  • Patent number: 8982192
    Abstract: Three-dimensional visual information may be displayed on curvilinear display surfaces. The display devices can include a control system configured to execute various methods for obtaining the visual information and displaying the visual information on the curvilinear display surface. If the visual information is intended for display on a first display surface, the control system can modify the visual information for display on the curvilinear display surface. The control system also can modify the visual information based upon relative positions and orientations of a viewer, projector, and/or the display surface, as well as to correct for anticipated environmental or optical interference. The control system outputs the visual information or modified visual information to a display device for display on a curvilinear display surface.

    Abstract: A portable image projection device has a housing with first and second members pivotable between device folded and unfolded positions. First lens optics mounted within the first member are configured for projecting light modulated by a spatial light modulator along an optical axis through a first aperture with a first throw ratio with the device in the folded position. A second lens optics element movably mounted within the first member is configured for selective movement between positions of non-intersection and intersection with the optical axis. The second lens optics element is configured for cooperating with at least part of the first lens optics for projecting the light modulated by the spatial light modulator along the optical axis through a second aperture with a second throw ratio less than the first throw ratio with the device in the unfolded position.

  • Patent number: 8823876
    Abstract: An image processing apparatus having an input unit for inputting an image signal and an image corrector for correcting the input image signal is disclosed. The image corrector is arranged to extract from the input image signal a specular reflection component and a diffuse reflection component and generate a corrected image signal based on a computation result with respect to these specular and diffuse reflection components thus extracted. This image corrector is adaptable for use in various types of image processors, including projectors, display devices and imaging devices.

  • Patent number: 8801192
    Abstract: A light source module and a projector using the same are provided. The light source module includes a monochromatic light source emitting a monochromatic light, a rotating wheel having a light transmitting area and a wavelength transforming area, a filter wheel rotating at a same rotation speed with the rotating wheel, and a dichroic mirror disposed between the rotating wheel and the filter wheel. The wavelength transforming area is coated with a first wavelength transforming material capable of transforming the first color light into a second color light. The filter wheel has a first color filter area and a second color filter area respectively corresponding to the light transmitting area and the wavelength transforming area. The dichroic mirror reflects the first color light to the rotating wheel and allows the second color light to transmit therethrough.

    Abstract: There is provided a light source device which, when a light source which excites a phosphor with excitation light and emits fluorescent light is used, reduces incidence of the excitation light to an excitation light source to increase an output of the excitation light and extend the life. The light source device is provided with a plurality of excitation light sources emitting excitation light and a phosphor changing excitation light to fluorescent light, and the excitation light sources are arranged so that each excitation light emitted from each of the excitation light sources asymmetrically enters an excitation light irradiation region on a phosphor. A mirror is installed on an optical path of unconverted excitation light reflected from the phosphor and returns the unconverted excitation light to the phosphor side, whereby the unconverted excitation light can be utilized as excitation light again.

  • Patent number: 8786788
    Abstract: A method is disclosed herein that derives a post-alignment transform that is applied to the input source after the application of an alignment transform to ensure that when each source illuminates the screen, the display is aligned and retains the correct displayed aspect ratio. The transform takes into account the alignment transform and the input source aspect, and then performs a secondary, post-processing transformation that corrects the distortion induced by the alignment transform. This aspect-preserving function is a linear transform that maps pixels in the aligned space to the aligned and aspect-correct space and can be applied to the input signal after the first alignment transform, or, in the case where the alignment transform is also linear, transforms can be directly combined to derive a compound multi-projector, aspect preserving transform. In this way, the input signal to the projectors will be aligned as well as retain proper aspect.
