Claim:
1. An imaging device comprising a pixel array on a substrate in which a plurality of pixels are arranged in an array, the pixels configured to convert light into electric signals, said pixels comprising a plurality of color filter pixels and at least one clear pixel, wherein: the plurality of color filter pixels include at least two of (i) a first color filter pixel with a first filter effective to cause the first color filter pixel to have a peak spectral sensitivity for red light, (ii) a second color filter pixel with a second filter effective to cause the second color filter pixel to have a peak spectral sensitivity for blue light, and (iii) a third color filter pixel with a third filter effective to cause the third color filter pixel to have a peak spectral sensitivity for green light; the at least one clear pixel has no filter or a fourth filter with a high transmittance such that the clear pixel is sensitive to white light; at least a portion of the plurality of color filter pixels is arranged in an array; the at least one clear pixel is arranged in the array at a given position of a given row and a given column with respect to the at least two of the first color filter pixel, the second color filter pixel, and the third color filter pixel; and a first read channel is exclusively coupled to the at least one clear pixel and a second read channel is exclusively coupled to the plurality of color filter pixels.
