Frame grabbers are image processing computer boards that capture and store image data for industrial applications such as quality control. Frame grabbers can operate in monochrome or color.  Monochrome is black and white, or grayscale; the image is presented in black, white, and grayscale.  The range of colors is generated with varying combinations of different discrete colors.  One common technique is sensing the red, green, and blue components (RGB) and combining them to create a wide spectrum of colors.
