Pseudo-Random Pixel Placement Sensor

Kanazawa University, Japan published a paper on pseudo-random pixel placed sensor presented at 2009 International Symposium on Intelligent Signal Processing and Communication Systems (ISPACS 2009) December 7-9, 2009:

A CMOS Image Sensor with Pseudorandom Pixel Placement for Clear Imaging
Yui Maeda and Junichi Akita

The random pixel placement is supposed to solve artifacts problem of regular lattice-placement of pixels:

Unfortunately, paper does not discuss the most interesting part - how to make this pseudo-random placement in color. And how to interpolate the color picture out of irregular Bayer pattern where color crosstalk changes from one pixel to another.

  1. some works have been published before by using randomly arranged micro-facette layer on the sensor .... in this case, no special signal processing is needed ...
