<p>PROBLEM TO BE SOLVED: To allow suitable display of an image of a subject.SOLUTION: A spectacle wearing parameter measurement instrument includes a front imaging optical system which captures a front image of a subject wearing a spectacle frame and can vary an imaging distance from the subject, and a lateral imaging optical system for capturing a lateral image of the subject wearing the spectacle frame and measures a spectacle wearing parameter on the basis of the front image and the lateral image. The spectacle wearing parameter measurement instrument further includes display control means for displaying, on a display unit, the front image captured by the front imaging optical system and the lateral image captured by the lateral imaging optical system and magnification correction means for correcting the magnification of at least either one of the front image and the lateral image in accordance with variation of the imaging distance so that the front image and the lateral image displayed on the display unit are equally reduced independently of the variation of the imaging distance.</p> |
