A real-time 1024/spl times/1024 image processor for digital motion camera systems is described. The application-specific IC (ASIC) corrects dark current and white imbalance pixelwise, and performs a color interpolation over nine lines of images from a miniaturized camera head housing a single charge-coupled device (CCD). A color space transformation is implemented to achieve true-color motion images with frame rates up to 30 frames/s. Additional features include a focus and illumination criteria calculation and a megapixel-to-PAL scan conversion. The chip area is 49 mm/sup 2/, and it was fabricated in a single-poly three-layer-metal 0.35-/spl mu/m CMOS process. The device is packaged in a 208-pin ceramic quad flat package (CQFP), and dissipates 278 mW at 2.5 V.
