ABSTRACT:
A fundus camera for performing fluorescent image pickup is provided. A timer is started when a fluorescent agent is infused into a body, and a mode of an amplifying ratio control part is set to AGC. AGC is then checked, and fluorescent illuminance curves of respective eyes to be examined are calculated, if the AGC is operating. A fluorescent illuminance value at a fundus is calculated from a gain value on the AGC and a corresponding time which are stored in an amplifying ratio memory, thereby determining a proper exposure value. When the AGC is not operating, the fluorescent illuminance value is calculated from the calculated illuminance curves of the respective eyes to be examined and an output of a timer, thereby determining a proper exposure value. When an image pickup switch is depressed while observing an image, input from the image pickup switch is detected.
