Description

  The present invention relates to a technique for measuring height-related information such as the height or height of an organ of a human body, and in particular, calculates the height of an organ from an image of the measured person or the height of the measured person from the calculated height of the organ. The present invention relates to a technique for estimating body height, and a body component analysis technique that enables body component analysis without requiring input of user information such as the gender and age of a measurement subject.

  The method of measuring height is large and can be classified into a contact type and a non-contact type. The contact-type height measurement method is a method of measuring the height by contacting a physical device with the human body.For example, the bar is placed on the head of the subject manually or automatically with the subject standing upright. Measure height by measuring the distance between the sole of the foot and the lower position of the bar.

  The non-contact type height measurement method is a method for measuring the height of a physical device without touching the human body. For example, an ultrasonic sensor that grasps the height while the person being measured stands upright. The ultrasonic sensor is used to emit ultrasonic waves to the measurement subject's head, detect the ultrasonic waves reflected from the measurement subject's head, and calculate the distance between the measurement subject's head and the ultrasonic sensor. The height of the person to be measured can be measured by subtracting the calculated distance from the height.

  However, the contact-type height measurement method may cause discomfort because the physical device is in contact with the human body, and the non-contact type height measurement method using ultrasonic waves is precise because the ultrasonic waves are reflected by the hair. Therefore, there is an inconvenience that an ultrasonic sensor must be provided at a position higher than the height of the person being measured.

  Therefore, the present inventor conducted research on a technique capable of obtaining the measurement subject's height-related information more precisely than the non-contact method without causing discomfort without contacting a physical device. .

  In addition, the conventional body component analysis apparatus requires user information such as the gender and age of the person to be measured in order to analyze the body component of the person to be measured.

  Therefore, the present inventor has conducted research on body component analysis technology that can improve user convenience by being able to analyze body components without requiring input of user information such as the gender and age of the subject. .

  Hereinafter, the present invention will be described in detail so that those skilled in the art can easily understand and implement the present invention through preferred embodiments described with reference to the accompanying drawings.

  In the description of the present invention, when it is determined that a specific description for a known function or configuration related to the present invention obscures the gist of the embodiment of the present invention, the detailed description thereof is omitted.

  The terms used throughout the specification of the present invention are terms that are defined in consideration of the functions in the embodiments of the present invention, and can be sufficiently modified according to the intentions, practices, etc. of users or operators. The definition of this term should be made based on the contents throughout this specification.

  FIG. 1 is a perspective view showing a configuration of an embodiment of a height related information measuring apparatus according to the present invention, and FIG. 2 is a block diagram showing a configuration of an embodiment of the height related information measuring apparatus according to the present invention.

  As shown in FIGS. 1 and 2, the height related information measuring apparatus 100 according to this embodiment includes a position restriction unit 110, a camera unit 120, a height related information calculation unit 130, and a height related information output unit 140. .

  The position restriction unit 110 restricts the measurement position of the measurement subject. Here, you may implement | achieve so that the position limitation part 110 may limit the position where a to-be-measured person steps on. For example, as shown in FIG. 1, a lower body 10 is configured, and a position restricting portion 110 in the shape of a person's sole is formed on the lower body, so that a person to be measured becomes a position restricting portion 110 in the shape of a person's sole. The position to step on can be limited by standing.

  The camera unit 120 captures an image of the measurement subject whose position is limited by the position limiting unit 110. For example, the upper body 30 is coupled to the upper stage of the support unit 20 coupled to the front surface of the lower body 10, and the camera unit 120 is provided on the upper body 30 so that the camera unit 120 can be fixed, rotated, or movable. It may be realized that the camera unit 120 captures an image of the measurement subject in a state of staring.

  Here, when the person to be measured stands on the position restriction unit 110 in the shape of the sole of the person formed on the lower body 10, the position of the person to be measured is restricted, and in this state, the camera unit 120 displays the image of the person to be measured. When the image is taken, an image of the subject whose position is restricted is taken.

  The height-related information calculation unit 130 may be realized in the form of a microprocessor mounted on the upper body 30 or software executed thereby, and the specific organ is identified from the image of the measurement subject taken by the camera unit 120. Recognize and calculate the height related information of the subject under measurement based on the recognized organ. The height-related information may be an organ height calculation value or a height estimation value.

  Here, the height related information calculation unit 130 may calculate the recognized organ height, and the height of the measured person may be estimated based on the calculated organ height. For example, the height-related information calculation unit 130 can estimate the height of the measurement subject by adding up the camera height, the calculated organ height, and the estimated value estimated from the organ height.

