The core is a pixel array of 1281 x 480 rectangular active pixels with a high physical fill factor of 43% (without micro-lenses).
A vertical stripe RGB pastel color filter is used with individual column-correlated double-sampling (CDS) correction circuitry to produce an exceptionally low level of fixed-pattern image noise (FPN).
Individual color gain and offset controls followed by a triple 10-bit analog-to-digital converter further ensure an even color response in the digitized images.
All timing and voltages are generated internally from a single 3.
3V voltage rail and master clock, but the option is available to take control of every aspect of scan timing externally in an FPGA if the user requires the modes of operation extended for advanced imaging.
Pre-programmed modes are available for full-resolution still- and motion-imaging with exposures of 1 µs to 1 second, as well as for a sub-sampled CIF-sized image suitable for the quali...
