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.

Broadcasting system and media player

A camera divides a light beam having passed through a taking lens unit into two light beams. One light beam forms an image on a silver salt film. Another light beam forms an image on a CCD. A light path for said another light beam is provided with an aperture diaphragm. The taking lens unit has an aperture diaphragm. Said two aperture diaphragms are correlatively controlled by a controller incorporated in the camera.

Camera

An image observation device which is so arranged that a user can look an image in through an ocular window thereof with the device being fitted to the user's head for example, that the image changes in linkage with movement of the user's head, and that unnecessary change of the image is prevented during the observation. The image observation device includes an eye access detector for detecting whether the user's eyes approach thereto or not, and includes, a controller by the operation of which the image changes in linkage with movement of the user's head only if the eye access detector detects that the user's eyes approach thereto, and by the operation of which the image does not change in linkage with movement of the user's head if the eye access detector does not detect that the user's eyes approach thereto.

Image observation apparatus

A head-mounted image display apparatus is provided with: an image display element; a projection optical system that projects an image displayed by the image display element, so as to be enlarged; a reflective screen onto which the image is projected by the projection optical system; and a combiner disposed between the projection optical system and the screen. The combiner transmits the image light from the projection optical system and directs it to the screen, and reflects the image light reflected at the screen and directs it to the user's pupil.

Head-mounted image display apparatus

An image display apparatus has an observation room for housing an observer, and the side faces, floor face, and ceiling face of the observation room are used as screens, onto which images displayed on a smaller number of image display devices than the number of screens are projected. At least one image display device displays, on a time-division or screen-division basis, images to be projected onto two or more screens so that images are projected onto all of the screens.

Image display system

A projector, which projects color images using the three liquid crystal panels ( ) while cooling them by the fans ( ) for G, R, and B panels, comprises the level calculation unit ( ) for finding the intensity levels of the R, G, and B components of image signals, the level calculation unit ( ) for finding the voice levels of voice signals, the fan control unit ( ) for controlling the numbers of revolutions of the fans ( ), and the memory ( ) for storing the cumulative amount of lighting time of the lamp ( ). 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 ( ) can be reduced while the liquid crystal panels ( ) 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.

Projector with fan controller

An image display apparatus has a signal input portion for receiving an image signal, an image compensator for electrically compensating the image signal for distortion so that a left and a right image displayed in an observer's left and right eyes have identical distortion and then outputting a left and right image signal that correspond to the left and right images, a signal switcher for switching between the left and right image signals output from the image compensator so as to output the left and right images alternately chronologically, a single two-dimensional image display device for displaying a two-dimensional image in accordance with the image signal output from the signal switcher, a pair of left and right eyepiece optical systems for directing image light exiting from the two-dimensional image display device to the observer's left and right eyes so that the two-dimensional image is displayed as a virtual image in the observer's eyes, and an optical path switcher for time-divisionally switching optical paths from the two-dimensional image display device to the observer's eyes in synchronism with switching between the left and right image signal output from the signal switcher so that the image light enters either the observer's left or right eye at a time.

Image display apparatus

A polished glass disk medium substrate suitable for use as a substrate for a hard disk, a hard disk containing the substrate and methods for making the substrate. The substrate containing glass forming raw materials may be formed so as to have a Young's modulus of 110 or higher.
