Abstract

An edge detection method includes reading at least a portion of wide-band pixel signals generated by wide-band pixels of an image sensor. The image sensor also includes narrow-band pixels that generate narrow-band pixel signals that remain unread. The method also includes sending the wide-band pixel signals to an image signal processor, forming a partially-filled reference image based on data from the wide-band pixel signals; and applying an edge-forming technique to the partially-filled reference image to produce an edge map. An edge detection system includes a two-dimensional array of pixels having wide-band pixels and narrow-band pixels, an image signal processor for producing an edge map from a partially-filled reference image, and a readout circuit for generating the partially-filled reference image for the image signal processor. The partially-filled reference is based only on at least part of the wide-band pixels.
