Paper Abstract

Typical one-chip color cameras use analog video processing circuits. An improved digital camera architecture has been developed using a dual-slope A/D conversion technique, and two full custom CMOS digital video processing ICs, the 'CFA processor' and the 'RGB post- processor.' The system uses a 768 X 484 active element interline transfer CCD with a new 'field-staggered 3G' color filter pattern and a 'lenslet' overlay, which doubles the sensitivity of the camera. The digital camera design offers improved image quality, reliability, and manufacturability, while meeting aggressive size, power, and cost constraints. The CFA processor digital VLSI chip includes color filter interpolation processing, an optical black clamp, defect correction, white balance, and gain control. The RGB post-processor digital IC includes a color correction matrix, gamma correction, two-dimensional edge-enhancement, and circuits to control the black balance, lens aperture, and focus.
