Abstract
An apparatus and method for generating video signals using an improved camera system is disclosed. Video recording techniques which save bandwidth, and a temporal filter which is tailored to the eye's temporal response are also disclosed. In the camera apparatus, an optical means directs light from a scene to both a first video imaging device operating at a relatively fast frame rate and a second video imaging device operating at a relatively slow frame rate. The outputs of the two video imaging devices can be combined to obtain a high definition video signal.
