摘要： Each light path changing member forms a first light flux by reflecting a half of light flux emitted from a particular area (central area or peripheral area) of light source in one direction using a polarizing beam splitter, and forms a second light flux by reflecting the other half of light flux, which has passed through the beamsplitter, in the afore-mentioned direction using the first mirror. Then, each light path changing member transmits a half of a light flux emitted from the other light source and guided by the second mirror in the same direction as that in which the first light flux has been guided using the polarizing beam splitter, and superposes the light flux on the aforementioned first light flux, and reflects the other half of light flux, which has been reflected by the beam splitter, in the aforementioned direction using the first mirror, and superposes the light flux on the second light flux.

摘要： A lens mounting plate to which a projection lens unit is fixed is brought into contact with a sliding base. The lens mounting plate is pressed against the sliding base by the urging of a coiled spring. The pressing force is set such that the position of the projection lens unit can be held and shifted. A cover is provided with a pipe-shaped projection so as to surround the projection lens unit with a clearance corresponding to the shifting width of the projection lens unit between the pipe-shaped projection and the projection lens unit. A user shifts the position of the projection lens unit with his or her fingers laid on the pipe-shaped projection and the projection lens unit.

摘要： A projector comprises as mounted on a chassis a light source, a projection lens for projecting light on a screen, dichroic mirrors positioned on an optical path from the light source for separating light into R, G and B, and a relay lens disposed on the longest of optical paths of R, G, B and interposed between the dichroic mirror and the projection lens for causing the light on the longest path to reach the projection lens. An adjusting mechanism is mounted on the chassis for moving the relay lens upward, downward, leftward or rightward in a plane orthogonal to the optical path thereof. The relay lens is moved for adjustment to make the corresponding irradiating light to be incident on the liquid-crystal panel within a minimum required range of irradiation.

摘要： A video signal processing circuit inputs a video signal to perform processing such as frequency conversion as well as processing for generating data representing the APL (Average Picture Level) of a frame video for each frame period. A microcomputer functions as a dimmer arithmetic block to perform processing for generating dimmer data upon receipt of APL data, and functions as a lamp driver control block to perform processing for sending out a dimmer command to a lamp driver. The lamp driver receives the dimmer command, to control an amount of light emitted from a light source (a lamp).
