摘要： A projection system for etendue utilization includes a first light source configured to emit a light, the light including a first etendue component and a second etendue component, wherein the first etendue component has a lower etendue than the second etendue component, a first projection optics configured to project a first image on a screen, a second projection optics configured to project a second image on the screen, and an etendue splitter component. The etendue splitter component is configured to receive the light from the light source, extract, from the light, the first etendue component and the second etendue component, provide the first etendue component to the first projection optics, and provide the second etendue component to the second projection optics.

摘要： A dual projection system utilizes a first projector and a second projector to project alternating left and right channel images of a 3D display. The projectors are inversely synchronized such that while the first projector projects a right channel image the other projector projects a left channel image. A projection filter in each projector has left channel properties when the image being projected is a left channel image and right channel properties when the image being projected is a right channel image. The images projected from each projector alternate between left and right channel images approximately once per frame.

摘要： The color gamut of display devices like digital projectors and digital displays is expanded by incorporating additional passband filters into the optical path of the devices to produce presentations of color components in two different color gamuts. The composite visual effect of the two presentations is a presentation in an expanded color gamut. Special considerations in the modulation of color components of the image can reduce variations in color and brightness, which can otherwise manifest themselves as flicker.

摘要： Dual and multi-modulator projector display systems and techniques are disclosed. In one embodiment, a projector display system comprises a light source; a controller, a first modulator, receiving light from the light source and rendering a halftone image of said the input image; a blurring optical system that blurs said halftone image with a Point Spread Function (PSF); and a second modulator receiving the blurred halftone image and rendering a pulse width modulated image which may be projected to form the desired screen image. Systems and techniques for forming a binary halftone image from input image, correcting for misalignment between the first and second modulators and calibrating the projector system - e.g. overtime - for continuous image improvement are also disclosed.

摘要： A filter wheel having spirally shaped left and right channel 3D filters. The 3D filters are, for example, spectral separation filters. The filter is mounted, for example, close to an integrating rod output of a projector. The left and right channel filtered light scrolls across a modulation device which is energized with correspondingly scrolling left and right image data. In one embodiment, the integrating rod comprises mirrored surfaces to facilitate recycling of light reflected off the filter wheel. The filter wheel may be placed in a single or dual projector configuration. In one embodiment, the filters are fixed at the end of an integrating rod using "re-cycled" light to illuminate different channels of a projection system.

摘要： Analog soundtracks (LT, RT) are recorded on a single one of the three dye layers present in a tri-pack color motion picture film, one of the same dye layers that is used for the color picture information. The single dye layer, preferably the cyan dye layer, is read out using a narrow spectrum, substantially monochromatic light source, preferably a red light-emitting diode (LED) (56), the spectrum of which is such as to be maximally absorbed by the dye layer and to remain well within the absorption range of the dye layer even when the dye layer color characteristics vary among film batches. The resulting lower-cost and environmentally-safer silverless analog audio sound tracks (LT, RT) have playback characteristics extremely close to conventional analog audio soundtracks prepared with silver.
