ABSTRACT:
An analog image signal is converted into a digital image signal which is in turn subjected to various types of processing procedures. The resulting digital image data is added to synchronizing data having the same range of data change as that of the image data to generate image data containing the synchronizing data. This image data is then converted into an analog image signal. An offset signal is applied to the analog image signal to adjust the voltage level of the synchronizing signal for obtaining an image signal containing a correct synchronizing signal.
