  • Publication number: 20110157213
    Abstract: According to one embodiment, a first extraction unit extracts a first group of pixels having a specific hue from an input image. A second extraction unit extracts a second group of pixels having large distance from a reference axis on a plane defined by a chroma axis and a luminance axis from the first group. A first transform unit executes a plurality of color-transform processing to the second group and obtains a plurality of third groups of pixels as the second group transformed by each color-transform processing. A reliability calculation unit calculates a reliability of each third group. The reliability is larger when pixels of the third group are more located in shape of a straight line on the plane. A selection unit selects a color-transform processing by which the third group has the largest reliability from the plurality of color-transform processing. A second transform unit executes the color-transform processing to the input image to obtain an output image.

  • Patent number: 7502799
    Abstract: In the case where metadata refers to relevant content on a network, since the relevant content on the network can not be necessarily permanently held, it is desirable that a time limit for making reference can be set. Besides, in order to provide relevant content which can be referred to only in a limited period for promoting sales, or in order to provide relevant content which can be referred to only in a limited period such as, for example, Christmas Day every year for raising the entertainingness of the metadata, it is desirable that a reference time limit of the relevant content can be set. Then, in order to set an effective time limit of an access unit, a flag to specify the effective time limit and the effective time limit are described in each access unit.
