IPC: A61B3/14
Filed: 1988-09-07
Abstract: PURPOSE:To reduce the probability of the failure in photographing an eyeground, by photographing the eyeground image plural times while changing the exposure of the image pick-up element before the pupil of the eye being inspected starts shrink age after it receives visible light. CONSTITUTION:An area type CCD 70 which works as an image pick-up element, photographs an eyeground image from the eyeground 2a caused by visible light which has been radiated through a holed mirror 12 and an object lens 11 at the time of the luminescence of a stroboscope tube 61. An eye being inspected 2 under the condition of the pupil being spread, shrinks its pupil in 0.2-0.3 seconds after receiving the visible light, so a plurality of light emitting control signals are transmitted within a response time before the shrinkage of the pupil occurs. The stroboscopic tube 61 is caused to emit light every first field of each image frame by means of the output of this light emitting control signal, and at the same time, control is made so that the light emitting time may become longer every light emission, and the light receiving amount of the CCD 70 becomes more every light emission, in turn. Accordingly, the probability of a failure at the time of the eyeground image being photographed by means of the image pick-up element, becomes lower, and at the same time, plural eyeground images can be photographed under different exposure conditions.
