  • Patent number: 7959300
    Abstract: A projection image display device including a display plane for displaying an image, a projection mechanism projecting an image on the display plane, and an imaging mechanism arranged on the same side of the display plane as the projection mechanism for imaging the display plane. The imaging mechanism is arranged at a position where a position symmetric with respect to the display plane of the projection mechanism is out of the range of the field angle of the imaging mechanism. By arranging the imaging mechanism at a position where no direct reflecting light of the light source of the projection mechanism comes, it is possible to prevent generation of a hot spot.

  • Patent number: 7907150
    Abstract: A method of presenting multiple image sources of approximately registered images so that the mind can easily fuse the multiple images into one image. Improvement to fusing can be achieved by alternating views between sources at 85 hertz or more. The insertion of a black frame between the succession of frames optimizes the neurological functions of the human optical system (produces retinal decay) such that the perception of a useful fused image is greatly enhanced. Stereographic fusion can also be achieved to allow for fusion of loosely registered datasets.

    Abstract: In an information display apparatus such as a head-up display, while safety is being secured, visibility from a user is improved. Image data having an object such as an arrow showing an advancing direction or a road sign drawn on it are generated as information to be given to the user by a display information generating section 12 and is output to a projector 13. When a light beam R1 corresponding to the image data is emitted from the projector 13 to a combiner 14, reflected light of the light beam R1 and transmitted light of external light R2 are combined in the combiner 14, so as to be viewed by the user.

  • Patent number: 7898502
    Abstract: Variation of the wavelength of the light emitted from a light source is reduced by a wavelength variation reduction mechanism. Hence, wavelength deviation of the intensity peak of the light emitted from the light source from the diffraction-efficiency peak of a hologram optical element is reduced. Thus, even when a high-brightness light source is used, the light emitted therefrom can be diffracted with the hologram optical element efficiently. Moreover, the heat generated by the light source is efficiently rejected through the surface of a land portion of a flexible printed circuit, is then, via an insulating layer of the flexible printed circuit, efficiently absorbed through the surface of a heat absorbing member, and is then, via a shield conductor, led out of a casing, so as to be thereby expelled.

    Abstract: A display system for displaying information to a vehicle operator comprises one or more projectors positioned in an operator cab of a vehicle. The projector is configured to project a heads up display of a plurality of data sets on a windscreen of the vehicle. Projected data sets are positioned in the heads up display and/or moved within the heads up display based on assessed relative priority levels of the data sets. Thus, for example, a data set with a higher assessed relative priority level may be positioned in a location of greater operator viewing prominence. If the priority level drops, the data set may be moved to a position of lower operator prominence. Respective heads up displays may be projected on more than two separate windscreens of the vehicle, either simultaneously or at alternate times, and possibly depending on an operational mode of the vehicle.

In addition, a second virtual image is set based on the information of location and orientation of the real object, and a second image superimposing step superimposes the second virtual space image onto the superimposed image generated in the first image superimposing step without considering the occlusion, wherein the second virtual space image is an annotation associated with the real object.

    Abstract: A multiplex image display device prevents onscreen input buttons from appearing at the same positions. A “command area” refers to an area of the display screen where the user can enter a command for manipulating one of images being simultaneously displayed on the single display section for individual viewing from different directions. In the multiplex image display device, the positioning control section controls the positioning of the command areas so that a command area for one of the images being simultaneously displayed on the display section is displayed at a different (i.e., non-overlapping) position on the display section from a command area for another one of such images.

  • Patent number: 7586487
    Abstract: The vertical selection circuit of the imaging apparatus selects a selection line, a first shutter line, and a second shutter line to divide a single frame into three parts at arbitrary ratios. A first output signal is generated during a period from the first shutter line to the second shutter line and a second output signal generated during a period from the second shutter line to the selection line. By mixing the two output signals described above, an image with a large dynamic range can be obtained.

  • Patent number: 7549775
    Abstract: Directivity of light beams can be adjusted appropriately relative to the normal to the light emission surface of a light source. Thus, the light source apparatus has high brightness without significant unevenness in illumination with its simple structure. The light source apparatus comprises a light source substrate on which plural light sources are arranged, a secondary light source member on which a secondary light source surface is formed when it receives light from the plural light sources, and frame that supports the light source substrate and the secondary light source member from their lateral sides so that they are opposed to each other. At least a pair of side surfaces of the frame has reflection surfaces opposed along the arrangement direction of the plural light sources, and the reflection surfaces that the pair of side surfaces has are inclined to the same direction relative to the light source substrate.

  • Patent number: 7551184
    Abstract: There is disclosed a highly convenient user interface which can suitably perform enlarged display of a designated object and suitably allow the user to operate original objects occluded under the object which undergoes the enlarged display or the like. An arbitrary position on a reduced image displayed on a screen of a display unit is designated using a pointer. A pointer sensing unit determines whether or not the designated position falls within the display range of the reduced image, and an enlarged image corresponding to the reduced image is displayed at a position according to the designated position of the pointer within that region.

  • Patent number: 7551067
    Abstract: An object of the present invention is to detect a three-dimensional object by use of a single-eyed camera with a higher degree of accuracy by eliminating false detection of an obstacle, which is caused by a detection error of a vehicle speed sensor or that of a rudder angle sensor. A top view of a first image including a road surface image is created. The first image is imaged by a camera mounted to a vehicle. Then, a top view of a second image is created. The second image is imaged at a timing different from the timing when the first image is imaged. The two top views are associated with each other on the basis of a characteristic shape on the road surface. In each overlapped portion of the two top views, an area in which a difference occurs is identified as an obstacle.

  • Patent number: 7505841
    Abstract: A vehicle restraint system has a vision-based occupant classification system for control of airbag deployment during a crash scenario. The classification system utilizes two imaging sensors which together create a stream of paired images received and stored by an occupant classification controller. A computer program product of the controller utilizes the paired images to extract disparity/range features and stereo-vision differential edge density features. Moreover, the controller extracts wavelet features from one of the two paired images. All three features or maps are classified amongst preferably seven classifications by algorithms of the computer program product producing class confidence data fed to a sensor fusion engine of the controller for processing and output of an airbag control signal input into a restraint controller of the vehicle restraint system.
