Description

  The present invention relates to a cosmetic determination system and a cosmetic determination program, and in particular, a cosmetic determination system and a cosmetic determination program capable of determining an optimal cosmetic.

  In general, women apply cosmetics on their faces to make their skin look better. Cosmetic products used at this time are preferred to have a natural finish as much as possible, and cosmetic manufacturers are developing various types of colors.

  A method often found to determine the color of a cosmetic product is one in which the salesperson looks at the color of the customer's face and determines the color that is more optimal for the salesperson's can.

  However, the method that relies on the salesperson's can has a problem that if the salesperson's can is bad, the optimal cosmetics cannot be selected and the customer's satisfaction may not be obtained.

  Therefore, a method for creating a skin color sample based on the color of the cosmetic product and selecting a cosmetic product having an optimum color compared to the created skin color sample and the face color is conceivable. For example, the leaflet with a skin color sample described in Patent Document 1 has a color close to the color of the skin of the face most by using the face skin exposed through a notch provided in a skin color sample based on the color of cosmetics. Used to select cosmetics as the optimal cosmetics.

  Further, there is a method for obtaining a regression line from the brightness before makeup and the brightness after makeup, and determining a cosmetic having a small difference from the brightness after makeup obtained by the regression line as an optimal cosmetic (patent) Reference 2).

  Thus, conventionally, the determination of the optimal cosmetic has been made with the highest emphasis on the skin color of the face.

However, if you choose the most appropriate cosmetics with the highest emphasis on the skin color of the face in this way, even if you make up with the selected cosmetics that you think is really the best, for example, if you look at the print that was completed by taking a picture, only the face May become strangely white and stunned. This is the so-called white floating phenomenon.

  Next, the operation of the cosmetic determination system controlled and realized by the cosmetic determination program of the present invention will be described in detail below.

  FIG. 3 is a diagram showing an example of a processing flow of the cosmetic determination system of FIG. 1 controlled by the cosmetic determination program of the present invention.

  In FIG. 3, when a process for determining cosmetics is started, counseling is performed by the makeup section determination processing section 103.

  The counseling is a process of asking a question for determining a makeup part, and the operator's state and intention can be grasped by this process. Specifically, in cooperation with the display control unit 107, a process of displaying the guidance screens shown in FIGS. 4 to 7 on the display device 400 and receiving information input in the input device 300 via the operation input unit 108. Is done.

  The counseling will be described with reference to FIGS. 4 to 7. First, in order to grasp whether or not the operator has already put on makeup, as shown in FIG. 4, a message 401 “What is makeup today?” "Yes" and "No" answer tags 402a and 402b indicating answers to the are displayed. On the other hand, based on the display, the operator makes an input for selecting the “Yes” answer tag 402a on the input device 300 when applying makeup, and “no” when not applying makeup. The input device 300 can perform input for selecting the answer tag 402b.

  When the “Yes” answer tag 402 a is selected on the screen of FIG. 4, the input is input to the computer 100 via the operation input unit 108, and the makeup unit determination processing unit 103 cooperates with the display control unit 107.

On the other hand, based on the display, the operator selects the “Yes” answer tag 402a when desiring to remove makeup, and selects the “No” answer tag 402b when desiring no makeup removal. Can do.

  When “Yes” is selected on the screen of FIG. 5, the input is input to the computer 100 via the operation input unit 108, and the makeup unit determination processing unit 103 cooperates with the display control unit 107. Display as shown in FIG. That is, a message 401 “Please remove makeup” shown in FIG. 6 is displayed. On the other hand, the operator may perform makeup removal.

  Further, after “None” is selected in the display of FIG. 4 or after “No” is displayed in the display of FIG. 5, the input is input to the computer 100 via the operation input unit 108, or FIG. After the display, the makeup part determination processing unit 103 cooperates with the display control unit 107 to display as shown in FIG. That is, “Yes” and “No” are displayed as the message 401 “Can I make makeup near the neck?” And the reply tags 402a and 402b shown in FIG. On the other hand, based on the display, the operator selects the “Yes” answer tag 402a if he wants makeup near the neck, and the “No” answer tag 402b if he does not want makeup near the neck. Can be selected. The input is input to the makeup determination processing unit 103 of the computer 100 via the operation input unit 108. By the process as described above, makeup part determination processing part 103 can grasp the state and intention of the operator.

  When the state and intention of the operator are grasped by the counseling, the makeup part determination processing unit 103 determines the makeup part based on the state and intention of the operator (S2).

  The makeup part is determined when makeup is applied to the face when the answer of “no” is given in the display of FIG. 4 and when “Yes” is answered in the display of FIG. If “Yes” is answered in the display of 7, it is determined that makeup is applied to the neck.

