Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a spectacle lens shape design selection method and apparatus in which an operator selects a spectacle lens shape design by an interactive method using means including a computer-controlled display screen.
[0002]
[Prior art]
Conventionally, a computer graphics technique or the like is used to capture a spectacle wearer's portrait (facial image) into a computer, analyze the features of the facial features according to a predetermined procedure, and determine the analysis results in advance. A method of designing a spectacle shape by applying to the designed design rules has been proposed (see, for example, Japanese Patent Laid-Open Nos. 5-35827 and 7-168875).
[0003]
The above-mentioned conventional method is characterized by the spectacle wearer's facial features compared to the conventional method in which the design of the spectacles tends to be determined without considering the difference in spectacle wearer's facial features. Since computer analysis is performed, it is possible to increase the possibility of obtaining eyeglass designs that match the facial features.
[0004]
[Problems to be solved by the invention]
By the way, in the above-described method, a computer mainly performs a procedure for analyzing a feature of a facial feature and selecting a design that matches the feature. In other words, in this method, it is the system software creator, such as a designer or programmer, that ultimately determines the feature analysis of facial features and the design that fits the analyzed features. . Therefore, it is inevitable that the resulting design will depend greatly on the sensitivity and way of thinking of the system software creator.
[0005]
However, design preferences vary from person to person, and it is rather difficult to imagine that a particular designer's sensibility is accepted by everyone. Therefore, the above-described conventional method can provide a satisfactory result when the designer's sensibility or the like acts in a good direction, but at the same time, the reverse case may occur. Moreover, since all the main procedures are determined by the computer, there is little room for the operator to select.
[0006]
In consideration of the above circumstances, the present invention allows the operator to select a lens shape design close to the image desired by the operator from among a large number of samples by inputting a keyword imaged by the operator. An object of the present invention is to provide an apparatus for selecting a target lens shape design.
[0007]
[Means for Solving the Problems]
The invention of claim 1 is a method in which an operator selects the eyeglass design of glasses by an interactive method using means including a computer-controlled display screen.
A large number of target lens design data is stored, and each target lens design data is assigned with one or more keywords for classification.
According to the display screen, a keyword intended by an operator is input to search the database, and target lens shape design data including the keyword is extracted.
The invention of claim 2 is an apparatus in which an operator selects a lens shape design of glasses by an interactive method using means including a computer-controlled display screen, and stores a large number of lens shape design data, A database in which one or more keywords for classification are assigned to the mold design data, a keyword input means for inputting the keyword intended by the operator according to the display screen, and a database search in response to the keyword input And a search means for extracting target lens shape design data including a keyword.
[0008]
The invention of claim 3 is characterized in that, in claim 2, the search means extracts the lens shape design data corresponding to the intersection set of keywords when a plurality of keywords are inputted.
[0009]
According to a fourth aspect of the present invention, in the second or third aspect, there is at least two keywords assigned to each of the target lens shape design data, and one of the keywords is preliminarily classified among a plurality of groups. It belongs to a group, and another one keyword belongs to the 2nd group different from the 1st group, It is characterized by the above-mentioned.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
The target lens design selection apparatus 1 according to the embodiment is an apparatus in which an operator selects a target lens shape design by an interactive method using means including a computer-controlled display screen. As shown in FIG. And a computing device (corresponding to search means) 3 which is a computer main body, a display 4 for screen display, and an input device 5 (corresponding to keyword input means) such as a keyboard and pointing device.
[0011]
The database 2 stores a large number (for example, 100 to 200 or more) of target lens shape design data, and two or more keywords for classification are assigned to each data. The keywords are broadly divided into two large groups having different systems, and at least one keyword (three in this example) belonging to each large group is attached to one data.
[0012]
The first large group is a group of keywords that are named based on general consumer sensibility (keywords for general selection). Under the items of the first large group, there are three small groups. Group items are provided in parallel, and a plurality of keywords are provided in parallel under each small group item, forming a tree structure as a whole. The second large group is a group of keywords (keywords for technical selection) that are named based on the thoughts of experts, and there are three small groups under the items of the second large group. Items are provided in parallel, and a plurality of keywords are provided in parallel under the items of each small group, forming a tree structure as a whole.
