  • Patent number: 8508585
    Abstract: A three-dimensional video reproduction apparatus includes: a video decoder unit which generates a right-eye video signal and a left-eye video signal; a graphics decoder unit which generates a right-eye graphics signal and a left-eye graphics signal; a synthesizing unit which synthesizes the right-eye video signal and the right-eye graphics signal and synthesizes the left-eye video signal and the left-eye graphics signal, to generate a right-eye output signal and a left-eye output signal; and an output unit which reproduces the three-dimensional video by alternately outputting the right-eye and left-eye output signals. When two adjacent pixels in the right-eye or left-eye output signal are represented by a common chrominance signal, and are generated respectively using a video signal and a graphics signal, the synthesizing unit generates the common chrominance signal such that a synthesis ratio of the video signal and the graphics signal is biased in favor of one of these.

  • Publication number: 20120128327
    Abstract: A video reproducing device capable of synthesizing a first image being a stereo image and a second image and outputting a synthesized, including: an acquiring unit operable to acquire a first image and a second image to be synthesized in one frame; and a synthesizing unit operable to generate the synthesized image by synchronously synthesizing the first image and the second image acquired by the acquiring unit, and output the synthesized image, wherein, if the acquiring unit fails to acquire the second image to be synthesized in the one frame when the synthesizing unit generates the synthesized image, the synthesizing unit synthesizes a second image which is to be synthesized with a first image of a frame other than the one frame with the first image to be synthesized in the one frame.

  • Patent number: 6925038
    Abstract: The present invention provides an optical disc apparatus which solves a problem that the tracking control takes off when an objective lens is displaced in the tracking direction due to its weight. In this optical disc apparatus, a spot position detector 108 generates a spot position signal which indicates a position of a light spot on a light receiving element 105, and supplies the signal to a traverse loop filter 111 and a spot position loop filter 109. A controller 115 supplies an output from the spot position loop filter 109 to a tracking actuator 104, before supplying an output from the traverse loop filter 111 to a traverse motor 113, previously moves the light spot near the center of the light receiving element 105, and starts the traverse control in a state where a value of the spot position signal at starting of the traverse control is reduced.

  • Patent number: 5629919
    Abstract: In an optical head, a light emitting element emits an optical beam, and the beam is condensed by a condensing element onto an information recording medium. A first plate beam-splitting element has a splitting ratio of P polarization to S polarization, and it splits at least a part of the beam reflected by the information recording medium along a direction different from that of a direction returning to the light emitting element. A second plate beam-splitting element is provided in parallel to the first plate beam-splitting element, and it splits the beam split by the first plate beam-splitting element into at least two beams having polarization planes perpendicular to each other. The two beams are detected by a pair of photosensors.
