1. A computer-implemented process for generating high dynamic range (HDR) video from an image sequence captured while varying the exposure of each frame, said process comprising using a computer to perform the following process actions: setting the exposure for each frame of the video image sequence prior to it being captured as a function of the pixel brightness distribution; for each frame of the video after a prescribed number of initiating frames, identifying corresponding pixels between the frame under consideration and both preceding and subsequent neighboring frames representing a corresponding pixel set, for each set of corresponding pixels, identifying at least one pixel in the set that represents a trustworthy pixel and employing the pixel color information associated with the one or more identified trustworthy pixels to compute a radiance value for that set of pixels to form a radiance map representing a frame of the HDR video.
