PIXEL ARRAY, IMAGING SENSOR INCLUDING THE PIXEL ARRAY AND DIGITAL CAMERA INCLUDING THE IMAGING SENSOR

摘要

PROBLEM TO BE SOLVED: To provide a pixel array in an image sensor, the image sensor and a digital camera including the image sensor. SOLUTION: The image sensor includes a pixel array with colored pixels and unfiltered (color filter-free) pixels. Each unfiltered pixel occupies one or a plurality of 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 be of a CMOS type with the unfiltered pixels reducing low-light noise and improving low-light sensitivity. COPYRIGHT: (C)2007,JPO&INPIT
