Abstract

We present a new digital signal processor developed for digital camcorder applications. Taking the digital image signal from A/D converter, the signal processor generates luminance and chrominance signals of the image using an efficient RGB interpolation algorithm and histogram accumulation. We propose a low-cost RGB interpolation algorithm that has little image degradation and show the usefulness of histogram accumulation implemented in the signal processor
