<Overview>
Embodiments of the present disclosure will be described based on the drawings. In the present disclosure, the horizontal direction (left and right direction) of the eyeglasses mapping information acquisition device is described as an X direction, the vertical direction (vertical direction) as a Y direction, and the depth direction (front and rear direction) as a Z direction. Further, in the present disclosure, the description will be made by attaching the code L to those indicating the left use and the reference R to the one indicating the right use. In the present disclosure, “parallel” includes a completely parallel state and a substantially parallel state. The items classified by <> below may be used independently or in association.

  The application of the present disclosure is not limited to the device described in the present embodiment. For example, solution control software (program) performing the functions of the following embodiments is supplied to a system or apparatus via a network or various storage media, and the control apparatus (for example, CPU etc.) of the system or apparatus It is also possible to read out and execute.

  For example, the eyeglasses mapping information acquisition apparatus (for example, the eyeglasses mapping information acquisition apparatus 1) includes a lens measurement unit (for example, measurement optical system 10). Also, for example, the eyeglasses mapping information acquiring apparatus includes mapping image acquiring means (for example, the control unit 60). Also, for example, the eyeglasses mapping information acquiring apparatus includes a frame image acquiring unit (for example, the control unit 60). Also, for example, the eyeglasses mapping information acquisition device includes a processing unit (for example, the control unit 60). Also, for example, the eyeglasses mapping information acquisition apparatus includes a control unit (for example, the control unit 60).

<Lens measurement means>
For example, the lens measurement means measures the lens characteristic of each part of the lens (for example, the lens LE). For example, the lens characteristic may be the spherical power S of the lens, cylindrical power C, astigmatic axis angle A, prism amount Δ or the like. Also, for example, the lens characteristics may be represented as a two-dimensional distribution. In this case, the two-dimensional distribution may indicate the entire area of the lens. In this case, the two-dimensional distribution may indicate a partial area of the lens. In addition, as a partial region of the lens, a distance portion, a near portion, and the like of the lens can be mentioned.

  For example, the lens measurement unit may include at least a light receiving element (for example, the light receiving element 16) and a light source (for example, the light source 11). For example, in this case, the lens measurement unit may include a lens (for example, at least one of the condenser lens 12 and the imaging lens 15). Also, for example, the lens measurement means may include an index plate (for example, the index plate 13). Also, for example, the lens measuring means may comprise a screen (e.g. screen 14).

<Mapping image acquisition means>
For example, the mapping image acquisition unit acquires a mapping image (for example, the mapping image 95) indicating the lens characteristics of each part of the lens. For example, the mapping image may be an image showing regions where the lens characteristics of each part of the lens are equal. In this case, the mapping image acquisition unit may acquire the mapping image by forming an equal power line (for example, equal power line 96) connecting measurement positions having the same lens characteristics. Also, in this case, the mapping image acquisition unit may create a graphic representing an equal frequency line and acquire a mapping image graphically represented by color-dividing an area having the same lens characteristic.

  For example, the mapping image acquisition unit may be configured to acquire the mapping image acquired by the eyeglasses mapping information acquisition apparatus. For example, in this case, the mapping image acquisition unit may acquire a mapping image based on the lens characteristic measured by the lens measurement unit. For example, the mapping image acquisition unit may be configured to acquire a mapping image acquired by another device. In this case, the mapping image acquisition unit may acquire the mapping image by receiving the mapping image from another device. In this case, the mapping image acquisition unit may acquire the mapping image by reading the mapping image stored in the external memory from another device. Of course, the mapping image acquisition means may acquire a mapping image by acquiring a lens characteristic measured by another device and creating a mapping image using this lens characteristic.

  Note that, for example, the mapping image acquisition unit may be configured to acquire a mapping image by capturing a corresponding mapping image from a plurality of mapping images stored in advance in a database. In this case, mapping images acquired by measuring lens characteristics in advance may be stored in the database. Also, in this case, the database may store mapping images based on lens design data used when manufacturing the lens.

  For example, the plurality of mapping images stored in the database may be mapping images indicating lens characteristics. Also, for example, the plurality of mapping images stored in the database may be mapping images in which the eye point position of the wearer is indicated together with the lens characteristics. Also, for example, the plurality of mapping images stored in the database may be a mapping image in which the geometrical center position of the lens is indicated together with the lens characteristics.

<Frame image acquisition means>
For example, the frame image acquisition means acquires a frame image (for example, a frame image 90) of a frame of glasses. For example, the frame image may be an image including at least a frame image (for example, a frame image Fp) of glasses. In this case, the frame image of the glasses may include one of the left frame image of the glasses and the right frame image of the glasses. Of course, the frame image of the glasses may include both the left frame image of the glasses and the right frame image of the glasses.

  For example, the frame image acquisition unit may detect a frame image of the glasses by image processing the image captured by the light receiving element to acquire a frame image. For example, as image processing, it may be possible to detect a frame image of glasses. That is, for example, the frame image acquisition unit may be configured to perform edge detection on an image including a frame image of glasses. Also, for example, the frame image acquisition means may be configured to perform difference processing between an image including a frame image of glasses and an image not including a frame image of glasses.

  For example, the frame image acquisition unit may be configured to acquire a frame image acquired by the eyeglasses mapping information acquisition apparatus. For example, in this case, the frame image acquisition unit may acquire a frame image from the light receiving image (for example, the light receiving image 65) captured by the light receiving element. For example, the frame image acquisition unit may be configured to acquire a frame image acquired by another device. In this case, the frame image acquisition unit may acquire a frame image by receiving a frame image from another device. In this case, the frame image acquisition unit may acquire a frame image by reading a frame image stored in an external memory from another device. Of course, the frame image acquisition means may acquire a frame image by acquiring a frame detection result detected by another device and creating a frame image based on the frame detection result.

  Note that, for example, the frame image acquisition unit may be configured to acquire a frame image by capturing a corresponding frame image from a plurality of frame images stored in advance in a database. In this case, frame images acquired by measuring frame shapes of the glasses in advance may be accumulated in the database. Further, in this case, the database may store a frame image created by graphic based on the result of measuring the frame shape of the glasses. Also, in this case, a frame image based on frame design data used when manufacturing a frame may be accumulated in the database.

  For example, the plurality of frame images stored in the database may be frame images showing frame shapes of glasses. Also, for example, the plurality of frame images stored in the database may be frame images in which the eye point position of the wearer is indicated together with the frame shape. Also, for example, the plurality of frame images stored in the database may be a frame image in which the boxing center of the frame is shown together with the frame shape.

  For example, the frame image may be information indicating the frame shape of the glasses. For example, the frame shape of the glasses may be the shape of the outer edge of the rim of the glasses. Also, for example, the frame shape of the glasses may be the shape of the inner edge of the rim of the glasses. Also, for example, the frame shape of the glasses may be the shape of the groove bottom of the rim of the glasses. For example, the frame image may be information indicating the shape of the lens framed in the glasses. For example, the lens shape may be a lens shape. Also, for example, the shape of the lens may be an edge line of the demo lens. That is, the frame image may be information related to the shape of the frame in the glasses or the shape of the lens.

<Processing means>
For example, the processing means associates the mapping image with the frame image. Also, for example, the processing unit acquires an eyeglass image (for example, an eyeglass image 100) in which the mapping image and the frame image are associated with each other. For example, this makes it possible to grasp how the lens characteristic is positioned with respect to the frame.

  For example, the processing means may be configured to associate these images so that the positional relationship between the mapping image and the frame image can be grasped. For example, in this case, as a method of associating the mapping image with the frame image, there is a configuration in which the position of the frame image of the glasses in the frame image is shown in the mapping image. Also, for example, in this case, as a method of associating the mapping image with the frame image, there is a configuration in which the mapping image and the frame image are superimposed.

  For example, the processing means can acquire a glasses image in which the mapping image and the frame image are superimposed by superimposing and associating the mapping image and the frame image. This makes it possible to determine whether the positional relationship between the eyeglass frame and the lens is good. Also, this makes it possible to easily determine the position of the lens characteristic with respect to the frame. In particular, in a progressive lens, it can be easily determined whether its distance and near parts are within the frame.

  Note that, for example, the processing unit may acquire a plurality of glasses images. For example, in this case, the processing means may be configured to acquire at least two or more glasses images.

<Control means>
For example, the control means comparesably outputs a plurality of eyeglass images in which at least one of the lens characteristic, the frame, and the positional relationship between the mapping image and the frame image is different. Thereby, a good combination of the eyeglass frame and the lens can be selected. In addition, it is possible to easily compare changes in the degree of visibility due to differences in the glasses. Also, for example, the control means outputs a plurality of glasses images in parallel. As a result, it is possible to easily consider a good combination of the eyeglass frame and the lens from a plurality of eyeglass images. In addition, it becomes easy to grasp how the lens characteristics, the degree of visibility, and the like have changed from the plurality of glasses images. In addition, it is easy to explain to the wearer the differences in the lens characteristics and the degree of visibility.

