Abstract
A video signal is recorded on unexposed cinematographic film by shining light from a light source onto a deformable mirror device (DMD), which comprises a micro-mechanical array of electronically-addressable mirror elements, the elements corresponding to individual pixels. The elements of the DMD are controlled or modulated in response to the video signal. Light is selectively reflected by the DMD onto an image plane containing the film such that the light reaching the film is representative of the video signal.
