摘要： A parallel scanning circuit outputs a parallel scanning signal for making forward and backward scanning lines parallel. A vertical correlation detection circuit detects a portion where the change in luminance in the vertical direction exceeds a predetermined value on the basis of a luminance signal, and outputs a movement control signal representing the distance of movement on the screen of the scanning line. A retrace period reversion circuit reverses the lime axis of the movement control signal in a retrace period. A clamping circuit clamps the movement control signal to a predetermined DC voltage at the timing of horizontal synchronizing signal. A synthesizing circuit synthesizes the parallel scanning signal and the movement control signal, and feeds a synthesized signal as a vertical velocity modulation signal to a vertical velocity modulation coil.

摘要： A video signal of an interlaced scanning system having 525 scanning lines and a vertical scanning frequency of 60 Hz is converted to a video signal having 1050 scanning lines and a vertical scanning frequency of 120 Hz, for displaying an image by bidirectional scanning. A vertical synchronizing signal is subjected to offset processing by a ¼ horizontal scanning period when an odd field is started, thereby keeping interlaced relation between odd and even fields. The vertical synchronizing signal is subjected to offset processing by a ½ horizontal scanning period every frame, so that the scanning direction for each scanning line is reversed every frame.

摘要： A video signal converter converts a video signal to a required form. The required form of the signal is the display format for displaying the signal. The input signal is converted to a digital signal and stored in a memory using the output of a first clock pulse generator synchronized to the horizontal synchronizing signal of the input signal. The digital signal is read out from the memory using the output of a second clock pulse generator synchronized to the vertical synchronizing signal of the input signal from a position specified by the controller. The output digital signal is then reconverted to an analog signal.
