WebJul 23, 2016 · Each photo sensor is sensitive for one of the primary colors: red, green and blue. The way those photo sensors are organized is called the Bayer filter, after its inventor, Bryce Bayer of Eastman Kodak. After an image is taken, four photo sensors compose the RGB value of one pixel in the resulting image. WebThe Bayer CFA is a pattern of color filters [4] typically arranged as shown in Fig. 4.17. Half of the filter elements are green and the remainder are divided between blue and red. This approximates human photopic vision, where the M and L cones combine to produce a bias in the green spectral region. Sign in to download full-size image Figure 4.17.

WebMar 29, 2024 · Looking at just the green component, you should see that a Bayer sensor can still capture the same horizontal and vertical green (and luminance) information as a sensor sampling every pixel. You lose something on the diagonals, but you still get a good level of detail capture. This is a key aspect of what makes Bayer so effective. * WebFeb 15, 2024 · Bayer cameras rely on a predefined pattern of color filters which overlay the pixels on a camera’s imager.
