Abstract
An apparatus for converting an input video signal to a modified video signal comprises a memory for storing data corresponding to the input video signal, an address signal generating device for reading data from the memory and an interpolating filter for interpolating the data read from the memory to obtain a modified video signal. The data are stored and read from the memory using a clock having a predetermined frequency. However, since the number of addresses being read in one horizontal display varies with the conversion rate of video signals, the length of one horizontal display of the modified video signal is different from that of the input video signal.
