ABSTRACT:
A synchronization processing circuit separates synchronizing signals from an input video signal, provides the synchronizing signals to a detection circuit, and further provides the input video signal that has no synchronizing signal to a scaler circuit. The detection circuit detects the horizontal synchronization frequency, the vertical synchronization frequency, the synchronization polarity, the synchronization type (Sep, CS, or GSync), the scan type, the image line number, the synchronization type (TriSync), and the vertical synchronization width from the synchronizing signals. A CPU determines the type of input video signal based on the detection results of the detection circuit. Based on the determination results, the CPU sets the signal processing for the input video signal in the synchronization processing circuit and in the scaler circuit.
