Regarding the sagging of the skin, studies on mechanical properties such as skin viscoelasticity and aging changes of the skin connective tissue have been reported as tactile changes due to the reduced function of the skin itself such as `` no elasticity, no firmness ''. ing. However, actually, the user feels sagging as a visual change such as “the eye corner goes down”, “mouth corner goes down”, and “cheek goes down”. Regarding these facial morphologies from a biological and morphological point of view, reports on the secular change of the facial appearance using the Moire method (Dent.

In two postures of sitting, which is a vertical position, the camera is always set in a direction parallel to the face, and the face and the scale placed on the face are simultaneously photographed. The horizontal position is a state of lying on the back of the bed, and the sitting position is a state of sitting on a chair, stretching the back, and putting the back of the head and the back on the wall. In addition, it is preferable to take a picture with the eyes closed when taking a picture, due to the influence of the line of sight.

る。As a method for calculating the amount of sagging of the skin, as shown in FIG. 2, the relative distance between each marked measuring point and the reference point is calculated using the image of the photographed photograph. The image analysis processing device calculates and calculates the relative distance value (L) of the vertical axis component of the median line connecting the chin and the chin.
Then, the relative distance value (L) of the component in the direction parallel to the midline of the face shown in FIG. 2 is lower in the sitting position in the horizontal position and in the sitting position due to gravity, as shown in FIG. Each relative distance value L 1 (horizontal position), L from the reference point in each posture
2 (sitting position) is measured and calculated, and the difference (L 2 −
The displacement position L 1 ) is defined as the amount of sagging of the skin. That is, the displacement of the sitting position with respect to the horizontal position is obtained as the amount of sagging of the skin.

For example, in the case of the face, when the reference point is set to the forehead, the root of the nose or under the eyes While there are parts such as the cheeks and chin where the displacement is in the positive direction, when the reference point is the nose root point, the displacement is in the negative direction in all parts. This indicates that the root of the nose is the least moved part of each part of the face, and the root of the nose is preferably used as a reference point when measuring the amount of sagging of the skin of the face in the present invention. The relative displacement of each measurement point from the root of the nose is defined as the amount of sagging of the skin.

る方法について、必ずしも上記方法に限定されない。Next, an example of measurement calculation of the relative distance value of the image of the face taken in by the imaging device (1) of FIG. 1 will be described with reference to FIG. As a first step, a conversion coefficient for converting the number of pixels into mm units is obtained based on a scale captured simultaneously with the face on the screen. As a second step, a vertical axis direction, which is a median line connecting the forehead and the chin, is designated, and its coordinates are obtained. As a third step,
The base point of the nose between the eyebrows, which is the reference point, is designated, and its coordinates are obtained. As a fourth step, the coordinates of the specified measurement point are obtained, and as a fifth step, the vertical direction on the photograph and the angle α of the deviation on the coordinate axis of the median line are obtained as shown in FIG. And the distance value A between the measurement point and the deviation angle β between the straight line connecting the measurement point and the reference point and the vertical direction on the photograph,
Next, the relative distance value L between the reference point and the measurement point is calculated by the following equation as an actual vertical component parallel to the midline. L = A × cos (β−α) Note that the above method is not necessarily used for measuring and calculating the relative distance value between the reference point and the measurement point as a relative rejection value L which is an actual vertical component parallel to the midline. It is not limited to.

Looking at the part difference between each part of the face, it became clear that the mouth parts i and h were the parts with the largest displacement, and the cheek g and the eye part b were also the parts with the largest displacement. In addition, the portions where the displacement was small were the cheek d, the eye side c, and the chin j. There was a difference in the displacement of each part due to the gravity load, and the mouth was the largest sagging part, and the line connecting the outer corner of the eyes and the mouth was the one where the sagging was observed.

からなる皮膚のたるみ量測定装置。1. An image of a distance between a reference point on the skin surface and each measurement point of a skin site where the amount of sag on the skin surface other than the reference point is to be measured. Imaging means for photographing the skin surface in two postures: a horizontal posture, and a vertical posture of the skin where the skin sags under the gravity load state; and inputting the photographed image described above; The distance between the above-mentioned reference point and each measurement point in two postures, a vertical position and a vertical position, is measured, and each measured distance is calculated as a relative distance value of a component in the vertical axis direction of the skin, which is a component in the gravity load direction. And an image analysis processing means for calculating the amount of displacement of the difference between the horizontal position and the vertical position of each relative distance value as the amount of slack in the skin.

るみ量として演算する皮膚のたるみ量測定方法。2. A distance between a reference point on the skin surface and each measurement point on the skin site where the amount of sag on the skin surface other than the reference point is to be measured, and the horizontal position of the skin in a supine position. The skin surface is photographed in two postures, that is, the posture of the skin surface and the posture of the vertical position of the skin where the skin sags under the gravity load state. The photographed image is input, and the horizontal position and the vertical position are input from the input image. The distance between the reference point and each measurement point in two postures is measured, and the measured distance is calculated as a relative distance value of a component in the vertical axis direction of the skin, which is a component in the direction of gravitational load. A method for measuring the amount of slack in the skin, which calculates the amount of displacement of the difference between the horizontal position and the vertical position of the distance value as the amount of slack in the skin.
