  • Patent number: 9928598
    Abstract: A depth measurement apparatus that calculates depth information of an object based on a first color image and a second color image. A depth calculator calculates depth information of a target pixel in a color plane, using the two color images. An evaluator calculates, for each color plane, an evaluation value to indicate a confidence coefficient of the depth information in the target pixel. The depth calculator (i) determines, based on the evaluation value, a color plane from which the depth information of the target pixel is calculated, (ii) calculates a correlation value in one color plane between the two color images, to calculate the depth information from the correlation value using a conversion table or a conversion formula that is different for each color plane, and (iii) calculates the depth information of the target pixel using a color plane of which a correlation value is a threshold or less.

  • Patent number: 9930332
    Abstract: Reference prediction mode values, also referred to as most probable modes, usable for encoding or decoding of a prediction mode related to a current coding unit, are derived. First and second reference prediction mode values are derived (S402) from respective prediction modes of at least two neighboring coding units of the current coding unit. The first and second reference prediction modes are different. A third reference prediction mode value is derived (S403) from the first and second reference prediction mode values. The third reference prediction mode is different from each of said first and second reference prediction mode values. By deriving three MPMs instead of two for comparison with the prediction mode of the current coding block the coding efficiency is improved. This is due to the increase in the probability that the prediction mode of the current coding block corresponds to one of the derived most probable modes.