  For example, the control means outputs the plurality of eyeglass images on the display means so as to output them comparably. For example, in this case, the display means may be a display means provided in the eyeglasses mapping information acquisition device. Also, for example, the display means may be a display means of an apparatus different from the eyeglasses mapping information acquisition apparatus. Also, for example, the display means may be a display means of a portable terminal (for example, a tablet terminal or the like). For example, this allows eyeglasses images to be easily compared. Therefore, the operator can select a good combination of the eyeglass frame and the lens. In addition, it is easy to understand the differences in lens characteristics and appearance.

  For example, the control means may be made comparable by displaying a plurality of glasses images in parallel on the display means. Further, for example, the control means may display one eyeglass image on the display means and switch the display means to make it possible to compare a plurality of eyeglass images. That is, for example, the control unit may be able to compare a plurality of glasses images by performing at least one of parallel display of glasses images and switching of display units.

  Note that, for example, the control unit may be configured to output comparisons by storing a plurality of glasses images in an external memory. In addition, for example, the control unit may be configured to output the plurality of glasses images so as to be comparable by transferring them to another device. Also, for example, the control unit may be configured to output the images so as to be comparable by printing a plurality of glasses images. For example, in this case, a plurality of glasses images may be arranged and printed on one sheet of paper.

  For example, the eyeglasses mapping information acquisition apparatus in the present embodiment may include eye point acquisition means (for example, the control unit 60) for acquiring eye point data of the wearer. For example, in this case, the processing means superimposes a marker mark (for example, the marker mark 120) based on eye point data on at least one spectacle image in a plurality of spectacle images. Of course, the processing means may superimpose the marker mark on all the glasses images in the plurality of glasses images.

  For example, when the eyeglasses mapping information acquiring apparatus includes eye point acquiring means, the control means outputs a plurality of eyeglass images comparably to each other, and at least one marker mark superimposed on the plurality of eyeglass images is Output along with multiple glasses images. By this, it can be grasped where the eye point position etc. of the wearer is located with respect to the frame of the glasses, and it can be easily judged whether the combination of the spectacle frame and the lens is good for the wearer.

  Also, for example, the eyeglasses mapping information acquisition apparatus in the present embodiment may have a configuration for acquiring the position of the hidden mark of the lens. For example, in this case, the processing means may superimpose the hidden mark on at least one eyeglass image in the plurality of eyeglass images. Of course, the processing means may superimpose the marker mark on all the glasses images in the plurality of glasses images.

  Note that, for example, the position of the hidden mark may be acquired by an eyeglass mapping information acquisition apparatus separately provided with an optical system for detecting the hidden mark. Also, for example, the position of the hidden mark may be acquired by the eyeglasses mapping information acquisition apparatus which combines the optical system for detecting the hidden mark and the measurement optical system. Of course, for example, the position of the hidden mark may be obtained by another device.

<Example>
Hereinafter, the eyeglasses mapping information acquisition apparatus in a present Example is demonstrated. FIG. 1 is an external view of the eyeglasses mapping information acquisition apparatus 1. For example, the eyeglasses mapping information acquisition apparatus 1 includes a housing 2, a display (monitor) 3, an operation button 4, and the like. For example, the housing 2 includes the storage unit 5 therein. The details of the storage unit 5 will be described later.

  For example, the display 3 is configured by any one of an LCD (Liquid Crystal Display), an organic EL (Electro Luminescence) display, a plasma display, and the like. For example, the display 3 may be mounted on the eyeglasses mapping information acquisition apparatus 1 or may be connected to the eyeglasses mapping information acquisition apparatus 1. Of course, the eyeglasses mapping information acquisition apparatus 1 in the present embodiment may be configured to use a plurality of displays in combination.

  For example, the display 3 displays lens information of the lens LE framed in the glasses F. For example, the lens information is the lens characteristics of the lens LE (for example, spherical power S, cylindrical power C, astigmatic axis angle A, prism amount Δ, etc.), the mapping image 95 (see FIG. 16) etc. . Although the details of the mapping image 95 will be described later, the mapping image 95 may be an image in which the lens characteristics are represented by the equal power frequency line 96, or an area where the lens characteristics are equal (that is, equal power frequency lines and equal powers It may be an image graphically represented by color coding or the like) in the region between the lines.

  For example, the display 3 is a touch panel. That is, in the present embodiment, the display 3 functions as an operation unit (controller). For example, a signal corresponding to the operation instruction input from the display 3 is output to the control unit 60 described later. The display 3 may not be of the touch panel type, and the display 3 and the operation unit may be provided separately. For example, in the case where the display 3 and the operation unit are separately provided, at least one of a mouse, a joystick, a keyboard, a button, a portable terminal and the like can be used as the operation unit.

  For example, the operation button 4 is displayed on the screen of the display 3. For example, the operation button 4 is used when the glasses mapping information acquisition apparatus 1 inputs a signal for performing various processes (for example, start of measurement of a lens characteristic). That is, the operator can operate the operation button 4 by touching the screen of the display 3.

  FIG. 2 is a schematic diagram of the inside of the storage unit 5. For example, the storage unit 5 includes a glasses support unit 20, a drive unit 30, a measurement unit 7, and the like. For example, the glasses support unit 20 supports the glasses F. For example, the drive unit 30 moves the eyeglass support unit 20 in the front-rear direction (Z direction), the left-right direction (X direction), and the vertical direction (Y direction) with respect to the measurement unit 7. For example, the measurement unit 7 includes a measurement optical system 10 described later. Also, for example, the measurement unit 7 includes an abutment pin 6 that abuts on the rear surface of the lens LE. For example, the contact pin 6 is fixed to the upper surface of the index plate 13 provided in the measurement optical system 10.

  For example, the contact pin 6 is configured of three. For example, the contact pins 6 are arranged so as to be equidistant and equiangular to the optical axis L1 of the measurement optical system 10. That is, the contact pin 6 starts from the base point with each contact pin 6 starting from the point at which the optical axis L1 passes through the index plate 13 (the point where the reference index 71 (see FIG. 4) is located in this embodiment). It is arranged so that the distance to it becomes equal. The contact pins 6 are arranged such that the angles formed by the two straight lines connecting the base point and the contact pins 6 are equal (that is, 120 degrees). The contact pin 6 may be in any number as long as it can contact the rear surface of the lens LE. The contact pins 6 may be disposed at different distances from the optical axis L1 of the measurement optical system 10, or may be disposed at different angles.

<Glasses support unit>
For example, the glasses support unit 20 supports the glasses F at at least two or more places. For example, the eyeglass support unit 20 includes a front support 21, a rear support 22, and a base 23. For example, the front support 21 and the rear support 22 are fixed to the base 23.

  For example, the front support 21 supports the position of the front part of the glasses F. For example, the position of the front part of the glasses F is a position in front of the central position of the state in which the wearer wears the glasses F, such as the bridge FB and the rim FR of the glasses F. For example, in the present embodiment, the front support 21 supports the bridge FB of the glasses F as an example. For example, the front support portion 21 has a U-shape opening upward, and the bridge FB is mounted with the upper side of the glasses F (that is, the upper end side of the rim FR) facing downward. Of course, the bridge FB may be mounted on the front support 21 with the lower part of the glasses F (that is, the lower end side of the rim FR) facing downward.

  For example, the rear support 22 supports the position of the rear part of the glasses F. For example, the position of the rear part of the glasses F is a position behind the central position of the state in which the wearer wears the glasses F, such as the temple FT of the glasses F and the modern FM. For example, in the present embodiment, the case in which the rear support portion 22 supports the modern FM of the glasses F is taken as an example. For example, the rear support portion 22 has a U-shape opening upward, and the modern FM is placed with the upper side of the glasses F (that is, the upper end side of the rim FR) facing downward. Of course, the modern FM may be placed on the rear support 22 with the lower part of the glasses F (that is, the lower end side of the rim FR) facing downward.

<Measurement optical system>
FIG. 3 is a diagram showing an optical system in the eyeglasses mapping information acquisition apparatus 1. For example, the measurement optical system 10 measures the lens characteristic at each portion of the lens LE. For example, the measurement optical system 10 includes a light source 11, a collimator lens 12, an index plate 13, a screen 14, an imaging lens 15, a light receiving element 16, a half mirror 17, and the like. For example, the light source 11 is configured of a first light source 11a and a second light source 11b. For example, the collimator lens 12 makes the measurement light flux emitted from the light source 11 parallel (including substantially parallel) to the optical axis L1. For example, on the index plate 13, a measurement index 70 for measuring the optical characteristics of the lens LE is formed. The details of the measurement index 70 will be described later. For example, the screen 14 is provided at a position spaced apart from the index plate 13 by a predetermined distance. Also, for example, the screen 14 projects an image of the measurement index 70 formed on the index plate 13 (that is, a measurement index image 80 described later). For example, the imaging lens 15 condenses the measurement light flux that has passed through the screen 14. For example, the light receiving element 16 is configured by a charge coupled device (CCD) or a complementary metal oxide semiconductor (CMOS). For example, the half mirror 17 passes or reflects the measurement light beam emitted from the light source 11.

