摘要： A projection type image display apparatus (1) comprises a focus correction system (30). The system includes a temperature detection mechanism (16) for measuring temperature in the vicinity of a projection lens group (13), a correction amount calculation unit (18) for calculating a correction amount for correcting the focus shift caused by a temperature change, and a driving signal generation unit (19) for generating, based on the correction amount, a driving signal for driving a focus adjustment mechanism (15). If the user performs a focus adjustment using a focus operation input unit (23), a focus operation determination unit (21) determines that a focus adjustment has occurred independently of the focus correction system and changes a correction condition stored in a memory (20).

摘要： A projector, which projects color images using the three liquid crystal panels (41-43) while cooling them by the fans (611-613) for G, R, and B panels, comprises the level calculation unit (711) for finding the intensity levels of the R, G, and B components of image signals, the level calculation unit (721) for finding the voice levels of voice signals, the fan control unit (73) for controlling the numbers of revolutions of the fans (611-613), and the memory (761) for storing the cumulative amount of lighting time of the lamp (21). As the intensity levels get higher, the numbers of revolutions of the fans are increased, and as the cumulative amount of lighting time becomes larger, the numbers of revolutions of the fans are decreased. As a result, unnecessary noises caused by the fans (611-613) can be reduced while the liquid crystal panels (41-43) are properly cooled. Thus, the present invention has an object of reducing the noise of the fan which cools the display devices such as liquid crystal panels in a projector. Thus, the object of the present invention is to realize a reduction in noise caused by the fan for cooling a display device such as liquid crystal panels in a projector.

摘要： An illumination optics includes a plurality of light source sections for emiting light beams and a time sharing color separation device having a plurality of color filters. The color filters are rotationally moved so as to cross optical paths of the emitted light beams from the light source sections, thereby separate the emitted light beams to enter there into different color light beams in a time-sharing state. The reference axes of the emitted light beams to enter the time sharing color separation device are separated from each other, and the color filters are formed so that border lines of the adjacent color filters cross the reference axes approximately simultaneously at the time of rotation.

摘要： A projector includes a duct having a connecting end for connection to an air inlet provided in a housing, and an air intake end for drawing in outside air for cooling the interior of the projector. The duct is made of a soft or flexible material and is capable of altering its shape. Thus, the duct can change the position of the air intake end in space, for example, to different positions. Further, the duct is pivotable on a pivot axis, and thus can change the opening direction of the air intake end circumferentially about the pivot axis. Therefore, selection of the position and/or opening direction of the air intake end so as to draw in the outside air suitable for cooling the interior depending on the usage forms of the projector achieves efficient cooling of the interior of the projector.

摘要： In a projection-type display apparatus that directs light from a light source through the illumination optical system to a display panel so that an image displayed on the display panel illuminated by the light directed thereto is projected through a projection optical system onto a screen, an illumination optical system is used that has a light intensity uniformizing device of which the entrance surface is located at a first conjugate position substantially conjugate with the light source and of which the exit surface has a shape geometrically similar to the panel surface of the display panel and a reflection optical system for forming an image of the exit surface of the light intensity uniformizing device on the panel surface of the display panel. In the reflection optical system, every surface having an optical power is a reflective surface.
