摘要： Input analog image signals are converted to digital image signals and applied to a demodulation circuit and a synchronous circuit. In the demodulation circuit, the digital image signals are demodulated and then compressed by a compression circuit. In the synchronous circuit, the digital image signals are synchronously processed so as to output horizontal pulses in accordance with a horizontal synchronizing signal contained in the digital image signals and so as to output phase difference information denoting a timing difference between the output of a horizontal pulse and an interpolated crossing of the horizontal synchronizing signal across a synchronizing threshold. A boundary at an image portion and a mask portion of an output image signal is corrected so that the boundary is substantially free of jitter using the horizontal pulses and the phase difference information output by the synchronous circuit. In this manner, a smooth boundary is obtained at the image portion and mask portion of the final compressed image.

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： The invention relates to a video signal memory equipment comprising a FIFO memory for storing video data of video signals, and a control unit for controlling writing and reading in the FIFO memory, wherein the control unit receives a horizontal synchronizing signal of video signal in video data writing action, writes a specified number of video data from the beginning of video data of brightness signals of the horizontal scanning period sequentially into the FIFO memory, and reads out the specified number of video data upon every input of horizontal synchronizing signal, in video data reading action, in the written sequence as video data of that horizontal scanning period, thereby storing and producing the video data of video signals, whereby video data of each horizontal scanning period of video signals are continuously written into the FIFO memory by every specified number of pieces from the beginning, and are read out by every specified number of pieces upon every input of horizontal synchronizing signal, and hence the video data of video signals can be read out by dividing in every horizontal scanning period, and therefore the address generating device for dividing the data in every horizontal scanning period is not needed in this video signal memory equipment.
