Following the groundbreaking work of Bell Laboratories to invent the CCD sensors crucial to the formation of digital photography, Bruce Bayer patented the second now standard mechanism in 1976, the Bayer Color Filter Array. Designed to mimic the physiology of the human eye, this filter has a pattern to electronically separate colors to be captured, read, and manipulated by a computer. The pattern alternates between red and green light sensitive strips and blue and green strips. The 2:1 ratio of green sensors to red and blue respectively is meant to aid the human eye in correctly seeing colors with the extra data captured by the green sensors.
