Abstract
A pixel array in an image sensor, the image sensor and a digital camera including the image sensor. The image sensor includes a pixel array with colored pixels and unfiltered (color filter-free) pixels. Each unfiltered pixel occupies one or more array locations. The colored pixels may be arranged in uninterrupted rows and columns with unfiltered pixels disposed between the uninterrupted rows and columns. The image sensor may in CMOS with the unfiltered pixels reducing low-light noise and improving low-light sensitivity.
