  • Patent number: 8073091
    Abstract: A phase determination unit in a signal processing circuit generates sampling clocks with different phases in a clock generator and sequentially provides them to an analog-to-digital convertor. Then, the phase determination unit obtains differences between each adjacent two signal levels in each sampled digital signal by use of the sampling clocks, and monitors a polarity change in the differences, extracts a more inappropriate phase for use in sampling from phases of the sampling clocks on the basis of the absolute values of the differences where the polarity change is detected, and determines an antiphase of the extracted phase as a phase of the sampling clock to be provided to the analog-to-digital convertor.

  • Publication number: 20100026902
    Abstract: A video signal processing apparatus generates first to third correlation values based on five sequential video line signals C(n?2) to C(n+2) that include two kinds of color-difference signals transmitted line sequentially. The first correlation value indicates degree of similarity between C(n+1) and C(n?1), the second correlation value indicates degree of similarity between C(n+2) and C(n), and the third correlation value indicates degree of similarity between C(n) and C(n?2). When the degree of similarity between C(n+1) and C(n?1) is evaluated to be smaller than a predetermined level based on the first correlation value, the apparatus determines a mixing ratio of C(n+1) and C(n?1) according to relative magnitude of the third correlation value with respect to the second correlation value. The apparatus outputs a mixed signal obtained by mixing the signals C(n+1) and C(n?1) according to the mixing ratio and the video signal C(n) as two simultaneous color-difference signals.
