  • Publication number: 20140063576
    Abstract: An image processing apparatus of the present invention acquires a photographed image of an object on which indicators have been arranged, detects the indicators from the photographed image with use of a comparison reference image for pattern matching prepared in advance, and instructs to perform predetermined processing based on the detected indicators. The indicators each have a pattern where influence of geometrical image distortion generated corresponding to a photographing distance or a photographing angle with respect to the object is restrained by a central portion of the photographed image, and the comparison reference image is a partial image corresponding to a central portion of the indicator. The indicators are detected from the photographed image by comparing the comparison reference image with the acquired photographed image.

  • Patent number: 8558956
    Abstract: An image display system comprises red, green and blue laser light sources, a spatial light modulator that modulates the laser light of different colors in a time sharing manner and a controller that controls the operation of the laser light sources and the spatial light modulator. The green and red laser light sources are lit in this order in each frame. The green color is diminished due to the response delay of the spatial light modulator, but the green laser light produced by the green laser light source has a relatively large color phase shift from the standard green color so that the shortage of green color cancels the color phase shift of the generated green color so that the color phase shift of the displayed intermediate color can be minimized.

  • Publication number: 20120327379
    Abstract: An image display apparatus including a laser light source apparatus with a semiconductor laser as a light source increases the heat releasing ability of the laser light source apparatus in the image display apparatus. In order to accomplish this, a heat sink is provided to a green color laser light source apparatus, which generates green color light by wavelength conversion from infrared light and, therefore, produces a greater amount of heat than the other laser light source apparatuses. In addition, an air flow blocking cover is mounted on the surface of the holder, covering the temperature sensor, to prevent distribution to the temperature sensor of cooling air from the cooling fan disposed adjacent to the red color laser light source apparatus. It is thus possible to comply with laser safety standards.

  • Patent number: 8023743
    Abstract: When a user instructs photographing by operating an operating unit, an image captured by an image sensor is stored as a photographed image in a memory. When a mode for performing color fading correction is set, the CPU instructs an image processing device to extract, from the photographed image, areas in which there are photographic print images which are supposed to bring about color fading. The image processing device generates a binary image by detecting edges of the photographed image, erases edges contacting an outermost edge of the photographed image, and extracts the areas based on the binary image from which some of the edges are erased.
