  • Patent number: 7465053
    Abstract: A lens array wheel 4 receives light irradiated in a direction parallel to its rotation axis, to cyclically deflect the light. On each of liquid crystal display panels 7R, 7G, and 7B, the light is circularly scrolled, the effect of substantial intermittent illumination is produced, and hold blurring is reduced. A panel driver 15 starts to feed a pixel-driving signal in the succeeding frame to a pixel existing at a position, through which an illuminating area passes, on each of the liquid crystal display panels 7R, 7G, and 7B.

  • Publication number: 20080136926
    Abstract: An amplification signal of a difference signal between a sensor signal and an offset signal to be variably set is converted into a digital signal. The sensor signal is in accordance with shake of an imaging device and outputted from a sensor. The first digital signal is obtained while a conversion ratio between the difference signal and the digital signal is set to a first conversion ratio. The second digital signal is obtained while the conversion ratio is set to a second conversion ratio. In relation to a certain difference signal, the value of the second digital signal is smaller than that of the first signal. The offset signal is updated based on the second digital signal. The shake information is generated based on the first digital signal.

  • Patent number: 7161614
    Abstract: There is provided parallax correction means for correcting a parallax for each area calculated by parallax calculation means in accordance with the magnitude of a motion vector for the area detected by motion vector detection means in order to prevent the three-dimensional effect of a conversion video from greatly differing depending on an input video when the MTD method and the CID method are simultaneously used. When a depth estimate is converted into a parallax, the depth estimate is subjected to distance scale conversion in order to suppress the distortion of the conversion image, to find a tentative target phase for each parallax calculation area, and a dynamic range in which a phase difference between the parallax calculation areas is within a distortion allowable range is searched for and is subjected to distance scale conversion, to find a tentative target phase, which operations are repeated.
