Title:
IMAGING DEVICE FOR MEASUREMENT OF SPECTACLE WEARING PARAMETER, AND IMAGING PROGRAM FOR MEASUREMENT OF SPECTACLE WEARING PARAMETER
Document Type and Number:
Japanese Patent JP2015210506
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To enable easier positioning between a device and a subject.SOLUTION: The imaging device for measurement of a spectacle wearing parameter is used for imaging a face of a subject wearing a spectacle frame, the imaging device comprising: an imaging optical system having first imaging means for imaging the face of the subject including the spectacle frame from a front direction or from downward and second imaging means for imaging the face of the subject including the spectacle frame from a direction different from the front direction; and positioning means capable of positioning between the imaging optical system and the subject on the basis of an image of the face of the subject imaged by the second imaging means such that a deflection angle of the spectacle frame in a horizontal direction can be adjusted.
