Abstract
A digital micro-mirror device (DMD) format conversion system for outputting a stereoscopic encoded optical signal using a DMD and a color wheel is provided. The DMD format conversion system includes a 3D data formatter for receiving an input signal and a DMD data formatter for receiving an output signal having stereoscopic image information and control information from the 3D data formatter and for outputting a DMD output signal having stereoscopic image information and control information. A color wheel control signal and output digital micro-mirror device data are synchronized based on an output frame rate generated by the 3D data formatter independent of the original input frame rate.
Claims9
A digital micro-mirror device (DMD) format conversion system for outputting a stereoscopic encoded optical signal in a format readable within a display system employing a DMD and a color wheel, said DMD format conversion system comprising:
- a 3D data formatter for receiving an input signal having stereoscopic image information with an input frame rate and generates an output signal comprising stereoscopic image infbrmation and control information having a self synchronized output frame rate independent of and decoupled from the input frame rate;
- a DMD data formatter for receiving the output signal having stereoscopic image information and control information from the 3D data formatter and for outputting a DMD output signal having stereoscopic image information and control information,
- wherein the DMD output signal having stereoscopic image information and control information, including a color wheel control signal indicative of rotation rate and output digital micro-minor device data indicative of micro-mirror switching rates, wherein said color wheel control signal and output digital micro-mirror device date are synchronized based on the output frame rate generated by the 3D data formatter;
- said digital micro-mirror device data formatter including
- a dual port memory controller that converts the output signal having stereoscopic image information and control information from the 3D data formatter, with a full color image format, at the output frame rate into an image stream having serial individual color images synchronized to the color wheel control signal based on the output frame rate
- a memory device;
- a DMD data converter for formatting from die image stream into output DMD data readable by a digital micro-mirror chip;
- and
- a micro-controller for controlling the dual port memory controller based on the 3D format.
