Abstract
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.
