A Bayer filter mosaic is a color filter array (CFA) for arranging RGB color filters on a square grid of photosensors. Its particular arrangement of color filters is used in most single-chip digital image sensors used in digital cameras, camcorders, and scanners to create a color image. The filter pattern is 50% green, 25% red and 25% blue, hence is also called RGBG,GRGB, or RGGB.

Bryce Bayer's patent (U.S. Patent No. 3,971,065) in 1976 called the green photosensors luminance-sensitive elements and the red and blue ones chrominance-sensitive elements. He used twice as many green elements as red or blue to mimic the physiology of the human eye. The luminance perception of the human retina uses M and L cone cells combined, during daylight vision, which are most sensitive to green light. These elements are referred to as sensor elements, sensels, pixel sensors, or simply pixels; sample values sensed by them, after interpolation, become image pixels. At the time Bayer registered his patent, he also proposed to use a cyan-magenta-yellow combination, that is another set of opposite colors. This arrangement was unpractical at the time because the necessary dyes did not exist, but is used in some new digital cameras. The big advantage of the new CMY dyes is that they have an improved light absorption characteristic; that is, their quantum efficiency is higher.
And, while we've seen alternatives and variations of the Bayer color filter pattern, the SD9 represented one of the most concerted attempts to offer a totally different way of capturing color in digital photography.

The filters are arranged in a specific pattern (typically a four-pixel repeating square known as the Bayer pattern), which allows the camera’s computing hardware to combine the captured data into a full-colored image.

Fitted with the 1/1.67” S5KHM6 sensor that has 3X In-sensor Zoom, the Samsung S5KHM6 is a 1/1.67" format, 108 MP class stacked imager featuring 0.64 µm pixel pitch, ISOCELL 2.0 pixels, and Nonacell BayerRGB color filters.
What is a Bayer filter and what does it mean?. Underpinning most of our cameras through the history of digital photography has been the Bayer ColorFilterArray... How Bayer's baby changed the world.
There are still a few digital cameras on the market today that have monochrome sensors ... The key difference is that color sensors have one of three, red, green, or blue, filters above it, called a Bayer pattern array. The real question is ... .
QuadBayer, high res, 2x 'zoom' and DualExposure... In each instance they are Dual Bayer designs, which use an oversized version of the Bayer color filter pattern, stretched out over four pixels.
Multi-shot modes that try to cancel-out the effect of the Bayer filter or oversample the scene to produce more detailed images have become increasingly common as engineers look for ways to exploit the presence of in-body stabilization mechanisms.
As usual, when we see '48MP' on smartphone camera, it's a strong hint that the sensor has a quad bayer color filter array , which is designed so that groups of four pixels can be combined to give 12MP images.
Similarly, non-silicon approaches such as QuadBayer/Tetracell color filter layouts are being adopted, giving the options of combining pixels in low light, using different exposures or gain levels on ...

It's defiantly different in a way as if to say, 'Hey, I'm not like the other cameras.' Inside, the camera uses Foveon sensors, which capture light differently than Bayer and other color-filter sensors ...
With a color filter array that ... This, in turn, allows better resistance to color moiré versus the more traditional Bayer filter, which skips either the red or blue pixels in every other line or column.
