摘要： An image memory 10 delays an input video signal by one frame period and a motion vector detection circuit 20 detects a motion vector between frames of video signals. A pull-down detection circuit 22 determines whether or not a video signal is pull-down converted and a motion vector conversion circuit 21 generates control signals to control delay amounts in delay circuits 30 to 32 based on the motion vector and the determination result of pull-down conversion. The delay circuit compensates for the motion of a video signal based on the control signal to generate a motion-compensated video signal and time axis emphasis circuits 40, 41 emphasize the motion-compensated video signal in a time axis direction by another video signal to generate an emphasized video signal. A time series conversion memory 50 converts the frame rate of the emphasized video signal into a higher frame rate and outputs the emphasized video signal.

摘要： 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 ≦ k ≦ 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 obj ect including a certain repetitive pattern.

摘要： A Gaussian filter 2 having a first cutoff frequency extracts a low frequency component signal of a video signal. A subtracter 3 extracts a high frequency component signal by subtracting the low frequency component signal from the video signal. A low pass filter 5 having a second cutoff frequency higher than the first cutoff frequency extracts a lower high frequency component signal, which is a low-frequency-side signal of the high frequency component signal. A multiplier 6 generates a corrected component signal by multiplying the lower high frequency component signal by a predetermined gain G1. An adder 7 adds the corrected component signal to the video signal.
