摘要： , Provided are several apparatus and methods to attenuate illumination light in a projector. Illumination light may be attenuated by directing polarized light toward a liquid crystal (LC) attenuation panel. The panel selectively modulates some, all, or none of the polarized light passing through. The light from the panel is then directed toward a polarization device. The polarization device analyzes the polarized light, and allows or denies the light to pass therethrough based on the polarization of the light.

摘要： An image projection system (10) and method is presented for optically projecting an image onto a display surface (20) with visually correct geometry and optimum image quality. The projection system (10) includes an image processing unit (12) for receiving the input image data and generating distortion-compensated image data to compensate for ensuing spatial distortions in the projection system, a projection light engine (14) for receiving the distortion-compensated image data and projecting a distortion-compensated optical image that corresponds to the distortion-compensated image data; and, an optical reflection assembly (16) comprising at least one curved mirror (39) positioned in the optical path of the distortion-compensated optical image emerging from the projection light engine for producing a displayed optical image with reduced distortion on the display surface (20).

摘要： Embodiments of the invention provide a circuit for peaking video signals to be provided to a dynamic range limiter for displaying images on a display device. The circuit comprises a peaking filter including a filter input configured to receive a video signal. A first filter output provides a peaking signal for the video signal. A second filter output provides a peaked video signal based upon the peaking signal. The circuit further comprises a throttle circuit including a throttle input coupled to the second filter output. A throttle output provides a throttle signal based upon the peaked video signal. A scaler is coupled between the first filter output and the dynamic range limiter. The scaler is further coupled to the throttle output. The scaler adjusts the peaking signal based upon the throttle signal. Accordingly, peaking is adaptively applied to the video signal based upon the dynamic range limits of the dynamic range limiter, as well as variations in brightness of the input signal over portions of the displayed image.

摘要： A feature detecting circuit 4 detects an average luminance, a white area value and a black area value of a video signal, and a control circuit 5 controls a contrast adjusting circuit 2 such that a contrast gain of the video signal is more moderately increased than decreased according to changes of the detected average luminance, white area value and black area value. As a result, a good video quality can be obtained upon both increasing and decreasing the contrast gain of the video signal to adjust the contrast of the video signal.

摘要： Integrated processing of multimedia signals can eliminate unnecessary signal processors and converters without losing the functionality of typical home entertainment system components. The integrated system includes a main player that captures and processes signals digitally, a dummy display, and a dummy speaker. The dummy display may only have a display panel and a panel driver. The dummy speaker may only have a driving unit and no crossover logic. The main player may have a PC architecture and process all signals digitally for outputting signals tailored for the display device and the individual driving units of the dummy speaker. The integrated system may generate parameters for optimizing display of a video source. These parameters can be shared among users over a network connection.

摘要： A projection type display device and a method for controlling the same are capable of preventing a reduction in the brightness of video caused by an ineffective region. The method includes the steps of determining effective and ineffective video regions of video based on a brightness of an input video signal, calculating an average brightness value of the effective video region, and controlling an optical output of the projection type display device based on the calculated average luminance value.
This allows the correct brightness to be set when a displayed image does not utilize the entire area of the display.
