Abstract

PURPOSE:To improve picture quality substantially by increasing the number of scanning lines of a picture to be displayed and disposing an intermediate video signal, calculated on estimation by video signals on scanning lines before and after each increased scanning line, on the scanning line. CONSTITUTION:A video signal is separated by a synchronous separating circuit 2 and the video signal is encoded by an A/D converter 3 to be stored in a memory 4. Between signals on two scanning lines, a video signal considered to be present on a new scanning line is calculated and inserted to obtain an output composite video signal. This signal is converted into an analog signal by a D/A converter 6. As a synchronizing signal, a composite synchronizing signal is generated by adding a synchronizing signal for interpolating scanning at a synchronizing signal synthesizing circuit 9 in timing as required between input synchronizing signals by a timing circuit 8, and the generated signal is sent from an output terminal 10 to a deflecting circuit.