  Here, for more precise measurement, the height-related information calculation unit 130 calculates the organ height by reflecting the horizontal distance between the camera unit 120 and the position restriction unit 110 when calculating the organ height. It may be realized. The horizontal distance between the camera unit 120 and the position limiting unit 110 may be a preset value normalized in advance, or may be a value acquired in real time by a distance detection sensor (not shown) or the like.

  FIG. 3 is a schematic diagram of height measurement of the height related information measuring apparatus according to the present invention. In FIG. 3, H is the height of the subject to be measured, h1 is the height of the camera, h2 is the height of the organ calculated from the video of the subject, and h3 is an estimated value estimated from the height of the organ. , D is assumed to be a horizontal distance between the camera unit 120 and the position limiting unit 110.

  The camera height h1 is preliminarily set to a fixed setting value when the camera unit 120 is fixed, and a setting value that varies according to the up / down movement distance when the camera unit 120 is movable in the up / down direction. This is the value that has been determined.

  The organ height h2 calculated from the measurement subject image is, for example, the central position of the organ recognized in the entire image captured by the camera from the reference y coordinate in the entire image region captured by the camera. It may be calculated according to the number of pixels between the y coordinates.

  Here, the height per pixel changes according to the horizontal distance d between the camera unit 120 and the position limiting unit 110, and the horizontal distance d between the camera unit 120 and the position limiting unit 110 is kept constant. By limiting the position of the person to be measured, the height per pixel can be normalized and the organ height h2 can be accurately calculated.

  The reference y-coordinate of the entire video area photographed by the camera is a value that changes depending on the tilt angle of the camera. When the camera is provided so as to face the front accurately, the reference y-coordinate is photographed by the camera. Y coordinate at the center of the entire video area.

  On the other hand, since an organ like the human eye is proportional to the height, the estimated value h3 estimated from the height of the organ is analyzed empirically by analyzing the relationship between the specific organ and the height from people of a plurality of sample groups. Or it can be normalized experimentally.

  Since the estimated value h3 estimated from the camera height h1 and the organ height is a predetermined value, the height related information calculation unit 130 calculates only the organ height h2 calculated from the measurement subject image. When calculated, the height H = h1 + h2 + h3 of the measurement subject can be calculated.

  For example, after the height-related information calculation unit 130 detects a feature point of a specific organ such as the eye from the entire image captured by the camera, recognizes the specific organ, and calculates the y coordinate of the center position of the recognized organ. The number of pixels between the y-coordinates of the central position of the organ recognized in the entire image captured by the camera is calculated from the reference y-coordinate in the entire image area captured by the camera, and the calculated pixel number The organ height h2 is calculated. In addition, this calculates the height H = h1 + h2 + h3 of the person to be measured.

  The height related information output unit 140 outputs the height related information calculated by the height related information calculation unit 130. Here, the height-related information output unit 140 may be configured to output the height-related information on the screen, output the sound, output the network, or output the print.

  For example, the height-related information output unit 140 may be realized in the form of an LCD panel formed on the front surface of the upper body 30, and the height-related information calculated by the height-related information calculation unit 130 may be output on the screen. .

  Therefore, the present invention described above recognizes a specific organ from the image of the person being measured, and calculates the height related information of the person to be measured based on the recognized organ, so that the physical device does not touch the human body. Without feeling uncomfortable, accurate height-related information can be acquired by estimating the height-related information of the measurement subject by organ recognition.

  According to an additional embodiment of the present invention, the height-related information measuring apparatus 100 may further include a rotation driving unit 150 that automatically or manually changes the shooting angle of the camera. Here, as shown in FIG. 4, the rotation driving unit 150 may drive the camera unit 120 in the up / down direction to change the shooting angle.

  In contrast to this, as shown in FIG. 5, the rotation driving unit 150 rotates the height-related information output unit 140 fixed to the camera unit 120 in the up / down direction to change the shooting angle. Also good.

  That is, in the embodiment shown in FIG. 4, the rotation drive unit 150 is configured to rotate the camera unit 120 itself in the upward / downward direction, so that the embodiment shown in FIG. By configuring the rotational drive unit 150 to rotationally drive the related information output unit 140 in the up / down direction, the measurement subject can be freely changed up / down according to the height of the measurement subject. It is possible to recognize specific organs by shooting the video.

  According to an additional embodiment of the present invention, as shown in FIG. 6, the height-related information measuring apparatus 100 may further include a linear driving unit 160 that automatically or manually changes the shooting position of the camera. The linear driving unit 160 linearly drives the camera unit 120 in the up / down direction to change the shooting position.

