<P>PROBLEM TO BE SOLVED: To precisely measure a glasses wearing parameter even in a case that the face of a subject to be examined is oscillated in a right and left direction. <P>SOLUTION: The glasses wearing parameter measuring instrument has a front image inputting means 133 for taking in the front image of the face of the subject to be examined, a side surface image inputting means 135 for taking in the side surface image of the face of the subject by a side surface photographing means 63 and a measuring operating means 139 for measuring and operating the glasses wearing parameter on the basis of the front image and the side surface image. The side surface image inputting means has a face oscillation angle measuring means 138 for measuring the oscillation angle of the face by the front part of a glasses frame and a side face photographing direction altering means 137 for altering the photographing direction of the side surface photographing means to the just lateral direction of the front part of the glasses frame to photograph the side surface image, and the measuring operating means is constituted so that a glasses wearing distance is operated on the basis of the side surface image, the distance between left and right eye pupils is measured by using the front surface image and the distance between the left and right eye pupils measured based on the face oscillation angle and the glasses wearing distance is corrected to the value in the case that the face oscillation angle is zero. <P>COPYRIGHT: (C)2008,JPO&INPIT |
