PROBLEM TO BE SOLVED: To determine the opacity of a translucent body such as the crystalline lens of an eye to be examined, etc. SOLUTION: The contrast C, the minimum value MN and a half value width W concerning the minimum value and a peak are obtained with respect to the luminance distribution of image information for the portion of one line which is obtained by an imaging device in a step S1. In a step S2, the minimum value MN is evaluated by an optional threshold S(MN) and, then, a judgment processing is completed in the case of No. In a step S3, the contrast C is evaluated by an optional threshold S(C) and, then, the judgment processing is ended in the case of No. In a step S4, the half value width W is evaluated by an optional threshold S(W) and the judgment processing is ended in the case of No. When Yes is obtained in the whole steps, it is judged that the eye to be examined E has opacity in the translucent body and it is displayed in a step S5. |
