Title: Timing signal generation circuit
Inventor: WATANABE KAZUHIRO
IPC: H04N19/80
Filed: 1990-05-25
Abstract: PURPOSE:To prevent occurrence of a malfunction of a timing signal by allowing a guard time signal generating circuit to decide an allowable range of fluctuation of an initialize signal. CONSTITUTION:A differentiating circuit 105 outputs an initialize signal 108 to a gate circuit 109 in response to a change in a horizontal synchronizing signal 103. The circuit 109 outputs a signal 108 to a counter circuit 107 as a reset signal 112 only when a guard time signal 111 outputted from a guard time signal generating circuit 110 is true. A reset pulse generating circuit 113 compares a count outputted from the circuit 107 with a set value and when they are coincident, the reset signal 114 is outputted to the circuit 107. The circuit 107 is reset by the reset signals 112, 114. Thus, the occurrence of malfunction of the timing signal is prevented by selecting and inputting plural reset signals to the counter circuit.
