Trichromatic RGB Cameras

Trichromatic RGB cameras are a type of digital imaging sensor that capture color information by using three separate light-sensitive elements, each responsive to a different primary color – red, green, and blue (RGB). This approach to color imaging is based on the trichromatic color theory, which states that all colors can be reproduced by combining these three primary colors in varying proportions.

How Trichromatic RGB Cameras Work

In a trichromatic RGB camera, the image sensor is divided into a grid of light-sensitive pixels. In front of each pixel, there is a tiny color filter that only allows one of the three primary colors (red, green, or blue) to reach the underlying light-sensing element.

The three color-filtered pixels work together to capture the full-color information for that specific area of the image:

  1. Red Pixel: Captures the intensity of the red component of the light.
  2. Green Pixel: Captures the intensity of the green component of the light.
  3. Blue Pixel: Captures the intensity of the blue component of the light.

By combining the information from these three color-filtered pixels, the camera can determine the overall color of that particular area of the image.
