Bayer Filter

A Bayer filter is a color filter used in digital cameras and image sensors to capture color images. It consists of a grid of tiny colored filters, arranged in a specific pattern—typically alternating between red, green, and blue. Each pixel on the sensor reads only one color due to this filter, and the camera's software combines the data from multiple pixels to create a full-color image. The Bayer filter is essential for ensuring that the digital image accurately represents the colors of the scene being photographed.
