal architecture, for improved two-dimensional spatial sampling. In the pyramidal architecture 2D sampling using concentric rings replaces the 1D row sampling in the classical imager architecture, and diagonal output busses replace the conventional vertical column busses. The noise topology of our suggested pyramidal CMOS image sensor is interesting due to its distribution on the diagonal axis. The Human visual system is less sensitive to contrast that are obliquely oriented, which is known as the oblique effect. Using a new realistic spatial filter model for the perceived fixed pattern noise in the pyramidal architecture is reduced due to the oblique effect.