<Light source>
For example, the light source 11 emits a measurement light flux having a specific wavelength band. That is, for example, the light source 11 may be configured by a light source (for example, an LED (Light Emitting Diode) or the like) that emits a measurement light beam having a wide wavelength band. Further, for example, the light source 11 may be configured by a light source (for example, a laser or the like) that emits a measurement light beam having a narrow wavelength band.

  For example, the first light source 11a may be capable of emitting a measurement light flux having a wavelength different from that of the second light source 11b. In this case, it is sufficient that the first light source 11a can emit a measurement light flux in which at least one of the peak of the wavelength and the wavelength band is different from that of the second light source 11b. For example, in the present embodiment, a light source capable of emitting an infrared ray may be used as the first light source 11a. Also, for example, in the present embodiment, a light source capable of emitting visible light may be used as the second light source 11 b.

  For example, in the present embodiment, the first light source 11a is used when acquiring the lens characteristics of the lens LE. Also, for example, in the present embodiment, the second light source 11 b is used when acquiring a frame image 90 (see FIG. 14) of the glasses F described later.

<Measurement index>
FIG. 4 is a diagram for explaining the index plate 13. FIG. 4A is a side view of the index plate 13. FIG. 4B is a plan view of the index plate 13 (a view from the direction of the optical axis L1). For example, the index plate 13 includes a circular member 18. Further, for example, on the index plate 13, a measurement index 70 formed of a reference index 71 and a peripheral index 72 is formed.

  For example, the measurement index 70 passes both the measurement light flux emitted from the first light source 11a and the measurement light flux emitted from the second light source 11b. For example, the measurement index 70 is not configured to completely pass the measurement light flux emitted from the first light source 11a and the measurement light flux emitted from the second light source 11b (that is, the configuration to pass 100% of the measurement light flux) It is also good. For example, the measurement index 70 may be configured to transmit a part of the measurement light flux (for example, a structure to pass 80% of the measurement light flux, a structure to pass 60% of the measurement light flux, etc.).

  For example, the portion other than the measurement index 70 (that is, the hatched portion 19 in FIG. 4) blocks the measurement light flux emitted from the first light source 11a and allows the measurement light flux emitted from the second light source 11b to pass. For example, the hatched portion 19 may not be configured to completely block the measurement light flux emitted from the first light source 11 a (that is, the configuration to pass the measurement light flux at 0%). For example, the hatched portion 19 may be configured to block part of the measurement light flux emitted from the first light source 11a (for example, even if it is configured to pass 10% of measurement flux or 30% to pass measurement flux) Good. Further, for example, the hatched portion 19 may not be configured to completely pass the measurement light beam emitted from the second light source 11 b. For example, the hatched portion 19 may be configured to pass a part of the measurement light beam emitted from the second light source 11 b.

  In addition, for example, when a part of the measurement light flux passes through or shields the measurement index 70 and the oblique line portion 19, the measurement light flux emitted from the first light source 11 a passes the measurement index 70 more than the oblique line 19. Good to have. Further, for example, in such a case, it is preferable that the measurement light flux emitted from the second light source 11 b passes the hatched portion 19 less than the measurement index 70. Further, for example, in such a case, it is preferable that the measurement light flux emitted from the first light source 11a passes the hatched portion 19 less than the measurement light flux emitted from the second light source 11b.

  For example, the measurement index 70 may be formed by a method such as coating (for example, immersion, vapor deposition, painting, etc.), printing (for example, silk printing, etc.), photolithography, etc., or holes (eg, circular holes, square holes) , Slit holes, etc.). In addition, for example, the hatched portion 19 (that is, a portion other than the measurement index 70) may be formed by a method such as coating or printing.

  For example, the reference index 71 is a square point and is disposed at the center of the index plate 13. Of course, the reference index 71 is not limited to a square point, but may be a circle or a triangle. Further, the reference index 71 is not limited to the center of the index plate 13, and may be disposed at any position of the index plate. In addition, although it was set as the structure which provides one reference index in the index plate 13 in a present Example, it is good also as a structure which provides multiple. That is, the reference | standard index | exponent 71 in a present Example should just be distinguishable from the periphery index 72, and a shape, a position, a number, etc. may differ from a present Example.

  For example, the peripheral index 72 is a circular point and is regularly arranged at equal intervals around the reference index 71. Of course, the peripheral index 72 is not limited to a circular point, but may be a square or triangular point. In addition, the peripheral index 72 may be in the form of a parallel cross, a vertical grid, a horizontal grid, a cross grid, or the like consisting of vertical lines and horizontal lines. In the present embodiment, the peripheral indicators 72 are arranged at equal intervals, but the peripheral indicators 72 may be arranged at non-equal intervals.

  For example, by forming the reference index 71 on the index plate 13, it becomes easy to specify the position of each peripheral index image 82 (see FIG. 5) projected on the screen 14. More specifically, the peripheral index image 82 captured in the “0D reference” state in which the glasses F are not mounted corresponds to which of the peripheral index images 82 captured in the state in which the lens LE is mounted. It can be identified.

  FIG. 5 is a view showing a measurement index image 80 projected on the screen 14. FIG. 5A is a measurement index image 80 of the 0D reference state in which the glasses F are not placed, and FIG. 5B is a measurement index image 80 in a state in which the glasses F are placed. In the present embodiment, as the measurement index image 80 in a state in which the glasses F are mounted, a measurement index image in a state in which the glasses F in which a progressive multifocal lens (hereinafter referred to as a progressive lens) is framed is mounted. 80 is taken as an example. For example, in the state where the glasses F are placed, the frame image Fp of the glasses F (for example, in the present embodiment, the upper end image of the rim FR together with the measurement index image 80 (that is, the reference index image 81 and the peripheral index image 82) The lower end image FRd of the FRu and the rim FR is projected on the screen 14.

  For example, in the 0D reference state (see FIG. 5A), the measurement light beam emitted from the first light source 11a passes through the half mirror 17 and becomes parallel to the optical axis L1 by the collimator lens 12 to the index plate 13 It is led and passes through the measurement index 70 formed on the index plate 13. For this reason, on the screen 14, a measurement index image 80 having the same distance between the peripheral index image 82 and the distance between the peripheral indices 72 formed on the index plate 13 is projected.

  For example, in a state in which the glasses F are placed, the measurement light beam emitted from the first light source 11a passes through the half mirror 17 and is guided by the collimator lens 12 to the index plate 13 in parallel with the optical axis L1. , Refracted by the lens LE to diffuse or converge. For example, if the lens LE is a minus lens, the measurement light flux is diffused, and if the lens LE is a plus lens, the measurement light flux is converged. For example, in a state where the glasses F are placed, the light flux thus refracted passes through the measurement index 70 formed on the index plate 13. For this reason, on the screen 14, the measurement indicator image 80 in which the distance between the peripheral index images 82 is wider than the distance between the peripheral indicators 72 formed in the index plate 13 or the measurement index image 80 in which the distance is narrower is projected. . When the lens LE is an astigmatic lens, a measurement index image 80 distorted in an elliptical shape in accordance with the cylindrical diopter and the astigmatic axis angle is projected on the screen. When the lens LE is a progressive lens (see FIG. 5B), a measurement index image 80 deformed in accordance with the lens characteristics of the progressive band is projected on the screen 14.

  For example, the measurement index image 80 projected on the screen 14 is imaged by the light receiving element 16 via the imaging lens 15. The measurement index image 80 captured in the 0D reference state may be stored in the memory 61 in advance.

  For example, the control unit 60, which will be described later, analyzes the measurement index image 80 captured by the light receiving element 16, and measures the lens characteristics at a plurality of locations of the lens LE at one time. For example, the lens characteristics can be calculated as a set of four (at least three) neighboring index images 82 adjacent to each other. Alternatively, the lens characteristic can also be calculated as one set of 3 × 3, 4 × 4, 5 × 5, etc. peripheral index images 82. For details of lens characteristic measurement using the measurement index image 80, refer to Japanese Patent Application Laid-Open No. 2008-241694.

<Drive part>
For example, the drive unit 30 moves the glasses support unit 20 in the front-rear direction (Z direction), the left-right direction (X direction), and the vertical direction (Y direction) with respect to the measurement unit 7. 6 to 10 are schematic configuration diagrams for describing the drive unit 30. FIG. FIG. 6 is a perspective view of the drive unit 30. FIG. FIG. 7 is a right side view of the drive unit 30 (a view from the direction of arrow A in FIG. 2). FIG. 8 is a left side view of the drive unit 30 (a view from the direction of arrow B in FIG. 2). FIG. 9 is a front view of the drive unit 30 (a view from the direction of the arrow C in FIG. 2). FIG. 10 is a rear view of the drive unit 30 (a view from the direction of arrow D in FIG. 2).

  For example, the nut portion 31 is fixed to the lower portion of the measurement portion 7, and the feed screw 32 extending in the X direction is screwed into the nut portion 31. For example, both ends of the feed screw 32 are connected to the base 33 via bearings. Also, for example, the ball bush 34 is fixed to the lower part of the measurement unit 7, and the shaft 35 extending in the X direction penetrates the ball bush. For example, both ends of the shaft 35 are connected to the base 33. For example, the motor 36 is attached to the lower surface of the base 33. For example, the drive shaft of the motor 36 is screwed with the feed screw 32.

