| 20090040402 | LIQUID CRYSTAL PROJECTOR AND CONTROL METHOD FOR LIQUID CRYSTAL PROJECTOR - A liquid crystal projector which projects a three-dimensional imaged based on image signals for the left and right eyes including: a liquid crystal panel into which an image for the left or right eye is written in a one-field time period based on the image signal; an optical shutter has a plurality of divisional regions arranged in a vertical direction and controllable independently in regard to whether or not light should be blocked; a polarizing element has a plurality of divisional regions arranged in vertical direction and controllable independently in regard to whether the polarization direction should be set to that for the left eye or the right eye; and a control circuit controls the optical shutter and the polarizing element in synchronism with a writing position in the liquid crystal panel. | 02-12-2009 |
| 20090309959 | STEREOSCOPIC IMAGE PROJECTOR AND ADAPTER FOR STEREOSCOPIC IMAGE PROJECTOR - A stereoscopic image projector includes: an image generator configured to generate three left-eye wavelength-specific images and three right-eye wavelength-specific images having different wavelengths by modulating three light beams having the different wavelengths in spatial modulators; an image combiner configured to combine the three left-eye wavelength-specific images into a single left-eye combined image and the three right-eye wavelength-specific images into a single right-eye combined image; a relay lens configured to receive the left-eye and right-eye combined images and focus real images of the left-eye and right-eye combined images that are separated from each other; a light guide configured to separately guide the real images of the left-eye and right-eye combined images; a left-eye image projection lens and a right-eye image projection lens respectively configured to project the real images of the left-eye and right-eye combined images guided through the light guide on a screen so that left-eye and right-eye images are focused. | 12-17-2009 |
| 20100039526 | Signal processing apparatus and method, and program - Signals are provided which allow colors in a wider color range than predetermined standards, which can be handled by apparatus according to such predetermined standards. A primary color converter converts first color signals having primary color points in a wider color range than the primary color points according to BT.709 into second color signals based on the primary colors according to BT.709. A photoelectric transducer converts the second color signals into third color signals according to photoelectric transducer characteristics defined in a numerical range wider than a range from 0 to 1.0 of color signals corresponding to a luminance signal and color difference signals according to BT.709. A color signal converter converts the third color signals into a luminance signal and color difference signals. A corrector incorporated in the color signal converter corrects the color difference signals into color difference signals. | 02-18-2010 |

| 20100182571 | Projection image display apparatus and projection optical system - A projection image display apparatus includes: a light source; an illumination optical system that uniformly irradiates a surface of an image modulation element serving as a primary image surface with a light beam emitted from the light source; and a projection optical system that enlarges and projects image information on the primary image surface modulated by the image modulation element onto a screen serving as a secondary image surface, and that includes a first optical system that forms an intermediate image from the image information, a single-image second optical system that enlarges and projects the intermediate image to display a single image on the screen, a plural-image second optical system that enlarges and projects the intermediate image to display plural images on the screen, and an optical path switching mechanism that selectively guides a light beam from the first optical system to the single-image or plural-image second optical system. | 07-22-2010 |
| 20100195006 | PROJECTION DISPLAY APPARATUS - A projection display apparatus includes a light source configured to emit light, at least one reflective liquid crystal device configured to generate an image by modulating a polarization of the light emitted from the light source and reflecting the light, an imaging lens configured to form a real image of the image generated by the reflective liquid crystal device, a quarter-wave plate disposed between the reflective liquid crystal device and the imaging lens, an image splitter configured to include at least one reflecting plane and spatially split the real image into at least two split real images by reflecting the real image on the reflecting plane, at least two projection lenses configured to form the split real images again on a screen, and a phase difference corrector configured to correct a phase difference between a p-polarized light and an s-polarized light generated by the reflecting plane. | 08-05-2010 |
