Claims

[Scope of utility model registration request]

(1) An eyepiece (on the ophthalmologist's side) and photographing lens provided opposite to the optical path of the fundus image objective lens (on the patient's side), a light source for illumination, a flash light source for photographing, an illumination aperture device to which a filter can be attached, and It consists of a fixation target device, a semiconductor image sensor optically connected to the eyepiece/photographing lens side, a videotape recorder and a cathode ray tube electrically connected to the semiconductor image sensor, and further includes the above-mentioned components as necessary. 1. A fundus camera image processing device comprising a personal computer connected to a semiconductor image sensor or a videotape recorder, a graphics display, a printer, a floppy disk, etc.

(2) An electrical conversion device such as a semiconductor image sensor or an image pickup plate that electrically converts an optical image is installed in the optical part of the eyepiece (on the ophthalmologist's side) lens used in the observation system of the fundus camera configuration. A fundus camera image processing device according to claim 1, characterized in that the fundus camera image processing device is connected to each other.

(3) A semiconductor image pickup device (or image pickup plate) that electrically converts an optical image is connected to the optical path of the observation system of the fundus camera configuration or the eyepiece/taking lens used for photography. The electrical image signals captured by the elements are transmitted to i-video tape recorders, cathode ray tubes, personal computer graphic displays, printers,
A fundus camera image processing device according to claim 1, which is configured to be capable of image processing using a floppy disk or the like.
