    摘要： A waveform analysis unit divides digital data of a video signal stored in a Y memory and a C memory into small blocks, and conducts average value separation and normalization on each of the small blocks. A 1/f fluctuation measuring unit first derives a self-correlation function for each of the normalized small blocks, folds back the self-correlation function to the negative side, and conducts correction processing for making an average self-correlation function over a predetermined section equal to 0. Subsequently, the 1/f fluctuation measuring unit conducts Fourier transform on the corrected self-correlation function, derives a power spectrum, and conducts straight line approximation of the power spectrum. The 1/f fluctuation measuring unit then derives a fluctuation value of the power spectrum from the approximate straight line. An abnormality determination unit makes a determination on video quality abnormality on the basis of the variance value of the small block, coefficients of the approximate straight line derived by the straight line approximation, and the fluctuation value.

    摘要： This invention provides a mode determination system for maximizing the coding efficiency by minimizing the amount of generated encoded information. An intra-frame picture signal X of 16 pels 16 lines is divided into four sub-blocks of 8 pels.times.8 lines by a DCT block dividing unit. A DCT block dispersion calculation unit calculates the dispersions of the four sub-blocks, and a nonlinear function transform unit transforms the dispersions to values for estimating amounts of generated encoded information. An adder unit adds together the four values for estimating amounts of generated encoded information and outputs the sum. On the other hand, a motion compensated predictive difference Y of 16 pels.times.16 lines undergoes a processing similar to said intra-frame picture signal X by a DCT block dividing unit, a DCT block dispersion calculation unit, a nonlinear function transform unit and an adder unit, and a value for estimating an amount of generated encoded information for the motion compensated predictive difference Y is outputted from the adder unit. An comparator unit outputs a signal for selecting a mode according to which of the two values for estimating amounts of generated encoded information is smaller.

    摘要： It is sought to provide a motion vector post-processor, which can improve motion vectors of blocks containing boundaries of objects in different movements to provide as visually satisfactory interpolated field quality as possible. Motion vectors generated in a motion estimator are stored in a memory, and their magnitudes are calculated in a magnitude calculator. Magnitude data is fed to an order statistics filter. The filter detects the serial number of a motion vector (for instance third motion vector) less than a magnitude at the center among a plurality of (for instance nine) input motion vectors and outputs corresponding serial number data to the memory. The memory outputs the vector corresponding to the input serial number data to a field interpolator. According to the invention, it is possible to provide a motion vector of an area containing small movement as motion vector of a block containing mixed movements.
