Patent Images

1. An array of image sensing pixels, wherein the array of image sensing pixels includes a plurality of vertical columns and wherein each of the vertical columns spans substantially entirely across the array in an approximately vertical direction, the array comprising:

  • a repeating block of eight pixels, wherein the repeating block of eight pixels comprises;

    four pixels of a first color arranged in two pairs of horizontally adjacent pixels;

    two pixels of a second color arranged in a pair of vertically adjacent pixels; and

    two pixels of a third color arranged in a pair of vertically adjacent pixels, wherein a first plurality of the vertical columns comprises vertical columns formed entirely from pixels of the first color, wherein each of the pixels in the repeating block of eight pixels includes a photosensitive element and a transfer transistor coupled to the photosensitive element, and wherein the repeating block of eight pixels includes two charge summing lines each of which is connected to four of the transfer transistors of the pixels in the repeating block of eight pixels.
