Abstract
In a synchronizing signal selection circuit, in response to the input of a vertical synchronizing signal extracted from a composite synchronizing signal, a control signal is generated. The control signal is in a predetermined state during a period which begins when a first predetermined time period has elapsed after the input of the vertical synchronizing signal, and which terminates when a second predetermined time period has elapsed after the input of the vertical synchronizing signal. The composite synchronizing signal is output when the control signal is in the predetermined state, and a horizontal synchronizing signal separated the composite synchronizing signal is output when the control signal is in a state other than the predetermined state.
