a display screen unit that displays the third image prepared by the information processing unit; an operation unit that specifies a measurement reference point of the spectacle wearing parameter on the third image displayed on the display screen unit; and a measurement computation section that calculates the spectacle wearing parameter by using data of the specified measurement reference point. ## Claims ### Claim 1 A spectacle wearing parameter measurement device used in measurement of a spectacle wearing parameter of a subject who is to wear a spectacle frame, the spectacle wearing parameter measurement device comprising: an information processing unit that acquires each of a first image as a face image of the subject in a spectacle-frame wearing state and a second image as a face image in a spectacle-frame non-wearing state and prepares a third image obtained by associating the first image and the second image; a display screen unit that displays the third image prepared by the information processing unit; an operation unit that specifies a measurement reference point of the spectacle wearing parameter on the third image displayed on the display screen unit; and a computation unit that calculates the spectacle wearing parameter by using data of the specified measurement reference point. ### Claim 2 (depends on 1) The spectacle wearing parameter measurement device according to claim 1, wherein the third image is a synthetic image obtained by synthesizing the first image in the spectacle-frame wearing state and the second image in the spectacle-frame non-wearing state and includes at least a measurement position. ### Claim 3 (depends on 2) The spectacle wearing parameter measurement device according to claim 2, wherein the synthetic image is a synthetic image of a partial region of the first image in the spectacle-frame wearing state and a corresponding region of the second image in the spectacle-frame non-wearing state. ### Claim 4 (depends on 3) The spectacle wearing parameter measurement device according to claim 3, wherein the partial region is a region including a rim part of the spectacle frame worn by the subject on the first image obtained by imaging a lateral side of the face of the subject, and the corresponding region is a region not including an eyeball corneal part of the subject on the second image obtained by imaging a lateral side of the face of the subject. ### Claim 5 A spectacle wearing parameter measurement program that causes a computer provided with a display screen unit and an operation unit and used in measurement of a spectacle wearing parameter of a subject who is to wear a spectacle frame to function as: an image processing section that prepares a third image obtained by associating a first image as a face image of the subject in a spectacle-frame wearing state and a second image as a face image in a spectacle-frame non-wearing state; a display control section that displays the third image by the display screen unit, the third image prepared by the image processing section; an operation control section that causes the operation unit to specify a measurement reference point of the spectacle wearing parameter on the third image displayed on the display screen unit; and a measurement computation section that calculates the spectacle wearing parameter by using data of the specified measurement reference point. ### Claim 6 A position specifying method for specifying, when a spectacle wearing parameter about a subject is to be measured by using a face image of the subject in a wearing state of a spectacle frame, a measurement reference point on the face image required for the measurement, the position specifying method comprising: acquiring each of a first image as the face image of the subject in a spectacle-frame wearing state and a second image as the face image in a spectacle-frame non-wearing state; when the measurement reference point is to be specified, preparing and displaying a third image obtained by associating the first image in the spectacle-frame wearing state and the second image in the spectacle-frame non-wearing state; and specifying the measurement reference point of the spectacle wearing parameter on the third image.
