    摘要： An automatic keystone correction which enables even an inexperienced user to easily obtain an image corrected using the keystone distortion during a tilted projection. The projector detects varying of its elevation angle by using an elevation detecting module. When the angle stops varying, the projector determines that the elevation adjustment by the user ends, and executes auto keystone correction of the input image according to the elevation angle.

    摘要： To provide a technique for facilitating control of a plurality of projectors. A projection display system comprises a plurality of projectors wherein a plurality of images projected by the projectors are displayed on a common projection screen. Each projector comprises: a control signal processor for processing a control signal given from an external device and generating a processed control signal; and a signal input/output section for input/output of the control signal and the processed control signal. The plurality of projectors are coupled in a cascade connection, by interconnecting the signal input/output sections of the projectors. The control signal and the processed control signal include connection sequence data indicating the cascade connection sequence. The control signal processor of each projector comprises a memory for storing, on the basis of a given control signal, a connection sequence when the projectors are coupled in a cascade connection.

    摘要： In a two-dimensional optical deflector apparatus comprising an optical deflector and a driver for driving the optical deflector, the optical deflector includes a mirror, a first piezoelectric actuator for rocking the mirror with respect to a first axis of the mirror, and a second piezoelectric actuator of a meander type for rocking the mirror with respect to a second axis of the mirror perpendicular to the first axis. The driver generates a curved-type saw-tooth drive voltage and applies the curved-type saw-tooth drive voltage to the second piezoelectric actuator.

    摘要： A projector that includes: a light source; a light-on/off unit that turns on or off the light source; a recording medium reproduction unit that reproduces information recorded on a recording medium, and outputs a video signal; a video signal processing section that converts the video signal provided by the recording medium reproduction unit, and generates a projection-video-use video signal; a light modulation unit that modulates a light coming from the light source based on the video signal generated by the video signal processing section, and emits a resulting video light; a projection system that includes a projection lens, and magnifies and projects the video light coming from the light modulation unit; a lens cover that opens and closes the front of the projection lens; a lens cover open/close detection sensor that detects an open/close state of the lens cover; and a control section that at least controls operation of the light-on/off unit and that of the recording medium reproduction unit. In the projector, the control section turns off the light source, and interrupts reproduction by the recording medium reproduction unit when the lens cover open/close detection sensor detects a state change of the lens cover from open to close, and turns on the light source, and starts reproduction by the recording medium reproduction unit in accordance with predetermined requirements when the lens cover open/close detection sensor detects a state change of the lens cover from close to open.
