  • Patent number: 9363502
    Abstract: Provided are an apparatus for synchronizing a stereocamera, a stereocamera, and a method of synchronizing a stereocamera. The apparatus for synchronizing a stereocamera includes a synchronization error calculating unit configured to calculate a synchronization error from output signals of first and second image sensors, and a pulse adjusting unit configured to adjust a pulse of a synchronization signal of at least one of the first and second image sensors using the calculated error. In addition, the stereocamera and the method of synchronizing the same are provided.

  • Patent number: 8422560
    Abstract: A method and apparatus for encoding/decoding a media signal. The method of decoding a media signal includes extracting first table index information from a header. The first table index information indicates M (M<N) tables substantially referred to by frames from among N tables which can be referred to for performing an operation performed by the frames, wherein N and M are natural numbers. Second table index information is then extracted from each frame. The second table index information indicates tables referred to by each frame from among M tables. The tables, which are referred to by the frames, are then identified by using the first and second table index information and the frames are decoded by referring to identified tables.

  • Patent number: 7006711
    Abstract: The present invention relates to storing information including electronic ink. Ink is stored in a data structure that includes a mapping of the ink's coordinates from one space to another. The responsibility of transforming the ink into desired coordinates occurs after the capture of the ink and at least based on the mapping in the data structure.

  • Patent number: 6965702
    Abstract: A method of sharpening a digital image having image pixels according to its noise content, includes the steps of providing an image sharpener having a variable parameter of sharpening; generating a noisy pixel belief map corresponding spatially to the image pixels having belief values indicating the likelihood that the modulation about respective pixels are due to system noise; and using the noisy pixel belief map to vary the parameter of the image sharpener.

  • Patent number: 6915022
    Abstract: The present invention discloses an image preprocessing method capable of increasing the accuracy of face detection by enhancing the contrast between dark pixels and their surrounding bright pixels, and increasing the brightness difference between dark pixels and bright pixels. Even in insufficient and non-uniform lighting conditions, the eye-analogue segments of a human face are obvious; so as to make a subsequent algorithm using eye-analogue segments for detecting human faces and producing more accurate results.

  • Patent number: 6891977
    Abstract: A method of sharpening a digital image having image pixels according to its material content, includes the steps of: generating a subject matter belief map corresponding spatially to the image pixels, having belief values indicating the likelihood that respective image pixels are representative of a particular subject matter, generating a noisy pixel belief map corresponding spatially to the image pixels having belief values indicating the likelihood that the modulation about respective pixels are due to system noise; generating gain map from the subject matter belief map and the noisy pixel belief map having values that indicate the degree of sharpening to be applied to the image pixels; and using the gain map to sharpen the image.
