    摘要: Methods and devices (400, 500) for capturing at least one digital image (550) are described. In one implementation, transmission of input light is modulated (410) onto the same pixel elements of a digital image sensor (420), comprising pixel elements. Frames of an image are captured having different exposures (440A, 440B, 440C) from the modulated transmission of the input light using the digital image sensor (420). The different exposure frames of the image are processed to produce a high dynamic range digital image (450). In another implementation, a portion of the input light is transmitted onto the same pixel elements of respective digital image sensors (530, 532) to produce frames (560A, 560B) of an image (550) having different exposures. The different exposure frames (560A, 560B) of the image are processed (540) to produce a high dynamic range digital image (570).
