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. The present invention provides for an algorithm for frame rate resampling providing a method for determining the mapping of input frames to output frames and a method for smoothly ramping the mapping of input frames to output frames based on interactive user input and a method for optimizing the alignment of input frames to output frames such that during areas of constant speed the alignment is optimally centered on the frames and a method for computing the weighting function for averaging input frames to output frames and a method for handling negative values in the weighting function in regions of bright highlights.

Abstract: First and second spatial frame regions are identified in a sequence of motion picture image frames captured at a high frame rate. Different motion blur parameters are determined for each of the first and second spatial frame regions. First and second intermediate frame sequences having frame rates less than the capture frame rate are generated from the original frame sequence. The first motion blur parameter is applied to the first intermediate frame sequence and the second motion blur parameter is applied to the second intermediate frame sequence. The first and second spatial frame regions in the corresponding first and second intermediate frame sequences are composited to produce an output frame sequence having different motion blur in different regions of the scene.
