    摘要: A projector includes a liquid crystal light valve to which the image data is written in a line sequential manner, a polarization switching element for switching between the first and second polarization states throughout the switching areas in a line sequential manner, and a birefringent optical element for changing the light path of the incident light in accordance with the polarization state thereof. The boundary position between the switching areas of the first and second polarization states moves in sync with the boundary position between the first and second image data writing areas corresponding to the first and second sub-frame.

    摘要: When a history image display mode is performed, a display region of a display unit of a projector is divided into a plurality of windows. In a main window, an image based on a currently selected image signal is displayed. In a plurality of sub windows, history images as images based on image signals selected in the past are displayed in accordance with chronological order. When a user desires to switch an input image, the user uses a remote controller or a manipulation unit to perform a manipulation to select a desired history image on a screen of the display unit. When the manipulation to select a history image is performed, the projector selects an input terminal corresponding to the selected history image, and causes an image based on an image signal from the input terminal to be displayed in the main window.

    摘要: A light valve such as an active matrix LCD between crossed polarizers, utilizing, for instance, individual transistors to control each “pixel area” of the LCD and storage elements to store video signal data for each pixel, with optically shielded “dead spaces” between pixels to eliminate electric field cross-talk and non-information-bearing light bleed-through, is illuminated with a bright independent light source which creates a video image projected via specialized projection optics onto an internal or external screen without distortions, regardless of the angle of projection onto the screen. Use of heat sinks, IR reflective coatings, heat absorbing optics, optional fluid and a thermistor controlled pixel transistor bias voltage injection servo circuit stabilizes image performance, maintaining accurate color and contrast levels as the LCD changes temperature. In one embodiment of the invention, use of a multi-color LCD with a stepped cavity, producing different thicknesses of LCD for the different wavelengths that pass through it, allows a linear correspondence between the wavelengths passing through the LCD to produce true black, high contrast and CRT-like color rendition. A dichroic mirror arrangement is used to overlap differently colored pixels in the projected image. Use of striped mirrors duplicate pixels, where necessary, eliminating spaces between pixels, creating a continuous image with no apparent stripes or dots. A special venetian-blind type of screen is also disclosed and methods for using the system to view three-dimensional video are also explained.

    摘要: There is provided a video output apparatus which inputs a video content that can have at least three different resolutions. A format detector (112) detects an alteration of a resolution of a video content. A scaling processor (105) scales up the video content at a set scale ratio. Upon detection of an alteration of the resolution, the format detector (112) selects one of a plurality of supplemental video pictures, which are prepared in advance in a memory (113), in accordance with the degree of decrease of the resolution after the alteration to that before the alteration. An image composition unit (106) controls a display unit (110) to display the supplemental video picture together with a video associated with the video content via a video display unit (108). Even when the resolution decreases considerably, a decrease in user's convenience can be suppressed.
