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.
