    Abstract: An image display apparatus detects a projection angle of a projection unit that projects a screen image on a screen and is capable of vertically changing the projection angle, and corrects trapezoidal distortion of the screen image according to the projection angle. The image display apparatus changes the amount and direction of trapezoidal distortion correction based on the projection angle. The image display apparatus also determines whether a projection mode is projection upward to a wall or projection to a ceiling and changes the direction of trapezoidal distortion correction for projection upward to the wall and projection to the ceiling. Specifically, for projection upward to the wall, a correction factor is positive and an upper edge portion of the screen image is compressed for correction; and for projection to the ceiling, a correction factor is negative and a lower edge portion of the screen image is compressed for correction.

  • Patent number: 7789516
    Abstract: A thin projection type image display device with a low chin height includes a cabinet, a screen, a projection optical system, an optical path changing unit, and a reflecting unit. The screen is disposed on a front side of the cabinet. The projection optical system enlarges and projects an image formed by a display element, and the optical path changing unit is disposed on the bottom of the cabinet to reflect the image enlarged and projected by the projection optical system. The reflection unit is disposed obliquely to the screen and below the screen to reflect the image reflected by the optical path changing unit toward the screen. The projection optical system is disposed in a space above a horizontal plane perpendicular to the screen, behind the front side of the cabinet, and below an optical path of light incident on a bottom of the screen.

  • Publication number: 20080074625
    Abstract: A projection apparatus including an illumination system, a light valve, a first optical element, a first projection lens, and a second projection lens is provided. The illumination system is suitable to provide an illumination beam, and the light valve is disposed on a transmission path of the illumination beam. The light valve is suitable to convert the illumination beam into an image beam. The first optical element is disposed on a transmission path of the image beam. A portion of the image beam is reflected by the first optical element, and a remaining portion of the image beam passes through the first optical element. The first projection lens is disposed on a transmission path of the image beam passing through the first optical element, and the second projection lens is disposed on a transmission path of the image beam reflected by the first optical element.

  • Publication number: 20080055564
    Abstract: An interactive document camera system includes a document camera, a display panel, and a handwriting sensor module. The document camera can simultaneously output an image of an object and a handwriting input obtained from the handwriting sensor module. The inactive document camera system further includes a computer system so that an operating image provided by the computer system can be simultaneously outputted, and a handwriting data corresponding to the handwriting input can be recorded in the computer system. The interactive document camera includes an image-sensing and processing unit, different connecting interfaces and an image synthesizer. The different connecting interfaces are selectively connected to and communicated with a display panel, a handwriting sensor module or a computer system.

  • Patent number: 7329004
    Abstract: A rear projection display device improves the brightness by improving the utilization efficiency of image light projected to a screen from slantly below. At least a green component of the image light is P-polarized to the screen (7). Therefore, reflection of light on the screen (7) is reduced.
