  • Patent number: 8106976
    Abstract: The present invention corrects the insufficient peripheral light amount due to the lens shading and correcting the non-uniformity of light amount at the periphery due to a distortion resulting from a precision of the lens or a poor mounting precision of the lens. A peripheral light amount correction circuit is structured by an image synchronization signal generation circuit, a coordinate conversion circuit and a luminance value correction computing circuit. An integrated value of luminance values is calculated at the coordinate conversion circuit to extract light amount information. Coordinate values to be input to the luminance value correction computing circuit are generated based on an integrated/averaged value of the light amount information. In the luminance value correction computing circuit, peripheral light amount correction functions are converted based on the input coordinate values from the coordinate conversion circuit to perform appropriate correction on the input image.

  • Patent number: 8102592
    Abstract: Interferometric modulators include a movable mirror that is actuated by voltage applied to a plurality of electrodes relative to at least one other electrode, to define a cavity relative to a partially reflective mirror formed by a top plate. The depth of the cavity determines a bandwidth of light that is modulated by internal reflections within the cavity and which interferes with light that is reflected from a partially reflective mirror on the top plate, producing a desired reflected color of light for the modulator. Variations in manufacturing and material characteristics can cause the movable mirror to tilt relative to the partially reflective mirror, which degrades the modulation accuracy. To compensate, different voltages can be applied to the plurality of electrodes. The voltage can be determined at time of manufacture and stored in non-volatile memory, for use when the modulator is actuated during use.

  • Patent number: 8098294
    Abstract: An image processing apparatus capable of suppressing color fringing in a color image further effectively by image processing. A determination unit determines a region in which signal levels for a color plane in a color image produced by photoelectric conversion of an optical image of a subject exhibit a monotonic increase or a monotonic decrease, as a color fringing region in which color fringing occurs. An estimation unit estimates an intensity of the color fringing in the color fringing region determined by the determination unit. A removal unit deducts an estimate value of the intensity of the color fringing estimated by the estimation unit from the intensity of the color fringing in the color fringing region.

  • Patent number: 8075136
    Abstract: An apparatus that can measure images of at least a portion of an eye and record data sets indicative of a neurological condition. A method interrelates an image and a data set to provide an interpretive result. The apparatus and method thereby provide guidance as to the presence of a medical condition in a patient. The apparatus and method can be used in an iterative measurement process, in which the apparatus attempts to discern normal health from a state of health that is not normal health. If the interpretive result is consistent with normal health, the process terminates, information is recorded, and an optional report is given. If the interpretive result is not consistent with normal health, the apparatus and method attempts to distinguish which condition is consistent with the data and images used, and can iterate with additional measurements and information to attempt to provide a useful interpretive result.

  • Patent number: 8072672
    Abstract: The thermally switched reflective optical shutter is a self-regulating “switchable mirror” device that reflects up to 100% of incident radiant energy above a threshold temperature, and reflects up to 50% of incident radiant energy below a threshold temperature. Control over the flow of radiant energy occurs independently of the thermal conductivity or insulating value of the device, and may or may not preserve the image and color properties of incoming visible light. The device can be used as a construction material to efficiently regulate the internal temperature and illumination of buildings, vehicles, and other structures without the need for an external power supply or operator signals. The device has unique aesthetic optical properties that are not found in traditional windows, skylights, stained glass, light fixtures, glass blocks, bricks, or walls.
