  • Patent number: 7623111
    Abstract: The invention is intended to change the viewing angle in accordance with a viewer's intention. Disposed between a light source (810) and a liquid crystal display panel (804), a Fresnel lens (812) converts light coming from the light source (810) to approximately parallel light and allows plural images to be displayed to different positions. The light source (810) is configured in such a manner that lighting positions and lighting regions can be changed. Lighting control means for changing the lighting positions or lighted regions of the light sources (810) is provided.

  • Patent number: 7489319
    Abstract: A highly precise and durable light source device 50 for a three-dimensional display does not use a mechanical construction and thus can rapidly move an illuminating point on a light source to a position that best matches the positional movement of an observer. The light source device has an image display means 52 that creates an image using transmitted light. The LED arrays 51U, 51D of white LEDs 1 are arranged in two tiers and display a right-eye image and a left-eye image, respectively. The light source device also has an LED control means 53 that performs a turn-on control on the white LEDs 1 in the LED 51U, 51D.

  • Patent number: 7355658
    Abstract: An image display in which, even when an observer moves vertically in a position viewing an image, a bright image is obtained. There are provided a liquid-crystal display panel (804) capable of transmitting light projected from backward, a light source (801) for projecting a first light as a particular polarization of light and a second light orthogonal in polarization axis to the first light to the liquid-crystal display panel (804), and a stripe-patterned filter (802) arranged between the liquid-crystal display panel (804) and the light source (801) and having, repeatedly in a given direction, first areas for transmitting the first light and second areas for transmitting the second light. The light source is structured by including light emitters (810) for emitting red, green and blue lights, to sequentially emit red, green and blue lights from the light emitters (810).

  • Publication number: 20070008404
    Abstract: When displaying a stereoscopic image, in order to display a natural stereoscopic image such that an area other than an area of attention is not displayed ahead of the focused area, an area of attention to be clearly displayed where an object to be focused exists is specified at a time of displaying two images to make a stereoscopic image, and gradation processing is performed on an area other than the area.

  • Publication number: 20060293606
    Abstract: We provide quite a novel personal authentication system using heart sound waveform and/or breathing waveform pattern which promptly judges personal authentication of a person to be authenticated with a very high degree of accuracy. The personal authentication system is comprised of a waveform detection means which detects a heart sound waveform pattern and a means which compares a heart sound waveform pattern detected by the waveform detection means with a previously registered heart sound waveform pattern. If the detected heart sound waveform pattern coincides with the registered heart sound waveform pattern, the system authenticates the person to be identical. In such constitution, the system can check the autonomic heart sound which cannot be controlled by a personal will based on the previously registered heart sound waveform pattern in real time, and performs personal authentication of the person to be authenticated with very high accuracy promptly.
