Abstract
The present invention comprises methods and apparatuses for causing a single imaging lens system to simultaneously form multiple high resolution images on multiple imaging sensor planes. The images are preferably substantially identical, with no parallax error, except for different light levels so that the multiple images are of sufficient quality and similarity that they may be compared and/or combined (typically pixel-by-pixel) to create a single instantaneous high dynamic range (HDR) image. The invention may be used to create high-resolution HDR snapshots of moving subjects, as well as high-resolution HDR moving pictures (e.g. cinematographic films, movies, or other video) in which the subject and/or camera is moving. Alternatively, the images are substantially identical, or substantially identical except for different focuses.
