Patent ID: 7325926

Claim:
An ophthalmologic photographic device comprising: (1) electronic image pickup means for photographing the eye to be examined; (2) amplifying means for amplifying signals from said image pickup means; (3) amplification rate varying means for varying the amplification rate of said amplifying means; and (4) amplification mode switching means for switching an amplifying mode of amplifying the signals in the amplifying means, between a fixed amplification mode wherein the signals are amplified using a fixed amplification rate and an automatic amplification mode wherein the signals are amplified using a varied amplification rate which is automatically varied by the amplification rate varying means, wherein: in a case that after the amplification mode switching means switches the amplifying mode from a firstly set automatic amplification mode to the fixed amplification mode, the amplifying mode is switched from the thus set fixed amplification mode to a secondly set automatic amplification mode, wherein the amplification rate varying means varies the amplification rate at the time of starting the secondly set automatic amplification mode on the basis of the amplification rate in the firstly set automatic amplification mode.
