Pulsed light keying method

A method has been developed to generate a key signal for an object or person in the image from a standard TV camera without using a chroma-key background. The method can be used as a form of "depth keying", for example to allow graphics to be keyed into a TV image so as to appear behind a presenter but in front of the background behind him.

The method involves illuminating the object or person with pulsating coloured light, which the camera sees as being "on" and "off" in successive images. Real-time image processing algorithms detect the areas of the image with this characteristic illumination, generate a key signal for these areas, and also provide a ?clean? version of the original image with the pulsating light removed.
