Abstract:
1. An imaging sensor structure comprising: a plurality of pixels arranged in at least one row, wherein said plurality of pixels is an array of pixels; and a first type pixel located adjacent to a second type pixel in said at least one row, wherein said first type pixel includes a color filter, said second type pixel is a color filter-free light efficient cell (LEC) collecting three times the per unit area energy of the first type pixel, LECs having at least twice the light sensing area of the first type pixels, each LEC not sharing a common boundary with any other LEC and sensing all light to the respective light sensing area independently of light sensed by each other LEC, wherein said surface area of said second type pixel is L-shaped occupying two rows in one column and two columns in one row and being greater than said surface area of said first type pixel, and wherein said imaging sensor is a CMOS imaging sensor comprises diagonals of green pixels interleaved with diagonals of alternating blue pixels and red pixels, said diagonals being periodically interrupted by said plurality of L-shaped LECs.
