Paper Abstract
DMD used as SLM modulation area array CCD design is proposed in the paper. It can Solve a problem in exposing
high-contrast scenes by ordinary CCD camera, with images appearing over-exposure or under exposure, bringing a loss
of the details of the photo. The method adoptes a forecast imaging scene, CCD is purposely designed by way of
more exposure regions and exposure times. Through modulation function of DMD micro-mirror, CCD is exposed with
sub-region and time-sharing, at the same time a purposely designed structure of image data enhances the area CCD
dynamic range. Experiments shows: This method not only improves visible quality of an image and clear details in the
backlighting or highlight, but also enhances the dynamic range of image data. The high-quality image and high dynamic
range data are real-time captured, the "fused" software is no longer required.
