Abstract:
A video signal processing apparatus, comprising:means for determining whether an input signal is a progressive scanning first video signal or an interlace scanning second video signal and generating a determination signal corresponding to the determined result;first converting means for converting said first video signal into an interlace scanning third video signal when said first video signal has been input;means for outputting a fourth video signal, said fourth video signal corresponding to said second video signal when said determination signal represents that said second video signal has been input and corresponding to said third video signal when said determination signal represents that said first video signal has been input;second converting means for converting said fourth video signal into a progressive scanning signal corresponding to motion information of said fourth video signal when said fourth video signal corresponds to said second video signal;third converting means for converting said fourth video signal into a progressive scanning signal corresponding to said first converting means when said fourth video signal corresponds to said third video signal; andmeans for selecting an output signal of said second converting means and outputting a fifth video signal when said determination signal represents that said second video signal has been input and for selecting an output signal of said third converting means and outputting a fifth video signal when said determination signal represents that said first video signal has been input.
