Abstract:
This invention provides a system and method captures a moving image of a scene that can be more readily de-blurred as compared to images captured through the above-referenced and other known methods operating on an equivalent exposure-time interval. Rather than stopping and starting the integration of light measurement during the exposure-time interval, photo-generated current is switched between multiple charge storage sites in accordance with a temporal switching pattern that optimizes the conditioning of the solution to the inverse blur transform. By switching the image intensity signal between storage sites all of the light energy available during the exposure-time interval is transduced to electronic charge and captured to form a temporally decomposed representation of the moving image. As compared to related methods that discard approximately half of the image intensity signal available over an equivalent exposure-time interval, such a temporally decomposed image is a far more complete representation of the moving image and more effectively de-blurred using simple linear de-convolution techniques.
