ABSTRACT:
A synchronization detector of a video signal processor includes a line buffer, a parameter extraction unit and synchronization detection unit. The line buffer sequentially stores a digital video signal corresponding to an input analog video signal, line by line of the input analog video signal. The parameter extraction unit continuously extracts horizontal synchronization parameters from the digital video signal stored line by line and continuously extracts vertical synchronization parameters from a portion of the digital video signal stored line by line. The synchronization detection unit generates horizontal and vertical synchronization signals of the input analog video signal using time information related to local minimum values of the horizontal synchronization parameters and time information related to local minimum values of the vertical synchronization parameters.
