Abstract

Methods of creating frames captured with a video camera that are independent of light conditions are presented. In a first method the invention attains this goal by the addition of a modulated light source, for example amplitude modulation (AM), to the background light that illuminates the scene being captured and executing an algorithm that generates processed images in which the effects of the background illumination have been eliminated. In a second aspect the invention is a method of modifying the flash no flash technique by executing an algorithm that averages out the maximum and minimum intensity peaks in adjacent frames thereby allowing this technique to be employed using non-synchronous light in video.
