Abstract: The present invention is a method of processing a sequence of frames from digital motion picture cameras to allow remapping of the time-base of the input frames to a new and possibly variable time-base in the output frame sequence. This invention provides a method that makes small adjustments to the user's specified positions to achieve optimal integer mapping from input frames to output frames in the integrated function.

Abstract: A stiffening strip at selected edges of a screen may enable the use and mounting of a high-elastic modulus substrate screen material. Such screen materials may be engineered to provide polarization-preserving characteristics, and be applied to or part of the high-elastic modulus substrate. Furthermore, the stiffening strip may enable the use of screen vibration techniques to reduce speckle in display applications that use projection screens, particularly those display applications using illumination sources prone to speckle such as laser-based projection. The screen vibration may be provided by a vibrating device attached to the stiffening strip.
