ABSTRACT:
A video signal processing device is designed to input selectively a first video signal or a sub-sampled second video signal. These inputs are input to a common filter. The output of the filter is output after being sub-sampled, when the first video signal is being input, and without being sub-sampled, when the second video signal is being input. The output level of the filter is changed over between when the first video signal is being output and when the second video signal is being output.
