Patent number: 9077983Abstract: 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.Type: GrantFiled: January 20, 2012Date of Patent: July 7, 2015Assignee: Optoma CorporationInventors: Yau Wing Chung, Yi-Chun Lu

Patent number: 8928807Abstract: 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.Type: GrantFiled: March 18, 2008Date of Patent: January 6, 2015Assignee: Optoma CorporationInventors: Tzung-I Lin, Yi-Chun Lu, Chih-Yang Liu
