    Abstract: An image display device, a viewing device, and a method for operating the same are provided. The method includes pairing a first viewing device with the image display device; displaying a first image corresponding to a first channel during a first period in synchronization with the first viewing device so that the first image can be viewed with the use of the first viewing device; and displaying a second image during a second period subsequent to the first period in synchronization with the first viewing device so that the second image cannot be viewed with the use of the first viewing device. This allow users to concurrently view different images using different viewing devices on a single image display device.

    Abstract: A phase error detection unit measures a phase error between an external synchronization signal and a spectacles control signal that is fed back, more specifically, a discrepancy between vertical synchronization timing and shutter opening/closing timing, that is, jitter. A timing correction unit corrects the shutter opening/closing timing, using the measured jitter. Specifically, a parameter indicating the corrected shutter opening/closing timing is written to a storage unit. The storage unit stores a parameter used to generate the spectacles control signal, for example, the parameter indicating the shutter opening/closing timing. A signal generation unit generates the spectacles control signal, using the parameter stored in the storage unit. A frequency divider divides the frequency of the spectacles control signal by n.

  • Patent number: 8675042
    Abstract: A distance to an object is measured for each of a series of left images, and the count of a distance range including the calculated distance increases. A distance range with the highest frequency of appearance is specified from the counter information of a distance table counter, and a left image in which the distance included in the specified distance range is measured is selected. The adjustment amount of the parallax amount adjusted for the selected left image and a corresponding right image is determined to be the adjustment amount of the parallax amount of a panorama image. A series of left images is combined to generate a panorama image and a series of right images is combined to generate a panorama image. A panorama image displayed in stereoscopic view is generated based on the determined adjustment amount of the parallax amount.

    Abstract: A plurality of parallax images which are time-divisionally displayed are processed so that correct parallax can be displayed even during motion picture display. When a plurality of image streams of input signals to the video signal processing unit 120 are captured or generated with the same timing, interpolation processing for generating an interpolated image in terms of time is performed on at least one of the plurality of image streams, and the change of the apparent parallax is suppressed. More specifically, interpolation processing in terms of time is performed, so that a time difference of a time at which interpolation images of a plurality of image streams are generated is the same as a time difference of operation for separating the corresponding parallax images.
