Abstract

PURPOSE: To improve stability with influence of external noise eliminated, by digitally compensating time delay caused by a camera cable.
CONSTITUTION: In addition to horizontal and vertical synchronizing signals, synchronizing-signal generating part 4 generates clock CL for counting the delay time of a signal owing to cable between camera control part 1 and camera head 2. Singal P3 equivalent to the delay time by cable allows gate circudit 7 to gate clock CL and counter 8 to count it. The number of clocks having passed through gate circuit 7 is subtracted from the value set initially to counter 8 and the remainder is stored in latch circuit 9. In counter 10, subtraction from the latched value is done sequentially and when it becofmes zero, pulse P6 is outputted. This output leads the reference signal in terms of phase and is supplied to camera head 2 by way of leading-phase pulse generating part 5.