[0013]
The specific classification method of the keywords in the first large group for “general selection” is as follows. As small items, three small groups of (1) fashion image, (2) shape, and (3) type are provided, and the following keywords are assigned to each small group.
[0014]
(1) Fashion image, formal business, casual sport [0015]
(2) Shape, circle, ellipse (round, oval)
・ Square (Wellington)
・ Rectangle (square)
・ Triangle (Teardrop, Boston)
・ Others [0016]
(3) Type Men's Women's Unisex [0017]
The specific classification method of the keywords in the second large group for “technical selection” is as follows. As small items, three small groups of (1) aspiration, (2) face type, and (3) function are provided, and the following keywords are assigned to each small group.
[0018]
(1) Desire ・ I want to show it intellectually ・ I want to show it thinly ・ I want to show it elegantly ・ I want to show it gently ・ I want to show it cheerfully ・ I want to show it cutely [0019]
(2) Face type, round face orientation, large face orientation, small face orientation, long face orientation [0020]
(3) Function / Strength lens orientation / Progressive lens orientation / Medium / Near lens orientation / Near vision lens orientation / Lightening shape
The relationship between each lens shape design and keywords is determined based on the opinions of general consumers with no specialized knowledge for the first large group. The second large group is decided based on the opinions of experts such as designers and spectacle advisors. For example, when deciding on a "fashion image" for a certain target lens design, present the target lens shape, and feel the fashion image you see by looking at the target lens. Formal, business, casual, sports For the four factors, the score is 10 points in total. Then, the factor having the highest point is determined as a keyword of the item of fashion image, and the keyword is attached to the data of the corresponding target lens design.
[0022]
As described above, keywords are assigned to each item in a distributed manner, so that one target lens shape design data stored in the database 2 is assigned three keywords in two groups.
[0023]
When these keywords are input by the input device 5, the arithmetic device 3 accesses the database 2 and executes a search, and extracts all target lens design data including the corresponding keywords. In this case, since a maximum of three keywords are input, the target lens shape design data corresponding to the intersection set of keywords is extracted and displayed on the display 4.
[0024]
Next, a series of operations and actions will be described.
2 and 3 show a screen 10 displayed on the display 4.
Select "General selection" or "Technical selection" on the initial screen. When “general selection” is selected, the screen 10A shown in FIG. 2 is displayed. When “technical selection” is selected, the screen 10B shown in FIG. 3 is displayed. When changing from the screen 10A in FIG. 2 to the screen 10B in FIG. 3 or vice versa, the selection key 11 is clicked.
[0025]
As shown in FIG. 2, in the “general selection” screen 10A, the menus of keywords 12a to 13a to 14a are displayed for the three items of the fashion image 12, the shape 13, and the type 14, respectively. Move the pointer to select one of the keywords. If the selected content is OK, the “OK key” 16 is clicked. Then, the search is started. When the search result is obtained, the target lens design is displayed on the portrait 20 of the screen 10A. In order to cancel the selected content, the “cancel key” 17 may be clicked.
[0026]
Similarly, as shown in FIG. 3, on the “technical selection” screen 10B, menus of keywords 22a to 23a to 24a are displayed for the three items of the desire 22, the face type 23, and the function 24, respectively. Therefore, any keyword is selected by matching the pointer. If the selected content is OK, the “OK key” 16 is clicked. Then, the search is started, and when the search result is obtained, the target lens design is displayed on the portrait 20 of the screen 10A.
[0027]
In this way, by simply inputting a keyword while viewing the screens 10A and 10B, it is possible to immediately extract a target lens design close to the desired image and display it on the display screen. Therefore, the operator can easily select a target lens design that matches the image he / she desires.
Also, as a method of using this device, in addition to simply using it as a stand-alone type lens shape design selection device, for example, it can be incorporated into various devices such as a spectacle simulation device, an optometry device, or a system such as a spectacle custom-made system. It can be used by connecting and forming a network.
[0028]
【The invention's effect】
As described above, according to the present invention, a lot of target lens design data with keywords is stored in the database, and it is close to the image of the operator without performing complicated shape changes or the like. Easy to select the target design. Therefore, when keywords are added to each target lens design, if opinions and ideas are broadly reflected, it is free to meet the preferences of specific people such as designers and programmers. You can choose a different design.