  For example, when the motor 36 is driven, the feed screw 32 rotates. For example, since the measuring unit 7 is fixedly arranged, when the feed screw 32 is fed by the nut portion 31, the base 33 moves in the left-right direction (X direction) together with the feed screw 32. For example, at this time, the shaft 35 slides in the ball bush 34. For example, by moving the base 33 in this manner, the glasses support unit 20 can be moved in the left-right direction with respect to the measurement unit 7.

  For example, a bearing support member is fixed to the upper surface of the base 33. For example, the bearing support member is configured of a bearing support member 37 located on the upper front side of the base 33 and a bearing support member 38 located on the upper rear side of the base 33. For example, the bearing support member 37 is provided with a bearing 39, and one end of a feed screw 46 extending in the Z direction is connected to the bearing 39. For example, the bearing support member 38 is also provided with a bearing, through which the feed screw 46 passes. For example, the other end of the feed screw 46 is connected to the drive shaft of the motor 40. For example, the motor 40 is fixed to the bearing support member 38.

  Further, for example, a ball bush support member 41 is fixed to the upper surface of the base 33. For example, the ball bush supporting member 41 is provided with a ball bush, and a shaft 42 extending in the Z direction penetrates the ball bush.

  For example, on the lower surface of the base 43, a nut support member 44 and a shaft support member 45 are fixed. For example, the nut support member 44 is provided with a nut portion, which is screwed with the feed screw 46. For example, the shaft support member 45 is provided with a ball bush, and the shaft 42 passes through the ball bush.

  For example, when the motor 40 is driven, the feed screw 46 is rotated. As a result, the nut portion of the nut support member 44 is fed to the feed screw 46, and the nut support member 44 and the base 43 to which the nut support member 44 is fixed move in the front-rear direction (Z direction). For example, at this time, with the movement of the base 43, the shaft support member 45 fixed to the base 43 slides on the shaft 42. For example, even if the feed screw 46 is rotated by the motor 40, the drive of the motor 40 is not transmitted to the base 33 by the bearing 39, and the base 33 does not move in the front-rear direction (Z direction). For example, the eyeglass support unit 20 can be moved in the front-rear direction with respect to the measurement unit 7 by moving the base 43 in this manner.

  For example, the base 47 has a nut portion, and a feed screw 48 extending in the Y direction is screwed into the nut portion. Also, for example, the base 47 has a ball bush, and each of the shaft 49 and the shaft 50 extending in the Y direction penetrates the ball bush. For example, one end of the feed screw 48 is connected to the base 43 via a bearing provided on the base 43. For example, the other end of the feed screw 48 is connected to the mounting plate 51 via a bearing provided on the mounting plate 51. For example, one end of the shaft 49 is connected to the base 43 via a ball bush provided on the base 43. For example, the other end of the shaft 49 is connected to the mounting plate 52 via a ball bush provided on the mounting plate 52. Similarly, for example, one end of the shaft 50 is connected to the base 43 via a ball bush provided on the base 43. For example, the other end of the shaft 50 is connected to the mounting plate 53 via a ball bush provided on the mounting plate 53. For example, the motor 54 is fixed to the mounting plate 51. For example, the drive shaft of the motor 54 is screwed with the feed screw 48.

  For example, when the motor 54 is driven, the feed screw 48 rotates. As a result, the nut portion of the base 47 is fed to the feed screw 48, so the base 47 moves in the vertical direction (Y direction). For example, at this time, along with the movement of the base 47, the ball bushes of the base 47 slide on the shaft 49 and the shaft 50, respectively. For example, even if the feed screw 48 is rotated by the motor 54, the drive of the motor 54 is not transmitted to the base 43 by the bearing, and the base 43 and the base 33 do not move in the vertical direction (Y direction). For example, the eyeglass support unit 20 can be moved in the vertical direction with respect to the measuring unit 7 by moving the base 47 in this manner.

<Control unit>
FIG. 11 is a diagram showing a control system in the eyeglasses mapping information acquisition apparatus 1. For example, the control unit 60 includes the display 3, the operation button 4, the light source 11 (the first light source 11 a and the second light source 11 b), the light receiving element 16, and the motor (for example, the motor 36, the motor 40, the motor 54) included in the drive unit 30. Etc., and the memory 61 etc. are connected.

  For example, the control unit 60 includes a CPU (processor), a RAM, a ROM, and the like. For example, the CPU controls driving of each member in the eyeglasses mapping information acquisition apparatus 1. Also, for example, the CPU performs various arithmetic processing (for example, calculation of lens characteristics, etc.). For example, the RAM temporarily stores various types of information. For example, programs executed by the CPU are stored in the ROM. The control unit 60 may be configured by a plurality of control units (that is, a plurality of processors).

  For example, the memory 61 is a non-transitory storage medium capable of holding stored contents even when the supply of power is shut off. For example, as the memory 61, a hard disk drive, a flash ROM, and a USB memory detachably mounted on the eyeglasses mapping information acquisition apparatus 1 can be used. For example, the memory 61 stores the measurement index image of the 0D reference state, the measured lens characteristics, and the like.

<Control action>
The control operation of the eyeglasses mapping information acquiring apparatus 1 having the above configuration will be described. For example, the eyeglasses mapping information acquisition apparatus 1 in the present embodiment includes a first mode in which the first light source 11a is irradiated, and a second mode in which the second light source 11b is irradiated. For example, the first mode is selected when acquiring the lens characteristic of the lens LE. For example, when the first mode is selected, the measurement indicator 70 appears on the indicator plate 13 due to the irradiation of the first light source 11a. Therefore, the measurement index image 80 and the frame image Fp of the glasses F are projected on the screen 14. For example, the second mode is selected when aligning the glasses F and the measurement optical system 10 or when acquiring the frame image 90 of the glasses F (see FIG. 14). For example, when the second mode is selected, the measurement indicator 70 does not appear on the indicator plate 13 due to the irradiation of the second light source 11b. Therefore, only the frame image Fp of the glasses F is projected on the screen 14. For example, such switching of the measurement mode is automatically performed by the control unit 60. Of course, the operator may manually switch the measurement mode.

  Hereinafter, description will be made in order using the flowchart shown in FIG. For example, in the present embodiment, the case where a progressive lens is framed in the glasses of the wearer is taken as an example. Of course, the eyeglasses mapping information acquisition apparatus 1 can also measure other lenses (for example, a single focus lens, a double focus lens, etc.) framed in the glasses. Also, for example, in the present embodiment, only the control operation for the left rim FRL of the glasses F is described, and the control operation for the right rim FRR of the glasses F is omitted. The control operation of the right rim FRR of the glasses F can be considered in the same manner as the control operation of the left rim FRL of the glasses F.

  First, the operator receives the glasses from the wearer and acquires the glasses image (see the first glasses image 100a shown in FIG. 18) of the glasses F currently worn by the wearer. For example, the operator places the received spectacles F on the spectacles supporting unit 20, and selects an unshown start button for starting the measurement of the progressive lens from the operation buttons 4 displayed on the display 3. For example, by this, the control unit 60 sets the second mode, turns on the second light source 11b, and irradiates the measurement light beam toward the lens LE.

<Alignment of glasses and measurement optical system (S1)>
For example, the control unit 60 moves the measurement unit 7 and the glasses support unit 20 to an initial position so as to have a predetermined positional relationship. For example, the initial position in the present embodiment is a position where the optical axis L1 of the measurement optical system 10 passes near the center of the lens LE.

  First, for example, the control unit 60 moves the glasses support unit 20 in the left-right direction. For example, the amount of movement of the glasses support unit 20 in the lateral direction is set based on the pupil distance of the wearer (that is, the sum of the left pupil distance and the right pupil distance of the wearer). For example, the interpupillary distance of the wearer may be obtained in advance using a spectacles-wearing image analyzer (for example, see JP-A-2015-179254), a PD meter, or the like. For example, the control unit 60 moves the glasses support unit 20 to the right by the distance between left pupils, with the position where the left and right centers of the front support 21 and the left and right centers of the measurement unit 7 coincide as a base point. Thereby, the optical axis L1 of the measurement optical system 10 is aligned near the left and right center of the lens LE framed in the left rim FRL of the glasses F. Note that, for example, the control unit 60 may move the glasses support unit 20 in the left and right direction based on the average interpupillary distance of the wearer.

  Next, for example, the control unit 60 moves the glasses support unit 20 in the vertical direction. For example, the control unit 60 vertically moves the glasses supporting unit 20 so that the light receiving element 16 can detect both the upper end image FRu and the lower end image FRd of the rim FR in the frame image Fp of the glasses F projected on the screen 14 Move it. For example, the control unit 60 detects the upper end image FRu and the lower end image FRd of the rim FR by performing image processing on the light receiving image 65 (see FIG. 13) captured by the light receiving element 16. For example, in this case, the control unit 60 may be configured to perform edge detection to detect rising and falling of the luminance in the light reception image 65.

