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： An illumination optical system has: a light source, a first optical member, a second optical member, and a rod integrator, and illuminates an image display surface of a display element. The light source emits illumination light having a flat beam cross section. The first optical member reduces flatness of the beam cross section. The second optical member condenses or diverges the illumination light. The rod integrator uniformizes spatial energy distribution of the illumination light subjected to optical action of the first and second optical members.

摘要： Broadcasting waves transmitted from a broadcasting device include operation control information for operating peripheral devices on a receiver side in accordance with the contents of a broadcast program in addition to broadcast data about said broadcast program. The receiver outputs the broadcast data to a display device, and transmits an operation command signal dependent on the operation control information to the peripheral devices to operate the peripheral devices in accordance with the contents of the broadcast program. As a result, an air conditioner raises or lowers room temperature and an illumination device blinks according to the progress of the program.

摘要： A dichroic film formed on a prism base member contains 10% by volume or more of a high-thermal-conductivity substance having a thermal conductivity of 20 W/mK or more at a temperature of 300 K. Preferably, the dichroic film is composed of high- and low-refractive-index layers laid alternately on one another, and the low-refractive-index layers contain 20% by volume or more of the high-thermal-conductivity substance. For lower angle-of-incidence dependence and higher light use efficiency, preferably, the following conditions: NL ≧1.58 and NH/NL≧1.33, where NL represents the refractive index of the low-refractive-index layers, and NH represents the refractive index of the high-refractive-index layers.

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 has a liquid crystal display panel for displaying an image, a lamp for illuminating the liquid crystal display panel, and a projection optical system for projecting light modulated by the image displayed. The lamp is held by a member whose position is variable to allow fitting of different types of lamp. The projector acquires data related to the lamp currently fitted and controls the light emission of the lamp on the basis of that data. The data includes the life of the lamp, so that the projector prevents the lamp to be lit longer than its remaining life. The remaining life is updated in accordance with how long the lamp has been lit. In addition to the lamp that is lit, an auxiliary lamp may be fitted so that the lamp that is lit can be switched to the auxiliary lamp as required. The lamp is formed into a single lamp unit together with a reflector or a casing to prevent the user from touching the lamp. The lamp is accessible for replacement only when it is in a predetermined position, where the lamp is never allowed when hot.
