A frequency distribution monitor unit partitions, into a plurality of classes, a size of a vertical component of a motion vector, and detects a frequency of the number of occurrences at which the vertical component occurs in each of the classes. In a case where the vertical component of the motion vector exceeds a predetermined threshold value in predetermined specific classes, the offset control unit creates offset signals which shift read addresses in the vertical direction in delay units. A selection control unit controls to shift, in the vertical direction, pixel data selected by delay selection units.

Video signal processing apparatus and method

A motion vector detecting apparatus includes a correlation detecting unit, a repetitive object detecting unit and a motion vector detecting unit. The correlation detecting unit detects correlations among plural pieces of pixel data in plural directions. The repetitive object detecting unit detects whether or not concerned pixel data in which a motion vector is to be detected is located in a repetitive object. The motion vector detecting unit decreases a difference value in a direction coincident with a direction of motion vector having detected at a past time when the concerned pixel data is located in the repetitive object and detects a motion vector.

Motion vector detecting apparatus and motion vector detecting method

A repetitive object detecting device includes data-retention and difference-calculation units, an adding unit, a horizontal direction accumulating unit and a small and large comparing unit. Each data-retention and difference-calculation unit carries out, with respect to a plurality of lines, a process for setting as reference pixel data pixel data located at an end of a plurality of pieces of pixel data, and calculating a difference between the reference pixel data and pixel data separated from the reference pixel data by k pixels (2&#x2266;k&#x2266;maximum number) to obtain difference data by each separated pixel number k. The adding unit adds the difference data in the plurality of lines by each separated pixel number k. The horizontal direction accumulating unit accumulates the added data by each separated pixel number k in a horizontal direction. The small and large comparing unit carries out a small and large comparison with respect to the horizontal accumulated value by each separated pixel number k to decide whether or not the reference pixel data is pixel data which is located in a repetitive object including a certain repetitive pattern.