  For example, FIG. 13 is a view showing an example of the light reception image 65 at the time of setting the second mode. FIG. 13A is a light reception image 65 including only the top image FRu of the rim FR. FIG. 13B is a light reception image 65 including only the lower end image FRd of the rim FR. FIG. 13C is a light reception image 65 including both the upper end image FRu and the lower end image FRd of the rim FR. For example, the frame image Fp of the glasses F appears as a shadow on the light receiving image 65. Therefore, in the present embodiment, the luminance of the portion where the frame image Fp is located becomes smaller (darker) than the luminance of the peripheral portion of the frame image Fp. That is, at the portion where the frame image Fp of the glasses F is located, the luminance of the light reception image 65 falls.

  For example, the control unit 60 detects the fall of the luminance in the vertical direction at the center line 66 located at the left and right center of the light reception image 65. Further, for example, the control unit 60 includes a scanning line 67 located at a predetermined distance leftward from the center line 66 and a scanning line 68 located at a predetermined distance rightward from the center line 66. , And at least one of them is scanned to detect the fall of the luminance in the vertical direction. For example, the predetermined distance may be set by the operator to set an arbitrary distance. Further, for example, the predetermined distance may be set to a distance that can correspond to various glasses by experiment, simulation, or the like. In the following description, the processing in the case where the controller 60 detects the fall of the luminance in the center line 66 and the scanning line 67 will be described as an example.

  For example, in the light reception image 65, the control unit 60 detects that the frame image Fp of the glasses F detected when the falling position of the brightness of the center line 66 is lower than the falling position of the brightness of the scanning line 67. It is determined that the top image FRu of the rim FR is determined, and the glasses support unit 20 is moved downward. Also, for example, in the light reception image 65, the control unit 60 detects the frame image of the glasses F detected when the falling position of the brightness of the center line 66 is higher than the falling position of the brightness of the scanning line 67. It is determined that Fp is the lower end image FRd of the rim FR, and the eyeglass support unit 20 is moved upward. Further, for example, when two falling positions of the luminance of the center line 66 appear in the light reception image 65, the control unit 60 determines that both the upper end image FRu and the lower end image FRd of the rim FR are detected, The movement of the glasses support unit 20 in the vertical direction is ended. Thus, the optical axis L1 of the measurement optical system 10 is aligned near the upper and lower centers of the lens LE. The received light image 65 may be a moving image. In this case, the movement of the frame image Fp of the glasses F may be captured in real time by moving image processing.

  Next, for example, the control unit 60 moves the glasses support unit 20 in the front-rear direction. For example, the control unit 60 moves the eyeglass support unit 20 in the front-rear direction such that the contact pin 6 contacts the rear surface of the lens LE. For example, the contact pin 6 is provided with a sensor (not shown) capable of detecting contact with the lens LE. For example, as a sensor not shown, a pressure sensor, a contact sensor, etc. can be used. For example, in the case of a pressure sensor, the electrical resistance value flowing in the sensor changes according to the pressure from the outside. For example, in the memory 61, the electric resistance value in the state where there is no external pressure (that is, the state where the contact pin 6 and the lens LE are not in contact) may be stored in advance. For example, the control unit 60 determines that the contact pin 6 is in contact with the lens LE by comparing the changed electric resistance value with the electric resistance value stored in advance. End the movement in the back and forth direction.

  For example, when the eyeglass support unit 20 is moved to the initial position as described above, the screen 14 projects the upper end image FRu of the rim FR and the lower end image FRd of the rim FR. For example, the control unit 60 receives the frame image Fp of the glasses F projected on the screen 14 by the light receiving element 16, and the light reception image obtained by this (that is, the light reception image 65 in the state of FIG. The frame image 90 (see FIG. 14) of the glasses F is acquired using this.

<Acquisition of frame image (S2)>
FIG. 14 is a view showing a frame image 90 of the glasses F. As shown in FIG. For example, the control unit 60 acquires an image obtained by extracting the frame image Fp of the glasses F from the light reception image 65 as the frame image 90 of the glasses F (S2). For example, in the present embodiment, the control unit 60 performs image processing on the received light image 65 to extract the frame image Fp of the glasses F. More specifically, for example, the control unit 60 acquires a luminance value for each pixel position of the received light image 65, and extracts a frame image Fp of the glasses F based on the luminance value. For example, in this case, the control unit 60 may determine that the pixel position at which the luminance value is smaller than the threshold value set in advance by experiments or simulations is the frame image Fp of the glasses F. Of course, the control unit 60 may improve the extraction accuracy of the frame image Fp by binarizing the detected luminance value based on the threshold value. For example, this allows the control unit 60 to acquire the frame image 90 of the glasses F. For example, the frame image 90 of the glasses F is stored in the memory 61.

  For example, FIG. 15 is a view showing a light reception image 69 at the time of setting the first mode. For example, when acquiring the frame image 90 of the glasses F, the control unit 60 switches the measurement mode from the second mode to the first mode. As a result, the first light source 11a is turned on, and the measurement light beam is emitted toward the lens LE. For example, the upper end image FRu of the rim FR and the lower end image FRd of the rim FR, and the measurement index image 80 which has passed through the lens LE and the index plate 13 are projected on the screen 14 (see FIG. 5B). For example, the control unit 60 acquires the light receiving image 69 captured by the light receiving element 16.

<Acquisition of lens characteristics (S3)>
For example, the control unit 60 measures the lens characteristic of the lens LE from the interval, the deformation amount, and the like of the peripheral index image 82 in the light reception image 69 (S3). For example, in a portion where the index plate 13 and the frame of the glasses F overlap in the front-rear direction, the measurement light beam is blocked by the frame of the glasses F, so a part of the peripheral index image 82 projected on the screen 14 is missing There is a case. That is, in the peripheral index image 82 located around the frame image Fp of the glasses F, the frame image Fp and the peripheral index image overlap and become a non-circular point (for example, a point missing in a semicircular shape, etc.) There is a case. For example, in the region inside the frame image Fp of the glasses F, the lens characteristics of the lens LE are obtained, but in the region outside the frame image Fp of the glasses F, a lens characteristic of about 0 D is obtained.

  Therefore, for example, the control unit 60 may calculate the lens characteristic of the lens LE in a region inside the frame image Fp of the glasses F. The control unit 60 predicts the positional relationship between the peripheral index image missing due to the frame image Fp of the glasses F and the peripheral index image not visible overlapping with the frame image Fp of the glasses F from the peripheral index image 80 around The lens characteristics may be calculated using these. For example, when the lens characteristic of the lens LE is measured, the control unit 60 stores the result in the memory 61.

<Acquisition of mapping image (S4)>
For example, the control unit 60 acquires a mapping image 95 indicating lens characteristics based on the lens characteristics measured by the measurement optical system 10 (S4). FIG. 16 shows an example of the mapping image 95. As shown in FIG. FIG. 16A is a mapping image 95 in which an equal power line 96 is created based on the spherical power S, and FIG. 16B is a mapping image 95 in which an equal power line 96 based on the cylindrical power C is generated. Although the description is omitted in the present embodiment, the control unit 60 may acquire a mapping image in which isopower lines are created based on the astigmatic axis angle A, the prism amount Δ, and the like.

  For example, the equal power line 96 is a curve connecting measurement positions at which the measurement results of the spherical power S or the cylindrical power C are equal. For example, the control unit 60 creates equal power lines 96 based on the spherical power S at a plurality of locations on the received light image 69. Similarly, for example, the control unit 60 creates an equal frequency line 96 based on cylindrical frequencies C at a plurality of locations on the received light image 69. For example, equal frequency lines 96 are created at predetermined frequency intervals (for example, 0.25 D intervals, 0.5 D intervals, etc.). That is, a plurality of equal frequency lines 96 are created on the received light image 69. Therefore, the operator can visually grasp the change of the power in the progressive lens.

  For example, in the present embodiment, an image in which the equal power line 96 is created on the light reception image 69 is acquired as the mapping image 95 indicating the lens characteristic of the lens LE. For example, the control unit 60 stores such a mapping image 95 in the memory 61. Note that, for example, the control unit 60 may be configured to create a graphic in which the areas having the same lens characteristics are color-coded on the light reception image 69 and store the graphic in the memory 61 as a mapping image.

<Obtaining of glasses image (S5)>
For example, the control unit 60 associates the mapping image 95 with the frame image 90 of the glasses F. Also, for example, the control unit 60 acquires the glasses image 100 in which the mapping image 95 and the frame image 90 are associated (S5). For example, in the present embodiment, a case where the control unit 60 associates the mapping image 95 and the frame image 90 by superimposing each other and acquires the glasses image 100 in which the mapping image 95 and the frame image 90 are superimposed is taken as an example. I will list.

