Abstract
The apparatus radiates light onto an eye to be examined and picks up an image of the eye, which is irradiated with light. And then the apparatus compares image information obtained from the image pickup with a threshold determined in advance for the image information so as to store the image information larger than the threshold. The apparatus calculates a measured value of the eye to be examined on the basis of the stored image information.
