<Functional Blocks of Eyebrow Makeup Guide Device 10>
FIG. 2 is a diagram showing functional blocks of the eyebrow makeup guide device 10 according to one embodiment of the present invention. The eyebrow makeup guide device 10 can include an image acquisition unit 101 , a feature quantity calculation unit 102 , an eyebrow classification unit 103 and a presentation unit 104 . Further, the eyebrow makeup guide device 10 can function as an image acquisition unit 101, a feature amount calculation unit 102, an eyebrow classification unit 103, and a presentation unit 104 by executing programs. Each of these will be described below.

The image acquisition unit 101 acquires an image of the eyebrows. Specifically, the image acquiring unit 101 acquires an image of the eyebrows of the user 20 captured by the camera function of the eyebrow makeup guide device 10 or the like.

Note that the image in which the eyebrows are photographed may be an image in which the eyebrows and other than the eyebrows are photographed (for example, an image in which the entire face is photographed), or an image in which only the eyebrows are photographed (for example, the eyebrow makeup guide device 10 image captured so that the area of the eyebrows of the user 20 fits within a predetermined area displayed on the display device).

The feature quantity calculation unit 102 calculates the feature quantity of the eyebrows (details will be described later). Specifically, the feature amount calculation unit 102 calculates the feature amount of the eyebrows of the user 20 from the captured image of the eyebrows acquired by the image acquisition unit 101 .

The eyebrow classification unit 103 classifies eyebrows (for example, into categories indicating the shape of eyebrows such as straight eyebrows, upturned eyebrows, and downturned eyebrows) based on eyebrow feature amounts. Specifically, the eyebrow classification unit 103 classifies the eyebrows of the user 20 based on the eyebrow feature amount calculated by the feature amount calculation unit 102 .

The presentation unit 104 presents an eyebrow makeup guide for making the eyebrows into predetermined eyebrows based on the eyebrow classification results. Specifically, the presentation unit 104 presents an eyebrow makeup guide for making the eyebrows of the user 20 into predetermined eyebrows based on the eyebrow classification result by the eyebrow classification unit 103 (for example, the eyebrow makeup guide device 10 indicate. For example, the presentation unit 104 provides cosmetics and tools to be used to make the eyebrows of the user 20 into predetermined eyebrows, and drawing of eyebrows to make the eyebrows of the user 20 into predetermined eyebrows (in this specification , how the user 20 draws the eyebrows (referred to as "drawing"), the drawing area, the drawing order, the use of cosmetics and tools. Note that the predetermined eyebrows may be eyebrows selected from a plurality of eyebrows.

Here, I will explain the eyebrow makeup guide in detail. The eyebrow makeup guide includes cosmetics and tools to be used to make the eyebrows of the user 20 into the predetermined eyebrows, and the eyebrow drawing method, the drawing area, the drawing order, Including the use of cosmetics and tools.

For example, cosmetics and tools are eyebrow pencils, eyebrow powder, eyebrow mascara, brushes, combs, and the like.

For example, cosmetics and tools are determined according to the state of user's 20 natural eyebrows (user's 20 eyebrows before makeup) and predetermined eyebrows (that is, user's 20 desired eyebrows). For example, if a user 20 whose natural eyebrows are thin desires firm eyebrows, an eyebrow powder that changes the overall darkness is used. Also, for example, eyebrow powder is used when the original eyebrows are thin, eyebrow powder is used to balance the eyebrows when the eyebrows are thick but thick, and eyebrow pencil is used when the eyebrows are thick but sparse. is used, and eyebrow mascara, concealer, and eyebrow scissors may be used where the eyebrows are thick.

The method of drawing eyebrows, the drawing area, the order of drawing, the use of cosmetics and tools indicate the order in which areas to apply makeup and how to move the hands. For example, if your natural eyebrows are thin, draw them softly with eyebrow powder that blends well with your skin. Also, for example, if there is a difference between dark and thin eyebrows, the dark brown is added to the ungrown portion. Also, for example, if the natural eyebrows are dark, draw with an eyebrow pencil so as to fill the gaps. For sparse areas, finish by adding eyebrows one by one. Finally, use eyebrow mascara and apply it so that the hair flow is adjusted from the inner eyebrow to the outer eyebrow.

For example, the predetermined eyebrows are eyebrows selected by the user 20 or the like from a plurality of eyebrows. For example, the predetermined eyebrows may be eyebrows that match the image desired by the user 20 . Also, for example, the predetermined eyebrows are predetermined eyebrows. For example, the predetermined eyebrows may be trendy eyebrows selected by the eyebrow makeup guide device 10, "basic eyebrows", "eyebrows with desired impression (cute, fresh, cool, elegant, etc.) (feature map ( (from the four quadrants of a map classifying features)," desired eyebrows (neat eyebrows, soft eyebrows, parallel eyebrows, etc.)", and "eyebrows matching the scene", or determined from the facial features of the user 20 It may be a sculpted eyebrow.

For example, when the eyebrows of the user 20 are raised eyebrows and the user 20 wants the eyebrows to have a gentle impression (when the image desired by the user 20 is a "gentle impression"), an eyebrow powder that gives a gentle and soft impression is applied to the upper part of the eyebrow tip and the eyebrow peak. Draw the lower part of the , and make the angle of the eyebrows gentle. Draw the peak of the eyebrow gently without making it too sharp, and gradually taper the tail of the eyebrow. If there are sparse parts, draw to fill in the gaps. Finally, gently blur with a screw brush so that the inner corners of the eyebrows do not become strong.

For example, when the eyebrows of the user 20 are lowered and the user 20 wants to have a proper eyebrow (when the image desired by the user 20 is a "precise impression"), an eyebrow pencil that gives a proper feeling is used to adjust the position of the eyebrow. Take it slightly higher and draw from the peak of the eyebrow to the end of the eyebrow so that it gradually becomes thinner. Next, draw the part from Mt. Bizan to the inner part of the eyebrow. Finally, add a darker shade to the center of the eyebrows to give it a three-dimensional look.

<Processing method>

In step 12 (S12), the feature amount calculation unit 102 reduces the number of gradations of the image of the eyebrow region extracted in S11 (for example, binarizes). For example, the feature amount calculation unit 102 uses at least one of luminance, lightness, RGB Blue, and RGB Green to reduce the number of gradations of the image of the eyebrow region. Note that S12 may be omitted.

In step 13 (S13), the feature amount calculation unit 102 extracts the amount of change in the pixel value of the image of the eyebrow region extracted in S11 (the image with the number of gradations lowered when S12 is executed). do. Specifically, the feature amount calculation unit 102 extracts changes in pixel values in a certain direction (changes in pixel values in at least one direction from the top to the bottom of the eyebrow and from the head to the tail of the eyebrow). do.

At step 14 (S14), the feature quantity calculation unit 102 calculates the feature quantity of the eyebrows based on the amount of change in the pixel value extracted at S13. For example, the feature amount calculation unit 102 calculates feature amounts of eyebrow shape and eyebrow density.

<Eyebrow feature amount>
The feature amount of eyebrows will be described below. For example, the eyebrow feature amount indicates the shape and density of the eyebrow.