  FIG. 17 shows an example of an eyeglass image 100 in which the mapping image 95 and the frame image 90 are superimposed. For example, the mapping image 95 and the frame image 90 are acquired based on the light reception image 65 and the light reception image 69 captured by the light receiving element 16. Therefore, the number of pixels in these images is the same (ie, pixel to pixel), and each pixel position of the mapping image 95 corresponds to each pixel position of the frame image 90. For example, the control unit 60 superimposes these images so that each pixel position of the mapping image 95 and each pixel position of the frame image 90 coincide with each other. In the present embodiment, as described above, the lens characteristic in the region inside the frame image Fp of the glasses F is acquired, and the equal power line 96 is created. Therefore, by superimposing the mapping image 95 and the frame image 90, it is possible to obtain the glasses image 100 in which the equal frequency line 96 is superimposed on the region inside the frame image Fp. For example, the acquired eyeglass image 100 is stored in the memory 61.

  For example, the operator can use the eyeglasses mapping information acquisition apparatus 1 to acquire an eyeglass image for the eyeglasses currently worn by the wearer as described above. Thereafter, the operator frames the progressive lens suitable for the wearer into the frame of the spectacles F selected by the wearer using the spectacle lens processing device or the like to produce new spectacles F. Also, for example, the operator obtains a glasses image (see the second glasses image 100b shown in FIG. 18) for the glasses newly prepared by the wearer in the same manner as the above-described operation. For example, when the operator obtains a plurality of glasses images 100, the operator selects a comparison display button (not shown) from the operation buttons 4 displayed on the display 3. For example, by this, the control unit 60 outputs a plurality of glasses images.

<Output of glasses image (S6)>
For example, the control unit 60 outputs the plurality of acquired eyeglass images 100 in a comparable manner (S6). For example, the plurality of eyeglass images may be at least two eyeglass images. Also, for example, the plurality of glasses images may be glasses images in which at least one of the lens characteristics, the frame, and the positional relationship between the mapping image 95 and the frame image 90 is different. For example, the control unit 60 in the present embodiment includes two eyeglass images of a first eyeglass image 100a for the eyeglasses currently worn by the wearer and a second eyeglass image 100b for the eyeglasses newly produced by the wearer. Output comparably.

  For example, a plurality of glasses images are comparably output by display on a display, a tablet terminal or the like, printing using a printer or the like, storage in an external memory (for example, a USB memory or the like), or the like. In the present embodiment, a case where the control unit 60 displays the plurality of glasses images 100 on the display 3 in a comparable manner will be described as an example.

  FIG. 18 is a view showing an example of the comparison image 110 displayed on the display 3. FIG. 18A is a comparison image 110 of a plurality of glasses images, and FIG. 18B is a comparison image 110 in which the marker marks 120 are superimposed on a plurality of glasses images. For example, the comparative image 110 in the present embodiment includes the first eyeglass image 100a and the second eyeglass image 100b, and these eyeglass images are displayed in parallel.

  Note that, for example, in the comparison image 110, the marker mark 120 based on the eye point data of the wearer may be superimposed on at least one eyeglass image in the plurality of eyeglass images 100 (see FIG. 18B). For example, the marker mark 120 is an eyepoint mark 121 indicating the eyepoint position of the wearer, a distance eyepoint mark 122 calculated based on the eyepoint position, a near vision eyepoint mark 123 and the like. For example, the eye point position of the wearer may be measured in advance using another device (for example, an eyeglass wearing image analysis device or the like). Also, for example, the eye point position of the wearer may be marked with the pupil position of the wearer on the lens LE using a pen or the like, and the position may be measured by a ruler or the like.

  For example, the control unit 60 acquires an eyepoint position from a measurement value or the like input from the operation button 4 by the operator, and calculates a far vision eyepoint position and a near vision eyepoint position. Also, for example, the control unit 60 outputs marker marks 120 such as the eyepoint mark 121, the far vision eyepoint mark 122, and the near vision eyepoint mark 123 together with the eyeglass image 100.

  For example, since the eyeglass image 100 is created from the light reception image when the eyeglass support unit 20 is moved based on the distance between the pupils of the wearer, the eye point position of the wearer is on the left and right center of the eyeglass image 100. It is located in For example, the control unit 60 performs image processing such as edge detection on the left and right centers of the glasses image 100 to detect the lower end of the rim FR. Also, for example, the control unit 60 determines the eye point position based on the distance from the lower end of the rim FR to the pupil position (that is, PD height). For example, the number of pixels corresponding to the actual PD height in the eyeglass image 100 may be set in advance by experiment, simulation, or the like. Thus, the eye point position on the eyeglass image can be known, and the marker mark 120 can be superimposed on the eyeglass image 100 and output.

  For example, by displaying the comparative image 110 on the display 3 in this manner, the operator visually recognizes the difference in lens characteristics between the glasses currently worn by the wearer and the glasses newly produced by the wearer. You will be able to grasp. In addition, the operator changes the position of the distance part and the near part in the glasses currently worn by the wearer and the glasses newly produced by the wearer, and changes in the appearance due to differences in distortion, etc. You will be able to communicate to the wearer in an easy-to-understand manner.

  In the above description, the case of acquiring eyeglass images of the eyeglasses currently worn by the wearer and the eyeglasses completed is described as an example. For example, the eyeglasses mapping information acquisition apparatus 1 acquires an eyeglass image showing the positional relationship between the lens characteristics and the frame in the eyeglasses F to be newly produced by the wearer, and compares it with the eyeglass image of the eyeglasses currently worn You may The control operation of the eyeglasses mapping information acquisition apparatus 1 in such a case will be described below.

  For example, the operator acquires the glasses image 100a of the glasses F currently worn by the wearer as described above. Also, for example, the operator causes the wearer to wear the spectacles F selected by the wearer to produce new spectacles, and measures the spectacle wearing parameter using the spectacle wearing image analysis device or the like. For example, with this, the pupil position of the wearer with respect to the glasses F can be detected, and the eye point position of the wearer can be obtained. For example, when the operator inputs a measured value from the operation button 4, the control unit 60 stores the measured value in the memory 61.

  Next, the operator obtains a frame image of the glasses F which the wearer has selected to produce new glasses, and a mapping image of the progressive lens to be provided to the wearer. For example, the operator selects a frame image 90a (dotted line in FIG. 19) corresponding to the frame of the glasses F selected by the wearer from a database in which frame images of a plurality of glasses are stored in advance. For example, a database of frame images may be created in advance by acquiring frame images by measuring each frame shape in a plurality of glasses, and using these images. For example, when the frame image 90a (see FIG. 19) is selected, the control unit 60 uses the measurement values stored in the memory 61 to calculate the eyepoint position i1 of the wearer on the frame image 90a. For example, a database of frame images may be created based on frame design data used when manufacturing a frame, and is not limited to the present embodiment.

  Also, for example, the operator may use the mapping image 95a of the progressive lens to be provided to the wearer from a database in which a plurality of mapping images showing lens characteristics of the lens (for example, the lens in this embodiment) are stored in advance. 19) is selected. For example, a database of mapping images may be created by acquiring mapping images in advance by measuring lens characteristics of a plurality of lenses, and using these images.

  In addition, for example, such a mapping image may be acquired using the spectacles mapping information acquisition apparatus 1 demonstrated in the present Example. Also, for example, such a mapping image may be acquired using the eyeglass mapping information acquisition apparatus 1 separately provided with an optical system capable of detecting a hidden mark, or an optical system capable of detecting a hidden mark. And the measurement optical system 10 may be acquired using the eyeglass mapping information acquisition apparatus 1. Of course, such a mapping image may be acquired using another device.

  For example, the lens image and the eye point position i2 of the lens may be stored in the mapping image on the database. For example, the eyepoint position i2 of the lens can be determined from the position of the hidden mark applied to the lens. Therefore, for example, the mapping image may be acquired using an optical system capable of detecting a hidden mark in the eyeglasses mapping information acquisition device 1 and using this. Also, for example, the mapping image may be acquired using the eyeglass mapping information acquisition apparatus 1 in which the optical system capable of detecting the hidden mark and the measurement optical system 10 are used in combination. Of course, the mapping image may be acquired using another device equipped with an optical system capable of detecting a hidden mark. For example, the control unit 60 calculates the eyepoint position i2 of the lens on the mapping image 95a.

  Note that, for example, a database of mapping images may be created based on lens design data used when manufacturing a lens. In this case, since the eyepoint position i2 of the lens can be obtained from lens design data, the eyepoint position of the lens can be stored together with the mapping image.

  For example, the control unit 60 takes in a frame image 90a of the corresponding glasses F and a mapping image 95a of the progressive lens to be provided to the wearer from each database. Also, for example, the control unit 60 sets the frame image 90a and the mapping image 95a such that the eye point position i1 in the frame image 90a of the glasses F and the eye point position i2 in the mapping image 95a of the progressive lens coincide with each other. Make it overlap. Thus, the control unit 60 acquires the eyeglass image 100c indicating the positional relationship between the lens characteristics and the frame in the eyeglasses F to be newly manufactured by the wearer.

  For example, when the control unit 60 acquires the respective glasses images, as described above, the glasses image 100a of the glasses currently worn by the wearer and the glasses image 100c in the glasses F to be newly produced by the wearer And output comparably. FIG. 19 is a view showing a modified example of the comparison image 110. As shown in FIG. For example, on the display 3, the glasses image 100a and the glasses image 100c are displayed in parallel. In addition, although illustration is abbreviate | omitted in a present Example, the mark mark 120 may be superimposed and displayed on these images.

