Title:
SPECTACLE WEARING PARAMETER MEASURING APPARATUS, SPECTACLE WEARING PARAMETER MEASUREMENT PROGRAM AND IMAGE ACQUISITION METHOD
Document Type and Number:
Japanese Patent JP2015064254
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a spectacle wearing parameter measuring apparatus capable of spectacle wearing parameter measurement with higher accuracy by enabling the clear acquisition of an image of an area around the eyes of a subject being an imaging object even though the performance of an autofocus mechanism is low because the apparatus body is all-purpose and portable.SOLUTION: The spectacle wearing parameter measuring apparatus includes an imaging camera part for imaging a face vicinity of a subject wearing a spectacle frame together with a measurement auxiliary tool arranged in the face vicinity of the subject, a display screen part for functioning as an imaging viewfinder for image-displaying an imaging object, and an information processing part for using an acquired imaging result to calculate a spectacle wearing parameter about the subject. The imaging camera part focuses on an imaging object existing at a position different from a display position of the measurement auxiliary tool in the display screen part or an area which has almost the same distance from the imaging camera part as a distance to the imaging object after detecting and focusing on the measurement auxiliary tool, and acquires the imaging result with the focusing as an opportunity.
