Real-time digital processor for producing full resolution color signals from a multi-color image sensor

摘要: A digital processing system is described for luminance and chrominance signals from a single, multi-color image sensor. By concentrating signal improvements corrections into an application-dependent post-processing phase, the pre-processing functions are isolated in signle, generic pre-processor integrated circuit that provides fully interpolated color real-time by utilizing pipelined architecture. The separates interpolation so as to operate partly quantized linear space logarithmic space. processed black reference clamp, defect concealment separation space, using right shifts additions approximate predetermined multiplications. then transformed hue log white balance chroma (hue) interpolation. With green separately adjusted gain, red, blue output circuit.
