Patent ID: 7300154

Claim:
An ophthalmologic image taking apparatus comprising: an illumination optical system that includes an observation illumination light source and an image taking illumination light source for illuminating an eye to be examined; an image pickup unit for receiving a reflection light as an image of the eye to be examined from the eye to be examined; an amplifying unit for amplifying an output signal from the image pickup unit; a gain control unit for controlling a gain of the amplifying unit, the gain control unit having a first gain setting mode for changing the gain in accordance with the output signal from the image pickup unit and a second gain setting mode for setting the gain to a fixed gain; a control unit for obtaining an output signal amplified by the amplifying unit as the image of the eye to be examined, the control unit having a first operational mode in which the output signal from the amplifying unit controlled in the first gain setting mode is continuously obtained and recorded on a record unit, and a second operational mode in which the output signal from the amplifying unit controlled in the second gain setting mode is obtained in synchronized with an emission of the image taking illumination light source and is recorded on the record unit as a still image; and a mode switch for switching between the first operational mode and the second operational mode of the image capturing unit, wherein the control unit determines a recording waiting time from switching to the first operation mode to starting of moving image recording.
