Synchronized lighting and video active lighting tracks (valt) with synchronized camera to enable multi-scheme motion picture capture

Abstract

A method and system for synchronizing LED lighting to the shutters of fast digital cameras. The system enables capture of multiple lighting schemes to be filmed in a single video take on sequential frames. Since 24 frames per second is the industry standard used broadly in film and television, a 96 FPS camera can capture up to 4 lighting tracks of 24 FPS each in a single take. Each lighting fixture can be changed frame by frame to any desired intensity. The changing of lighting can be synchronized with the times when the shutter is closed so that all frames are complete and are without the visual artifact of the light changing mid frame. This is extremely useful for simple visual effects such as a simulated camera flash, lighting pattern or gun flash. The lighting can be programmed so that by turning on lights at the appropriate intensity while the camera shutters are closed all viewers on set perceive a constant, flicker-free light. The entire system is compatible with existing industry standards.
