A system and process for generating High Dynamic Range (HDR) video is presented which involves first capturing a video image sequence while varying the exposure so as to alternate between frames having a shorter and longer exposure. The exposure for each frame is set prior to it being captured as a function of the pixel brightness distribution in preceding frames. Next, for each frame of the video, the corresponding pixels between the frame under consideration and both preceding and subsequent frames are identified. For each corresponding pixel set, at least one pixel is identified as representing a trustworthy pixel. The pixel color information associated with the trustworthy pixels is then employed to compute a radiance value for each pixel set to form a radiance map. A tone mapping procedure can then be performed to convert the radiance map into an 8-bit representation of the HDR frame.       Recently Added Patents Ink jet recording apparatus, and ink jet recording method Secondary battery Heated fuel injector system Tal effector-mediated DNA modification Process for amplifying DNA in cells File sharing method, computer system, and job scheduler Method of providing an operating voltage in a memory device and a memory controller for the memory device   Randomly Featured Patents Isolation trench with rounded corners for BiCMOS process Compact type belt microprinter Step for climbing wall surface Zoom lens device adapted to macro photography Scrub brush for flat and cornered surfaces Optical information recording medium Aromatic sulfonamide sulfonyl chloride compounds Method, apparatus, and system for remote client search indexing Electronic fluorescent lamp starter Multiprocessor system including processor cores and a shared memory © 2006-2008 PatentGenius.
