1. A method comprising: for each of a plurality of pixels representing an imaged scene, providing captured temporally-consecutive samples of image data, each captured sample having an exposure time that is different than an exposure time of other captured samples for the pixel, the captured samples for each of the pixels being temporally offset relative to the captured samples for at least another one of the pixels; for each of a plurality of time periods, generating a synthetic sample for each of the pixels by computing, for each synthetic sample, a combined intensity of the captured samples that fall within the time period for that pixel; for each of a plurality of different time periods, grouping synthetic samples from adjacent ones of the pixels; for each of the plurality of pixels, matching image data in a first one of the groups of synthetic samples with image data in a second one of the groups of synthetic samples by comparing the groups of synthetic samples obtained for different ones of the plurality of different time periods; and constructing video frames by combining image data from the respective captured samples based upon the matched image data from the first and second groups of synthetic samples.
