A jitter canceling apparatus is provided for canceling jitter in a video signal. For processing a video signal, using as a reference an internal synchronization signal and an external synchronization signal different from the internal synchronization signal in the jitter canceling apparatus, an external synchronization signal generator generates the external synchronization signal from an external reference signal. A jitter detector detects time difference jitter, which is jitter in a time difference between the internal and external synchronization signals. The external synchronization signal generator controls the external synchronization signal generating operation in response to the detected time difference jitter to reduce the time difference jitter.