  For example, by displaying the comparison image 110 on the display 3 in this manner, the operator can determine whether the distance portion or the near portion of the progressive lens fits in the frame. If the distance and near parts do not fit within the frame, it may be suggested to the wearer to change the selected progressive lens or to change the selected eyeglass frame. Also, when the distance and near parts do not fit within the frame, the arrangement of the lens characteristics with respect to the frame may be adjusted. For example, in this case, at least one of the frame image 90a of the glasses F and the mapping image 95a of the progressive lens may be moved by operating the movement button 111 displayed in the comparison image 110. .

  For example, the operator determines the positional relationship between the lens characteristic and the frame in the glasses F to be newly manufactured by the wearer, and selects the determination button (not shown) from the operation buttons 4. For example, when the determination button is selected, the control unit 60 outputs data regarding the positional relationship between the lens characteristic and the frame in the eyeglass image 100c. For example, the operator uses this data in the eyeglass lens processing apparatus or the like to frame the progressive lens in the frame of the eyeglass F selected by the wearer, and produce new eyeglasses F. After this, the operator uses the glasses mapping information acquisition apparatus 1 to acquire the glasses image 100b for the manufactured glasses, and the difference in the degree of visibility with the glasses currently worn by the wearer, etc., as scheduled You may also check if the glasses have been produced.

  In the above, the configuration for outputting the glasses image in the glasses currently worn by the wearer and the glasses to be newly produced is described as an example, but the present invention is not limited to this. For example, when there are a plurality of eyeglass frames selected by the wearer, etc., an eyeglass image obtained by combining the mapping image of the lens and the plurality of frame images may be obtained and output so as to be comparable. Good. For example, even with the same progressive lens, it is possible to grasp the positional relationship of the lens characteristics, such as the near vision part does not cover in one eyeglass frame and the near vision part in the other eyeglass frame. Therefore, the operator can select the glasses frame suitable for the wearer to produce the glasses.

  As described above, for example, the eyeglasses mapping information acquiring apparatus 1 according to the present embodiment acquires a mapping image indicating lens characteristics and a frame image of eyeglasses, respectively, and an eyeglass image in which the mapping image and the frame image are associated To get By this, the operator can grasp how the lens characteristic is positioned with respect to the frame. In addition, the eyeglasses mapping information acquisition device 1 comparesably outputs a plurality of eyeglasses images different in at least one of the lens characteristics, the frame, and the positional relationship between the mapping image and the frame image. This allows the operator to select a good combination of eyeglass frame and lens. In addition, the operator can easily compare changes such as the degree of visibility due to the difference in the glasses.

  Also, for example, the eyeglasses mapping information acquisition apparatus in the present embodiment acquires an eyeglass image in which the mapping image and the frame image are superimposed. This allows the operator to determine whether the positional relationship between the eyeglass frame and the lens is good. Also, the operator can easily determine the position of the lens characteristic with respect to the frame. In particular, when a progressive lens is measured, it can be easily determined whether its distance and near parts are within the frame.

  Also, for example, the eyeglasses mapping information acquisition device in the present embodiment outputs a plurality of eyeglasses images in parallel. By this, the operator can easily consider a good combination of the eyeglass frame and the lens from the plurality of eyeglass images. In addition, the operator can easily grasp how the lens characteristics, the degree of appearance, and the like have changed from the plurality of glasses images. In addition, the operator can easily explain to the wearer the differences in lens characteristics, appearance, and the like.

  Also, for example, the eyeglasses mapping information acquisition device in the present embodiment displays a plurality of eyeglass images comparably. Thereby, the operator can compare the glasses images and select a good combination of the glasses frame and the lens. In addition, the operator can compare the glasses images with one another to easily understand differences in lens characteristics, appearance, and the like.

  Also, for example, the eyeglasses mapping information acquisition apparatus in the present embodiment acquires eyepoint data of the wearer, and superimposes a marker mark based on the eyepoint data on at least one eyeglass image in a plurality of eyeglass images. In addition, the eyeglasses mapping information acquisition device in the present embodiment outputs a plurality of eyeglasses images in a comparable manner and outputs a marker mark superimposed on at least one eyeglasses image. By this, the operator can grasp where the eye point position etc. of the wearer is located with respect to the frame of the glasses and easily judge whether it is a combination of the spectacle frame and the lens which is good for the wearer. it can.

<Modification example>
In the present embodiment, the glasses image showing the positional relationship between the lens characteristics and the frame in the glasses F scheduled to be newly prepared by the wearer is acquired by fetching the mapping image and the frame image from the database. Although the configuration has been described by way of example, it is not limited thereto. For example, when acquiring such an eyeglass image, at least one of the mapping image and the frame image may be fetched from the database, and the other may be acquired by measurement. Of course, both the mapping image and the frame image may be obtained by measurement.

  For example, in the case of capturing a frame image from a database and acquiring a mapping image by measurement, the operator selects a frame image corresponding to the frame of the glasses F selected by the wearer from the database. For example, the control unit 60 takes in the frame image 90a from the database, and calculates the eyepoint position i1 of the wearer on the frame image 90a in the same manner as described above. Also, for example, the operator measures the lens characteristics of the progressive lens to be provided to the wearer using the eyeglasses mapping information acquisition apparatus 1. For example, the control unit 60 may obtain the geometric center position O (see FIG. 20) of the lens using the result of measuring the lens characteristics of the lens. Thus, the geometric center position O of the lens on the mapping image 95a is acquired together with the mapping image 95a indicating the lens characteristics of the lens. The eyeglasses mapping information acquisition apparatus 1 may be configured to obtain the eye point position i2 on the mapping image 95a as described above.

  FIG. 20 shows an example of the eyeglass image 100d. For example, the control unit 60 superimposes the frame image 90a and the mapping image 95a such that the eye point position i1 in the frame image 90a of the glasses F and the geometric center position O in the mapping image 95a of the progressive lens coincide with each other. Let By this, the control unit 60 may obtain the glasses image 100d indicating the positional relationship between the lens characteristics and the frame in the glasses F scheduled to be newly manufactured by the wearer.

  For example, when the control unit 60 acquires eyeglass images of the eyeglass image 100a for the eyeglasses currently worn by the wearer and the eyeglass image 100d for the eyeglasses scheduled to be newly produced by the wearer, the control portion 60 The glasses image 100d is output in a comparable manner as described above. Of course, the operator may operate the move button 111 (see FIG. 19) while looking at the display 3 to move at least one of the frame image 90a and the mapping image 95a. For example, since the superimposed position of the frame image 90a and the mapping image 95a in the glasses image 100d is changed by this, the control unit 60 may output data in which the positional relationship between the lens characteristic and the frame is changed.

  For example, even if the mapping image is fetched from the database and the frame image is acquired by measurement, the geometric center position O or the eye point position i2 on the mapping image 95a and the eye point position i1 on the frame image 90a And can be used to superimpose and output these images in a comparable manner.

  In the present embodiment, when superimposing a frame image and a mapping image, a configuration in which the eye point position (that is, eye point positions i1 and i2) and the geometric center position O are used as a reference However, the present invention is not limited thereto. For example, if the frame image and the mapping image are superimposed, it is possible to determine how the positional relationship between the frame image and the mapping image has changed when at least one of the frame image and the mapping image is moved. It may be anywhere. For example, the reference at the time of superposing the frame image and the mapping image may be the boxing center position of the frame in the glasses F or the like. For example, in this case, there is a configuration in which the boxing center position on the frame image and the eye point position i2 on the mapping image are superimposed so as to coincide with each other. Also, for example, in this case, there is a configuration in which the boxing center position on the frame image and the geometric center position O on the mapping image are superimposed to coincide with each other.

  In the present embodiment, when acquiring the frame image 90 of the glasses F, the configuration using the light reception image 65 captured by the light receiving element 16 included in the measurement optical system 10 has been described as an example, but the present invention is not limited thereto . For example, the frame image 90 of the glasses F may be acquired using an optical system for imaging glasses different from the measurement optical system 10 (hereinafter referred to as a glasses imaging optical system). For example, the eyeglass photographing optical system includes at least a lens and a light receiving element, and photographs the eyeglass F from the front surface of the eyeglass F (that is, the convex side of the lens LE framed in the eyeglass F). For example, with this, the control unit 60 may acquire one image obtained by photographing the left rim FRL of the glasses F and the right rim FRR of the glasses F. Of course, the control unit 60 may capture the left rim FRL of the glasses F and the right rim FRR of the glasses F to obtain two images. For example, the control unit 60 may acquire the frame image 90 of the glasses F by performing image processing on the image acquired in this manner.

  For example, in the case of superimposing the frame image acquired by the glasses photographing optical system and the mapping image 95 acquired by the measurement optical system 10, a reference position serving as a reference in these images may be set. For example, such a reference position may be set based on the pupil distance of the wearer and the PD height of the wearer. For example, with respect to a frame image acquired by the eyeglass photographing optical system, the control unit 60 is at a position separated from the center of the bridge FB by the left interpupillary distance or the right interpupillary distance and PD high from the lower end of the rim FR. The position separated by a distance is set as the reference position. For example, in the frame image acquired by the eyeglass photographing optical system, the number of pixels corresponding to the actual inter-pupil distance and the PD height may be set in advance by experiment, simulation or the like.

