  • Patent number: 9077983
    Abstract: A decoder, a projecting system, and a method for processing an image thereof are provided. The decoder is adapted to the projecting system having a projecting module and a shutter glass. The decoder includes a decoding circuit and an indicating unit. The projecting module outputs a frame turning control signal to the shutter glass. The decoding circuit receives and decodes a three-dimensional (3D) video signal to produce a first image data and a second image data to the projecting module. The indicating unit is coupled to the decoding circuit and correspondingly produces an indicating signal when the decoding circuit outputs one of the first image data and the second image data.

  • Patent number: 8928807
    Abstract: Playback control methods and systems are provided. At least one picture is obtained. The picture corresponds to a frame, and the picture includes a first region and a second region adjacent to the first region. It is determined whether at least one pixel in the first region has a predefined color, and whether at least one pixel in the second region has the predefined color. When the pixel in the first region has the predefined color and the pixel in the second region does not have the predefined color, the first region is removed, and the second region is enlarged to cover an original position of the first region. The enlarged second region is then played back via an anamorphic lens.

  • Patent number: 8238601
    Abstract: A system and method for removing digital watermarks from a watermarked image of an electronic device are provided. The method decomposes the watermarked image to a plurality of Eigen-images, assigns an identifier to each of the Eigen-images in sequence, and identifies an identifier range of the Eigen-images to be removed from the watermarked image. The method further selects Eigen-images having watermarked information from the identifier range, deletes the Eigen-images having watermarked information from the Eigen-images within the identifier range, and integrates the remainder Eigen-images of the identifier range to form a composite image. Additionally, the method determines whether the composite image is distorted, and stores the composite image into a storage device of the electronic device if the composite image is not distorted.

    Abstract: Methods and devices for catalyzing reactions, e.g., in a metal-air electrochemical cell, are disclosed. In some instances, a porous positive electrode of the metal-air electrochemical cell includes a metal to catalyze a reaction at the electrode (e.g., oxidation of one or more metal-oxide species). The metal can be disposed as nanoparticles, and/or be combined with a second metal. Other aspects are directed to devices and methods that can generally promote a chemical reaction (e.g., an oxidation/reduction reaction) such as the formation of platinum containing nanoparticles that can be used to catalyze electrochemical reactions.
