A high speed pulse width modulation system for driving a linear array spatial light modulator, including: a pixel-serial data source that provides at least one or more pixel-serial input data streams; a fundamental system clock signal; phase-shifted versions of the fundamental system clock signal; and a serial-to-parallel converter for converting the at least one or more pixel-serial input data streams into one or more pixel-parallel data streams. Also included is a decoder for decoding data of a single input pixel into at least two or more related pulse width modulation (PWM) signals, and a circuit for combining the at least two or more PWM signals into a single PWM signal capable of driving one of a plurality of inputs on a linear array spatial light modulator.

High-speed pulse width modulation system and method for linear array spatial light modulators

A digital mastering system for processing digital image signals originating from scanned motion picture film includes a film scanner for scanning motion picture film and generating a stream of digital image signals corresponding to motion picture images, a color grading channel that pre-visualizes a certain 'look' that can be applied to the digital image signals and a digital rendering channel that renders the digital image signals pre-visualized for a certain 'look' into a digital master. The &#x201c;look&#x201d; includes the appearances produced by either a standard motion picture print film and/or adjustments applied to a standard appearance to obtain a creative effect. The color grading channel includes a parameter generator for storing parameters for a plurality of &#x201c;looks&#x201d;, a digital color grading processor for applying one or more selected parameters to impart a pre-visualized &#x201c;look&#x201d; to the digital image signals and a display device capable of reproducing the color graded signals. The digital rendering channel includes a digital rendering processor for applying one or more of the parameters selected by the parameter generator to the digital image signals in order to impart the rendered &#x201c;look&#x201d; into the digital image signals and a digital mastering device for producing a digital master from the rendered digital image signals.
