  • Publication number: 20120001903
    Abstract: An display apparatus displays a three-dimensional image formed of a plurality of viewpoint images, and includes an image controller that controls a second viewpoint image to suppress a crosstalk of a first viewpoint image the first viewpoint image and the second viewpoint image are included in the plurality of viewpoint images. The image controller switches a control mode for suppressing the crosstalk, between a subtraction mode and an addition mode in accordance with an image input signal forming the three-dimensional image.

  • Patent number: 8050858
    Abstract: In a vehicle-mounted navigation system, an operating unit that operates the driver's seat side image and an operating unit that operates the passenger's seat side image had to be provided separately, which increased the number of operation buttons and the size of the navigation system device. In a vehicle-mounted navigation system that displays images in multiple directions, an operating direction detector detects which direction an operation was performed from, and a controller controls the vehicle-mounted navigation system based on a detection result of the operating direction detector.

  • Publication number: 20110193861
    Abstract: A three-dimensional sense adjusting unit displays three-dimensional images to a user. If a displayed reaches a limit of parallax, the user responds to the three-dimensional sense adjusting unit. According to acquired appropriate parallax information, a parallax control unit generates parallax images to realize the appropriate parallax in the subsequent stereo display. The control of parallaxes is realized by optimally setting camera parameters by going back to three-dimensional data. Functions to realize the appropriate parallax are made into and presented by a library.

  • Publication number: 20110157555
    Abstract: An image signal storing unit stores an image signal provided from the outside. An image processing unit appropriately processes the image signal stored in the image signal storing unit in accordance with the instruction from an adjusting unit. A projecting unit projects, onto a display area, light corresponding to an image created by the image processing unit. A display size determination unit computes the display size of the picture plane displayed on a screen based on an image captured by the camera provided adjacent to the projection-type video-image display device. The display size determination unit then determines whether or not the display size of the picture plane is equal to or larger than a predetermined upper-limit size.

  • Publication number: 20110115992
    Abstract: Projection display apparatus 100 is equipped with a cooling device 300, which comprises an air passage as the passage of the air and a heat absorber that cools off the air flows in the air passage, and a light source controller 220, which controls the amount of light irradiated on the optical elements (liquid crystal panel 50 and the like). The optical elements are provided in the air passage. When the heat absorber receives an operation termination instruction to terminate the operation of the apparatus itself, it will end the cooling of the air flowing in the air passage. the light source keeps emitting the light, even in a case of receiving the operation termination instruction.

  • Patent number: 7845802
    Abstract: An illumination apparatus includes a plate-like separation optical element having a dichroic surface and a PBS surface. The dichroic surface reflects green component light and transmits yellow component light. The PBS surface transmits P polarization component light and reflects S polarization component light. The separation optical element combines red component light entering from a certain direction and transmitted through the dichroic surface, with yellow component light entering from a different direction and reflected by the PBS surface, and leads a combined light towards a red liquid crystal panel. The separation optical element combines green component light entering from the certain direction and reflected by the dichroic surface, with yellow component light entering from the different direction and transmitted through the PBS surface, and leads a combined light towards a green liquid crystal panel.
