A technique preferable for ophthalmic image taking having an image taking
optical system for imaging an image on an image sensing element at
different imaging magnifications is disclosed which includes an image
sensing element for converting the eye-to-be-examined fundus image into
digital image data; an image taking optical system for imaging the
eye-to-be-examined fundus image on the image sensing element at different
image magnifications; fundus illumination means for illuminating fundus
at a light intensity interlocking with the imaging magnifications; and
region selection means for selecting a specific region including a fundus
image from the image data in accordance with the imaging magnifications.
Moreover, it is characterized to lower the light intensity of the fundus
illumination means by interlocking with reduction of the imaging
magnifications and contract the specific region by interlocking with
reduction of the imaging magnifications.
