Abstract:
A flash and photograph synchronizer for a fundus camera having an actuator, a resettable flash unit accommodating a flash sequence in a flash interval after actuation of the actuator and requiring power interruption thereto for resetting, and a digital camera system including an auxiliary power supply and a shutter system having a mechanical shutter movable to a fully open position in a mechanical transit time consistent with said flash interval for capturing a image at said digital camera system, said synchronizer comprising:power supply means;first circuit means including first mechanical switching means for operatively connecting said auxiliary power supply with said shutter system upon operation of the actuator moving said mechanical shutter to said fully open position; andsecond circuit means including second mechanical switching means connected between said power supply means and said flash unit for actuating said flash unit upon operation of said actuator to initiate the flash sequence during said flash interval, said second mechanical switching means effecting power interruption to said flash unit subsequent to said operation of the actuator thereby permitting the resetting thereof.
