First Claim
Patent Images
1. An image sensor comprising photosensitive pixels including red pixels that are particularly sensitive to red light and monochrome pixels that are sensitive to plural colors of light, wherein:
- said photosensitive pixels are arranged in 2×
2 pixel groups that each respectively consist of four of said photosensitive pixels including exactly one of said red pixels and exactly two or exactly three of said monochrome pixels;
said 2×
2 pixel groups are arranged to form a repeating pattern of rows and columns of said photosensitive pixels covering an area of said image sensor;
each one of said rows that contains at least one of said red pixels consists of only ones of said red pixels alternating successively with ones of said monochrome pixels; and
each one of said columns that contains at least one of said red pixels consists of only ones of said red pixels alternating successively with ones of said monochrome pixels.
