Training Tips - RGB Imaging | Machine Vision Lighting

Color cameras use grids of four pixels to achieve color imaging. Each pixel is covered with a colored film to capture color information. The array consists of one red pixel, one blue pixel, and two green pixels. In order for the camera to calculate color information, each pixel borrows information from the neighboring pixel. When combined, this grid of four pixels can accurately show color output. What this means, though, is that compared with a monochrome camera of similar resolution, a color camera isn't able to achieve as high of image clarity. Instead, users can use an RGB light source and a monochrome camera and cycle through red, green, and blue light, taking an image at each cycle. This saves the color information, and when combined, create a color image with clarity down to the pixel level. Watch as our director of training, Steve Kinney, demonstrates this principle using an RMX140-RGB and a monochrome camera. ---------------------------------------------------------------------------------------------------------------------------------- Smart Vision Lights is the leading designer and manufacturer of LED lighting solutions for any type of machine vision or automation camera application.
