Abstract: A light emitting layer containing a fluorescent material is provided on the back surface of a liquid crystal panel. External light transmitted by the liquid crystal panel and incident on the light emitting layer causes the light emitting layer to emit light to illuminate the back surface of the liquid crystal panel. Moreover, the light emitting layer is formed as an anisotropic conductive light emitting layer in which the current flow is allowed only along the thickness of the anisotropic conductive light emitting layer. An electronic part for driving liquid crystal is mounted on the anisotropic conductive light emitting layer and connected to the electrodes of the liquid crystal panel through the anisotropic conductive light emitting layer.

Abstract: A display arrangement includes a memory for storing image signals of one field supplied to an LCD display section, a comparator for determining whether the image signals of the next field to be supplied to the LCD display are those for a fixed image display or a changing image display by comparing those image signals with the image signals of the preceding field stored in the memory, and a controller for controlling a display driver so that, when the comparator determines that the image signals are for a fixed image display, the driver drives the LCD panel in a reduced-power drive mode. In one embodiment, the reduced-power drive mode is a spread-out mode and, in another embodiment, the reduced-power drive mode is a low-voltage mode.

Abstract: A three-dimensional image reproducer receives a video signal including three-dimensional information including X and Y information constituting a plane and Z information constituting a depth. This apparatus causes particles to fall with respect to one line. The line from which the particles fall is changed in the Z direction based on the Z information. A light source generates a light beam toward the falling particle based on a video signal. The generated light beam is scanned in the X and Y directions. The focal point of the light beam is controlled to move in the Z direction in synchronism with the change of the line from which the particles fall. The image formed by the particles is viewed as a three-dimensional image if viewed from the Z direction.

Abstract: A signal processor alternately outputs two input signals to a common output terminal every predetermined period to form a single serial signal. A capacitor for holding the input signal is provided on each input signal transmitting path. A buffer is provided at each of the preceding and succeeding stages of each capacitor. The turning on and off of these buffers is controlled by a single switch. The switch is controlled so that when one capacitor is supplied with the input signal, the other capacitor outputs a signal.

Abstract: A display apparatus is provided which displays a natural image in accordance with the upward and downward direction of the display apparatus. The display apparatus is provided with an inclination detecting unit, a memory which stores data of an image which is wide in the upward and downward direction, and a controller which displays only a partial area of the image. The inclination detecting unit includes a light emitting device which emits light in a direction varying according to the direction of the display apparatus and light receiving devices whose directions are maintained constant due to the gravity irrespective of the direction of the display apparatus. The inclination detecting unit detects an inclination based on the light incident position on the light receiving device. The controller determines the position in the upward and downward direction of the image area to be displayed in accordance with the detected inclination.

Abstract: A distance sensor for detecting the distance between a display panel and an image viewer is provided on a display apparatus. An image signal supplied to the display panel is controlled based on the distance detected by the distance sensor to make a changeover between an enlarged image and a reduced image or between scrolling and stopping of a text or between moving and stationary display of a moving image. The speed of the scrolling and the speed of the moving display are stepwisely set according to the detected distance.

Abstract: A panoramic vision apparatus having a simple structure is provided which produces an image from which the viewer feels a natural stretch. A shooter and a display are each provided with a prism. The shooting range is changed by a rotation of the prism of the shooter and the projection position is changed by changing the direction of the projected light by a rotation of the prism of the display. The shooter outputs a direction signal representative of the direction of the prism of the shooter in synchronism with a video signal. The display sets the direction of the prism thereof in accordance with the direction represented by the signal to project an image.

Abstract: A compact outputter of a simple structure is provided without the back lighting function being deteriorated. A transparent electrode is exposed out of a first surface and a second surface through a through hole of an electro luminescence element. A driving signal output by an LSI chip is directed from a driving signal outputting aluminum electrode to a driving signal inputting transparent electrode through another transparent electrode. The driving signal is input to an LCD panel. Since the LSI chip is mounted on the second surface, the light from the electro luminescence element illuminating the LCD panel is not intercepted.

Abstract: A sample/hold circuit which receives a voltage level at the input terminal thereof at a specific timing, and outputs the received voltage level in the form of a hold voltage. The sample/hold circuit includes an analog-to-digital converter for receiving a voltage level at the input terminal thereof, a memory element for storing the received voltage level in the form of hold voltage data, and a digital-to-analog converter for outputting the hold voltage data. The sample/hold circuit may be fabricated into a one-chip integrated circuit. The memory element may be a nonvolatile and reprogrammable memory.

Abstract: To provide a three-dimensional vision camera where no disagreement is caused between two-dimensional image information and distance information, the three-dimensional vision camera is provided with a memory (11), a neural network (12) and a three-dimensional image synthesizer (13). In the memory (11), image data of a photographic object shot from different directions are stored. Information necessary for converting the image sensed by an image sensing device (2) into a three-dimensional image is read out from the image data of the memory (11) by the neural network (12). A three-dimensional image is produced by the three-dimensional image synthesizer (13).

Abstract: A memory is provided for storing one field of video signals supplied to a liquid crystal display panel serving as a display portion. Whether the video signals to be displayed have a stationary image portion or a moving image portion is determined by a comparator by comparing the video signals of the last field read out from the memory and the video signals of the present field supplied to the liquid crystal display panel. When it is determined that the video signals have a stationary image portion, the speed of scanning by a driver is reduced. When the scanning speed is low, the power required for the scanning is reduced.

Abstract: A three-dimensional vision camera where there is no disagreement between the video signal and the distance signal is provided by using the taking optical system for the distance measurement. A reflecting mirror 8 for reflecting a distance measuring laser beam from a laser diode 6 is arranged behind a taking lens 4. The laser beam is irradiated to a photographic object through the taking lens 4. The laser beam reflected by the photographic object is received by a photodiode array 7 through the taking lens 4 and the reflecting mirror 8. While the taking lens 4 is moved along the optical axis to perform photographing, the laser scanning is performed by rotating the reflecting mirror 8 about two axes vertical to the optical axis of the taking lens 4 to measure the distance.

The image light beam from the liquid crystal panel and the light beam from the light emitting device are projected onto the screen through the projector lens. The light beam from the light emitting device reflected by the screen is received through the projector lens and the prisms. A position controller moves the projector lens forward and backward while scanning the light beam from the light emitting device by the prisms.
