ABSTRACT:
A microcomputer (11) supplies pulse width data (12) which is responsive to the frequency of a synchronizing signal (SS). A flip-flop (14) is set on the trailing edge of the synchronizing signal (SS). A counter (15) counts clock pulses (18) in a high-level period of output from the flip-flop (14), and supplies the result of measurement (19) to a comparator (13). The comparator (13) compares the pulse width data (12) with the result of measurement (19), and supplies a reset signal (20) to the flip-flop (14) upon a judgement on coincidence. The flip-flop (14) is reset in response to the reset signal (20). Thus, the pulse width of a clamp pulse (CS) outputted from the flip-flop (14) can be controlled on the basis of the pulse width data (12).