  In addition, for example, the control unit 60 sets, for the mapping image acquired by the measurement optical system 10, a position that is at the left and right center of the mapping image and is separated by PD height from the lower end of the rim FR as a reference position Do. For example, since the mapping image is created from the light reception image 69 when the eyeglass support unit 20 is moved based on the inter-pupil distance, the pupil position of the wearer is located at the center on the left and right of the mapping image. Note that, for example, in the mapping image acquired by the measurement optical system, the number of pixels to which the actual PD height corresponds may be set in advance by experiment, simulation or the like.

  For example, the control unit 60 causes the reference positions of the frame image acquired by the eyeglass photographing optical system and the mapping image acquired by the measurement optical system 10 to coincide with each other. Also, for example, the control unit 60 may be configured such that the frame image Fp of the glasses F in the frame image acquired by the eyeglass photographing optical system and the mapping image acquired by the measurement optical system 10 have the same size. Enlarge or reduce each image. For example, the control unit 60 may superimpose the frame image acquired by the glasses photographing optical system and the mapping image acquired by the measurement optical system 10 in this manner.

  In the present embodiment, the configuration in which the glasses F and the measurement optical system 10 are aligned by moving the glasses supporting unit 20 with respect to the measurement unit 7 has been described as an example, but the present invention is not limited thereto. I will not. For example, instead of moving the glasses support unit 20, the glasses F and the measurement optical system 10 may be aligned by moving the measurement unit 7.

  In the present embodiment, the configuration in which the glasses F and the measurement optical system 10 are aligned is described as an example so that both the upper end image FRu and the lower end image FRd of the rim FR can be detected from the received light image 65. Is not limited to this. For example, when the vertical width of the rim FR (that is, the width from the upper end to the lower end of the rim FR) is long glasses F, light reception is divided into multiple times such as the upper end side of the rim FR and the lower end side of the rim FR An image may be acquired.

  Further, in the present embodiment, the configuration for detecting the falling position of the luminance in the center line 66 and at least one of the scanning line 67 and the scanning line 68 has been described as an example with respect to the light reception image 65. It is not limited to. For example, the control unit 60 may set a plurality of scanning lines at predetermined intervals for the light reception image 65, and may detect the fall position of the luminance on the scanning line. In this case, the edge is detected from the fall of the luminance of each scanning line, and the frame image Fp of the glasses F is detected. For example, the control unit 60 may determine the upper end image FRu of the rim FR and the lower end image FRd of the rim FR from the frame image Fp obtained in this manner.

  In addition, in a present Example, although the structure which acquires a lens characteristic in the area | region inside the flame | frame in the spectacles F was mentioned as an example, and demonstrated, it is not limited to this. For example, the eyeglasses mapping information acquisition apparatus 1 may not necessarily measure the entire area inside the frame as in the present embodiment. For example, in this case, the eyeglasses mapping information acquiring apparatus 1 may be configured to acquire lens characteristics of a region including at least the distance portion, the progressive zone, and the near portion of the lens LE.

  Further, in the present embodiment, the lens characteristic is measured in the region inside the frame in the glasses F, and the configuration for acquiring the mapping image 95 has been described as an example, but the present invention is not limited thereto. For example, when the peripheral index image missing due to the frame image Fp of the glasses F or the invisible peripheral index image is predicted from the interval of the peripheral index images around, etc., the lens in the region inside the frame image Fp of the glasses F Apart from the characteristics, the lens characteristics in the region outside the frame image Fp of the glasses F are also acquired, and the equal power line 96 is created. For example, in this case, the glasses image 100 in which the mapping image 95 is displayed may be output also for the area outside the frame image Fp. Also, for example, in this case, image processing or the like may be performed and the mapping image 95 in the area outside the frame image Fp may not be output.

  Note that, for example, in the present embodiment, the glasses mapping information acquisition apparatus 1 has exemplified the configuration for acquiring the mapping image 95 of the glasses F, but the present invention is not limited to this. For example, the eyeglasses mapping information acquisition apparatus 1 may be configured to receive a mapping image acquired by another apparatus, or may be acquired by reading a mapping image stored in an external memory or the like. . Further, for example, the eyeglasses mapping information acquisition apparatus 1 may be configured to acquire a mapping image by capturing a corresponding mapping image from a plurality of mapping images stored in advance in a database.

  Also, for example, in the present embodiment, the configuration in which the eyeglasses mapping information acquisition device 1 acquires the frame image 90 of the eyeglasses F is described as an example, but the present invention is not limited thereto. For example, the eyeglasses mapping information acquisition apparatus 1 may be configured to receive a frame image acquired using another apparatus, a detection result of a frame, and the like. Furthermore, for example, the eyeglasses mapping information acquisition apparatus 1 may be configured to acquire a frame image of the eyeglasses F by reading a frame image stored in an external memory, a detection result of a frame, or the like. Also, for example, the eyeglasses mapping information acquisition apparatus 1 may be configured to acquire frame images by capturing corresponding frame images from a plurality of frame images stored in advance in a database. In this case, information indicating the frame shape of the glasses may be acquired as a frame image. In this case, information indicating the shape of the lens framed in the glasses may be acquired as a frame image.

  For example, in the present embodiment, a database in which a plurality of mapping images are stored may be stored in the memory 61 included in the eyeglasses mapping information acquisition device 1 or a memory included in another device (for example, personal It may be stored in a computer server or the like. Similarly, in the present embodiment, a database in which a plurality of frame images are accumulated may be stored in the memory 61 provided in the eyeglasses mapping information acquisition device 1 or in the memory provided in another device. It is also good.

  In addition, for example, the eyeglasses mapping information acquisition apparatus 1 in the present embodiment may include a selection unit for selecting a corresponding mapping image from the mapping image database. Also, for example, the eyeglasses mapping information acquisition apparatus 1 in the present embodiment may be provided with selection means for selecting a corresponding frame image from the frame image database.

  For example, such selection means may be an operation unit. In this case, the corresponding mapping image or frame image may be selected from the database by operating the operation unit (for example, the display 3 in the present embodiment). For example, the control unit 60 may call a corresponding mapping image from the mapping image database based on the selected selection signal, and acquire this. Also, for example, the control unit 60 may call a corresponding frame image from the frame image database based on the selected selection signal, and acquire this.

  Also, for example, such selection means may be a one-dimensional code (for example, a barcode or the like) or a two-dimensional code (for example, a QR code (registered trademark) or the like). In this case, the corresponding mapping image or frame image may be selected from the database by reading the one-dimensional code or the two-dimensional code. For example, the control unit 60 may obtain a corresponding mapping image by calling and receiving a mapping image associated with each code from the mapping image database based on the selected selection signal. Also, for example, based on the selected selection signal, the control unit 60 calls a frame image associated with each code from the frame image database, receives the signal, and acquires the corresponding frame image. It is also good.

  In the present embodiment, as the glasses image in which the mapping image and the frame image are associated, the configuration for acquiring the glasses image 100 in which the mapping image 95 and the frame image 90 are superimposed has been described as an example. I will not. For example, as the eyeglass image 100, any image may be used as long as the positional relationship between the mapping image 95 and the frame image 90 is associated. For example, in this case, the glasses image 100 may indicate the position of the frame of the glasses F and the lens characteristics.

  In addition, in a present Example, although the structure which displays the several spectacles image 100 on the display 3 was mentioned as an example and demonstrated, it is not limited to this. For example, the eyeglasses mapping information acquisition device 1 may be configured to display one eyeglass image 100 on the display 3. In this case, by switching the display screen of the display 3 using the operation button 4 or the like, a plurality of glasses images may be made comparable. Of course, when the number of glasses images 100 exceeds a predetermined number, etc., both the parallel display of the glasses images 100 and the switching of the display screen may be performed.

  In addition, in a present Example, although the structure which displays the spectacles image 100 comparably was mentioned as an example and demonstrated using the display 3 with which the spectacles mapping information acquisition apparatus 1 is equipped, it is not limited to this. For example, the glasses image 100 may be displayed comparably by using another device different from the glasses mapping information acquisition device 1 or a portable terminal (for example, a tablet terminal).

  Moreover, in the present embodiment, as a method of outputting a plurality of glasses images in parallel, the display on the display 3 has been described as an example, but the present invention is not limited to this. For example, when the method of outputting a plurality of glasses images in parallel is printing using a printer or the like, printing may be performed side by side on one sheet of paper.

  In addition, in a present Example, although the structure which displays two or more spectacles images 100 of left rim FRL of spectacles F on the comparison image 110 was mentioned as an example, and demonstrated, it is not limited to this. For example, the comparison image 110 may be configured to display a plurality of eyeglass images 100 of the right rim FRR of the eyeglasses F. Of course, the comparative image 110 may display both the glasses image 100 of the left rim FRL of the glasses F and the glasses image 100 of the right rim FRR of the glasses F.
