  • Publication number: 20110085085
    Abstract: A visual processing device, display device, visual processing method, program, and integrated circuit that change a strength of visual processing of an image in real-time. A spatial processing portion (2) creates an unsharp signal US from an input signal IS. A target level setting portion (4) sets a predetermined target level value L for setting a range according to which the strength of the visual processing is adjusted. An effect adjustment portion (5) creates a synthesized signal MUS by synthesizing the predetermined target level value L and the unsharp signal US in accordance with an effect adjustment signal MOD that has been set externally. A visual processing portion (3) outputs an output signal OS in accordance with the input signal IS and the synthesized signal MUS, making it possible to change the strength of the visual processing.

  • Patent number: 7860339
    Abstract: The invention is a visual processing device having a hardware configuration that does not depend on achieving visual processing, wherein the visual processing device includes a spatial processing portion and a visual processing portion. The spatial processing portion performs predetermined processing with respect to an input signal IS that has been received as input, and outputs the result as an unsharp signal US. The visual processing portion outputs an output signal OS, which is the input signal IS after the visual processing, based on a two-dimensional LUT that lists a relationship between the input signal IS, which that has been received as an input, the unsharp signal US, and the output signal OS.

  • Publication number: 20100172348
    Abstract: The present invention provides a network relay apparatus capable of assuring the prevention of occurrence of order reversion of packets within flows and shifting a packet distribution destination according to load information. The network relay apparatus includes: a packet distribution processor for distributing input packets to thereby achieve load dispersion of packet processing; a statistical information collector for regularly collecting load conditions of respective packet processors; and a distribution information holder for retaining information for specifying the packet distribution destinations upon distribution of the packets. Information about the load conditions of the respective packet processors are compiled and distributed to the packet processor smallest in load. Timing provided to change the packet distribution destination is assumed to be given when a processing waiting queue does not include a packet corresponding to its flow.
