  • Publication number: 20160146640
    Abstract: An optical encoder includes a light emitting module, a positioning device and a light separating structure. The light emitting module emits a light beam illuminating an illumination area of the positioning device. The positioning device includes light penetrating areas arranged in a dislocation manner. The light penetrating areas sequentially move into the illumination area. The light separating structure is disposed in the path of the light beam. The positioning device is disposed between the light emitting module and the light separating structure. When part of the light beam penetrates one of these light penetrating areas and is transmitted to the light separating structure, the light separating structure transmits the light to a sensing area and forms at least one first positioning optical pattern. The distance between two first positioning optical patterns formed by two adjacent light penetrating areas is greater than the pitch between the two adjacent light penetrating areas.

  • Patent number: 8331707
    Abstract: An electrical-device-implemented image coding method includes: a raw block is obtained from an image. There are a max pixel value and a min pixel value among the raw pixel values of the image. A first difference sum, which is sum of differences between the raw pixel values and the max pixel value respectively, are calculated. A second difference sum, which is sum of differences between the raw pixel values and the min pixel value respectively, are calculated. If the first difference sum is not smaller than the second difference sum, each of the residue values is calculated by subtracting the min pixel value from the corresponding raw pixel value. Otherwise, each of the residue values is calculated by subtracting the corresponding raw pixel value from the max pixel value. Each of the residue values is encoded into a compressed codeword. A bit stream is generated according to the compressed codewords.
