    摘要： According to exemplary embodiments of the present invention, in a projections lens position adjuster, when a part of a dial exposed from an exterior case is rotated downward, a gear is rotated in an R2 direction. A Y-slider is then moved downward (in a Y3 direction). Accordingly, a Y-table is moved downward, as is a projection lens. When the part of the dial exposed from the exterior case is rotated upward, the projection lens is moved upward. When a part of a dial exposed from the exterior case is rotated leftward. In contrast, when the dial is rotated rightward, the projection lens is moved rightward. Provided around the projection lens are a first light shield for closing a gap between an opening of a front case and a periphery of the projection lens, and a second light shield for closing a gap between the projection lens and a hole of a base of the projection lens position adjuster. A shield body of the first light shield includes a ring-shaped elastic member disposed to extend between a ring and the projection lens, and a pair of attachments extending from the elastic member outward.

A Y-slider is then moved downward (in a Y3 direction). Accordingly, a Y-table is moved downward, as is a projection lens.

    摘要： When a video signal is inputted to a projector (10) through a video input terminal, a luminance peak value of an image of the video signal is detected by an image-analyzing circuit (61) to be outputted to a CPU (71). A gain-adjusting circuit (63) adjusts a luminance signal in the video signal based on a command from the CPU (71). The CPU (71) determines a gain adjustment amount based on the luminance peak value of the image obtained by the image-analyzing circuit (61) and outputs the result to the gain-adjusting circuit (63). For instance, when the luminance peak value (Ip) of the image is 50% of the upper limit (Imax) thereof, a gain-adjusting amount AG is doubled. In this case, an illuminating light volume of a light valve (44a) has to be reduced to 50%, which is achieved by light-attenuation by a light-source lamp (21) and an open/close light shield (23).
