摘要:
Ophthalmic photographing an image of an eye to be examined comprises: frame memory for memorizing the image data of the photographed eye, light detecting device for detecting an amount of the light emitted from a light source for photographing, correcting device for correcting a density of the image data memorized in the frame memory by comparing the amount of the light detected by the light detecting device with predetermined amount of reference light. Therefore the ophthalmic photographing apparatus can display the image having a constant density, even though the amount of the light emitted from the light source for photographing changes.
