28-M CCD imager with RGB compatible binning feature for professional applications

A 28-M pixel, full-frame CCD imager with 7.2×7.2 μm2 pixel size and Bayer RGB color pattern was developed for use in professional applications. As unique option a RGB compatible binning feature was designed into this sensor. This gives the possibility to exchange resolution for sensitivity, read-out speed and signal-to-noise ratio. This paper presents the device architecture, RGB binning principle and evaluation results of the overall sensor performance. The performed device simulations and the evaluation results of the RGB binning feature are described in detail.