  Next, the makeup part determination processing unit 103 determines whether or not there is a makeup part determined in the process of S2 (S3).

  If it is determined that there is no makeup part, it is not necessary to determine cosmetics, so the process for determining cosmetics is terminated.

  Next, the operator's skin color is measured by the measuring device 200 (S4).

  The operator can measure the skin color of the measuring instrument 200 by, for example, prompting the display device 400 to measure the skin color in cooperation with the display control unit 107. The skin color measurement processing unit 104 controls the measuring device 200 via the measuring device input / output unit 106 to irradiate the measuring light, and measures the reflected light of the irradiated light. The measurement value of the reflected light is input to the skin color measurement processing unit 104 via the measuring instrument input / output unit 106. The measurement target part is a part of the operator's skin to be measured by the measuring instrument, and includes, for example, the cheek part 11 and the neck part 12 of the operator 10 as shown in FIG. The measurement site in S4 and the makeup part in S2 do not necessarily match. For example, even if only the neck is a makeup part, it may be necessary to measure a part where makeup is not performed, such as measuring the face and neck. For example, the skin color measurement processing unit 104 displays “Please measure the skin color of the cheek” on the display device 400 via the display control unit 107. It can be specified by using the measured value obtained by measuring as the measured value of the cheek.

  The skin color measurement processing unit 104 determines the skin color based on the input measurement value (S5).

The skin color is determined by L ^* a ^* b ^* color system brightness index L ^* , chromaticness index a ^* , b ^* , XYZ color system tristimulus values X, Y, Z, and The skin color of the measurement point is determined based on the value of any one of the hue H, lightness V, and saturation C of the Munsell color system. For example, when measuring the cheek and neck, the skin color obtained at the timing of measuring the cheek is set as the skin color of the cheek, and the skin color obtained at the timing of measuring the neck is determined as the skin color of the neck.

  Based on the skin color determined in S5, the cosmetic determination processing unit 105 determines a cosmetic (S6).

Cosmetics are determined by plotting the color of cosmetics prepared in advance in a three-dimensional color space, and when the skin color determined in S5 is plotted in the three-dimensional color space, the color space distance is the largest. Decided to make cosmetics smaller. When there are two measurement sites, the cosmetic color having the smallest color space distance is determined on a straight line connecting the two skin colors when the two skin colors are plotted. For example, as shown in FIG. 9 and FIG. 10, when cosmetics with colors 201a, 201b,... 201e are plotted in the L ^* a ^* b ^* color system, FIG. Values 202a and 202b obtained by measuring two parts of the neck are plotted. In FIG. 10, values 202c and 202d obtained by measuring the two parts of the face and the neck by an operator without makeup on the face are plotted. At this time, in FIG. 9, the distance between the straight line connecting 202a and 202b and the cosmetic of 201b having the smallest distance is determined. Similarly, in FIG. 10, the distance between the straight line connecting 202c and 202d is determined to be the cosmetic of 201e having the smallest distance.

  As described above, in the present invention, the color of cosmetics to be determined is plotted in advance in a three-dimensional color space, and the straight line determined by two measurement values in the three-dimensional color space and the color space are displayed. The cosmetic product with the smallest distance is determined as the optimal cosmetic product. That is, the present invention is characterized in that an optimal cosmetic is determined based on information of two measurement points.

  The cosmetic determined by the cosmetic determination processing unit 105 is notified to the operator (S7).

  The notification to the operator can be notified to the operator by, for example, controlling the display device 400 via the display control means 107 and displaying it by printing with a printing means (not shown).

  In the above aspect, the main control unit 101, the makeup unit determination processing unit 103, the skin color measurement processing unit 104, the cosmetic determination processing unit 105, and the display control unit 107 have been described as separate devices. A main storage device such as a ROM or a RAM that stores a program to be executed and an arithmetic device such as a CPU that performs arithmetic processing on the program can be integrated.

  Moreover, in the cosmetic determination system that implements the cosmetic determination program of the present invention, the processing of S1 to S3 in the description of the above processing flow is not an essential processing.

  Thus, the cosmetic determination system of the present invention acquires skin color information at a plurality of locations and determines the cosmetic based on the skin color information at the plurality of locations, so by performing makeup using the determined cosmetic, The finish after makeup is natural. In particular, it is possible to obtain a print that suppresses the phenomenon of whitening when taking a photograph.

  In the above aspect, the skin color is determined by directly measuring the skin color. However, the aspect in which the skin color is determined by photographing the measurement site of the operator under a predetermined photographing condition and measuring the printed matter is also photographed. This is preferable in order to exhibit the effect of eliminating the problem of whitening. At this time, it is more preferable to determine the color of the cosmetics plotted in the cosmetic determination process by measuring what is photographed and printed under the same photographing conditions.
