Abstract

There is an provided eyeglass fitting parameter measurement device including: a display control unit that displays a front image of an examinee wearing an eyeglass frame and a lateral image of the examinee wearing the eyeglass frame on a display part; and a position information detection unit that detects position information for determining the positions of the examinee's eyes or the eyeglass frame based on one of the front image and the lateral image. The display control unit provides a correspondence indication corresponding to the position information detected by the position information detection unit in a display area for the other of the front image and the lateral image based on the position information.

First claim

What is claimed is:

1. An eyeglass fitting parameter measurement device comprising:
a display control by a processor that displays a front image of an examinee wearing an eyeglass frame and a lateral image of the examinee wearing the eyeglass frame on a display part;
a position information detection by a processor that detects position information for determining the positions of the examinee's eyes or the eyeglass frame based on a first image which is one of the front image and the lateral image; and
an instruction acceptance device that accepts an instruction from an examiner, wherein
the display control processor displays, by overlapping with examinee's eyes and the eyeglass frame in the first image, a first target corresponding to the position information and by overlapping with examinee's eyes and the eyeglass frame in a second image which is another one of the front image and the lateral image, a second target at a same height as the first target,
the position information detection processor detects the position information based on the instruction from the instruction acceptance device for moving one of the first target and the second target with respect to the examinee's eyes and the eyeglass frame displayed on the display part, and
the display control processor moves another one of the first target and the second target with respect to the examinee's eyes and the eyeglass frame displayed on the display part in synchronization with a result of detection of the position information of the one of the first target and the second target moved based on the instruction.

2. The eyeglass fitting parameter measurement device according to claim 1 , wherein
a second position information detection by a processor that, based on the instruction from the instruction acceptance device regarding the display area for the second image in which the position information is displayed, detects position information for determining the positions of the examinee's eyes or the eyeglass frame in the second image.

3. The eyeglass fitting parameter measurement device according to claim 1 , wherein
the first image is the front image, and
the second image is the lateral image.

4. The eyeglass fitting parameter measurement device according to claim 1 , wherein the display control processor displays the front image, a right lateral image of the examinee, and a left lateral image of the examinee on the display part at the same time.

5. The eyeglass fitting parameter measurement device according to claim 1 , wherein the first target and the second target are connected together in the display part.

6. The eyeglass fitting parameter measurement device according to claim 1 , wherein
the lateral image includes a right lateral image and a left lateral image,
the first image is the front image,
the second image is one of the right lateral image and the left lateral image,
the display control processor displays the front image, the right lateral image and the left lateral image on the display part, and displays, by overlapping with examinee's eyes and the eyeglass frame in a third image which is another one of the right lateral image and the left lateral image, a third target at a same height as the first target.

7. A non-transitory storage medium storing an eyeglass fitting parameter measurement program executed by a processor of an eyeglass fitting parameter measurement device for measuring eyeglass fitting parameters for an examinee by analyzing a front image of the examinee wearing an eyeglass frame and a lateral image of the examinee wearing the eyeglass frame to cause the eyeglass fitting parameter measurement device to perform:
a display control displaying the front image and the lateral image on a display part;
detecting position information for determining the positions of the examinee's eyes or the eyeglass frame based on a first image which is one of the front image and the lateral image; and
accepting an instruction from an examiner, wherein
the display control displays, by overlapping with examinee's eyes and the eyeglass frame in the first image, a first target corresponding to the position information and by overlapping with examinee's eyes and the eyeglass frame in a second image which is another one of the front image and the lateral image, a second target at a same height as the first target,
detecting the position information is based on the instruction from the examiner for moving one of the first target and the second target with respect to the examinee's eyes and the eyeglass frame displayed on the display part, and
the display control moves another one of the first target and the second target with respect to the examinee's eyes and the eyeglass frame displayed on the display part in synchronization with a result of detection of the position information of the one of the first target and the second target moved based on the instruction.

8. A non-transitory storage medium storing an eyeglass fitting parameter measurement program executed by a processor of an eyeglass fitting parameter measurement device for measuring eyeglass fitting parameters to cause the eyeglass fitting parameter measurement device to perform:
a display control displaying on a display part a front image taken by a front imaging optical system configured to take the front image of an examinee wearing an eyeglass frame and a lateral image of the examinee wearing the eyeglass frame taken by a lateral imaging optical system configured to take the lateral image, the front imaging optical system being capable of changing an imaging distance to the examinee;
detecting position information for determining the positions of the examinee's eyes or the eyeglass frame based on a first image which is one of the front image and the lateral image;
accepting an instruction from an examiner; and
correcting the magnification rate of at least one of the front image and the lateral image according to a change in the imaging distance such that the reduction scales of the front image and the lateral image displayed on the display part become equal regardless of the change in the imaging distance, wherein
the display control displays, by overlapping with examinee's eyes and the eyeglass frame in the first image, a first target corresponding to the position information and by overlapping with examinee's eyes and the eyeglass frame in a second image which is another one of the front image and the lateral image, a second target at a same height as the first target,
detecting the position information is based on the instruction from the examiner for moving one of the first target and the second target with respect to the examinee's eyes and the eyeglass frame displayed on the display part, and
the display control moves another one of the first target and the second target with respect to the examinee's eyes and the eyeglass frame displayed on the display part in synchronization with a result of detection of the position information of the one of the first target and the second target moved based on the instruction.

9. An eyeglass fitting parameter measurement device executing the eyeglass fitting parameter measurement program according to claim 8 .
