    摘要: A video projector includes a display device which receives an image signal and generates image light projected onto a projection surface. A scaling processor scales the input image signal. An OSD processor generates and corrects an adjustment pattern image in accordance with a correction instruction on the projection surface. An image signal synthesizer combines the image signal processed by the scaling processor with an OSD image signal generated and corrected by the OSD processor to generate a combined image signal. A trapezoidal distortion corrector performs trapezoidal distortion correction on the combined image signal from the image signal synthesizer based on the correction of the adjustment pattern image on the projection surface. The adjustment pattern image generated by the OSD processor includes a reference quadrangle pattern and downsized quadrangle patterns, which are reduced in size from the reference quadrangle pattern.

    摘要: At the time of manual adjustment, a motor driving signal corresponding to a user's key operation is fed to a focusing motor from a microcomputer through a switch. At the time of automatic adjustment, the switch selects a motor driving signal from a sensor and feeds the selected motor driving signal to the focusing motor. The sensor contains a dedicated microcomputer. The dedicated microcomputer samples an image pick-up signal of a CCD line sensor in the sensor to generate contrast data, and automatically drives the focusing motor, to automatically make focusing adjustment.

    摘要: A microcomputer performs image drawing processing of a projection video for adjustment by an OSD (On-Screen Display) circuit when it detects the press of an adjustment command key. The projection video for adjustment is an image having a black-and-white area high in contrast formed therein. The projection video for adjustment is picked up by a CCD line sensor in a sensor. A microcomputer has its input an image pick-up signal from the CCD line sensor, to make focusing adjustment and trapezoidal distortion correction on the basis of the image pick-up signal.

    摘要: An image display device capable of preventing erroneous activation of the theft prevention function is provided. The image display device includes a theft prevention unit having an alarm function for preventing theft of the image display device, and a control circuit for controlling the theft prevention unit. The control circuit invalidates the alarm function of the theft prevention unit before the image display device is shipped out of a factory.