  That is, in the embodiment shown in FIG. 6, the linear drive unit 160 is configured to linearly drive the camera unit 120 in the up / down direction, so that the position of the camera can freely move up / down according to the height of the person to be measured. A specific organ can be recognized by capturing an image of the subject while moving.

  According to an additional embodiment of the present invention, as shown in FIG. 7, the camera unit 120 of the height related information measuring apparatus 100 may include a plurality of cameras spaced apart in the up / down direction.

  That is, in the embodiment shown in FIG. 7, the camera unit 120 is configured to select a suitable one of a plurality of cameras provided apart in the upward / downward direction and capture a video of the measurement subject. Thus, an appropriate camera can be selected according to the height of the person being measured, and a video of the person being measured can be taken to recognize the specific organ.

  According to an additional embodiment of the present invention, as shown in FIG. 8, the height-related information measuring apparatus 100 may further include a polarizing lens 170 that expands a shooting angle on the front surface of the camera unit 120.

  In this embodiment, a polarizing lens 170 that expands the photographing angle is provided on the front surface of the camera unit 120 to further enlarge the image area of the measurement subject photographed by the camera unit 120 at a close distance.

  The camera unit 120 of the height-related information measuring apparatus 100 according to the present invention may use a general-type camera in which optical systems (a plurality of lenses) are arranged in a line. As shown in FIG. You may use the camera of the scanning system of the form (lens and mirror) disperse | distributed.

  The camera unit 120 shown in FIG. 9 includes a light output unit 121, a spherical lens 122, a rotating mirror 123, and a light detection unit 124. The light output unit 121 outputs light. The spherical lens 122 refracts and collects the light output from the light output unit 121.

  The rotating mirror 123 reflects the light refracted and collected by the spherical lens 122 and makes it incident on the subject, and reflects the light reflected from the subject and makes it incident on the spherical lens. The light detection unit 124 detects light reflected by the rotating mirror 123 and refracted and collected by the spherical lens 122.

  In other words, in this embodiment, an image of the person to be measured can be taken using a scan-type camera in which optical systems (lenses and mirrors) are dispersed.

  According to the additional embodiment of the present invention, the weight related information measuring apparatus 100 measures the weight of the person to be measured, and the weight information output unit 190 outputs the information related to the weight measured by the weight measuring unit 180. May be further provided.

  For example, when the weight measuring unit 180 is provided on the lower body 10 illustrated in FIG. 1 and the person to be measured stands on the position restriction unit 110 in the shape of the sole of the person formed on the lower body 10, the weight measuring unit 180 is You may implement | achieve measuring a to-be-measured person's weight.

  On the other hand, the weight information output unit 190 that outputs information about the weight of the person to be measured may be realized in a separate device from the height-related information output unit 140 that outputs the height-related information of the person to be measured. The weight information output unit 190 and the height related information output unit 140 may be realized in the same device.

  That is, in this embodiment, the height of the person being measured can be measured simultaneously with the height related information measuring apparatus 100 according to the present invention, and the weight can also be measured.

  According to an additional embodiment of the present invention, the height related information measuring apparatus 100 may further include an activation signal input unit 200 that receives an input of an activation signal for starting measurement of information related to the measurement subject's height.

  Here, the activation signal input unit 200 may receive an input of an activation signal for starting measurement by a special key operation. However, the activation signal may be input by voice input or action input method that does not require key operation for precise measurement. It may be realized so that.

  For example, it is realized that the activation signal input unit 200 reads the measurement subject's voice and detects the activation signal, and starts measurement by detecting the measurement subject's voice input such as “measurement start”. It may be realized.

  That is, the height related information measuring apparatus 100 according to the present invention limits the position of the person being measured by the position limiting unit 110 for precise measurement. If the user performs a special key operation to start measurement, it is not only cumbersome, but there is a risk of affecting the precision measurement depending on the movement of the person being measured due to the key operation. Therefore, in order to start measurement without performing a special key operation, the activation signal may be input by voice input or action input method.

  On the other hand, according to an additional embodiment of the present invention, the measurement target person image captured by the camera unit 120 has different actual distances for each pixel depending on the tilt angle of the camera unit, and thus correction thereof is necessary. is there.

  If the camera unit 120 is fixedly provided in an inclined state, an aspheric lens (not shown) is provided in front of the lens of the camera unit to correct the image of the measurement subject photographed by the camera unit 120. May be.

  If the camera unit 120 is provided so as to be rotatable up / down, the measurement subject image captured by the camera unit 120 may be corrected by software according to the tilt angle of the camera unit 120. Therefore, accurate image information related to height can be obtained by such image correction.

  FIG. 10 is a perspective view showing a configuration of an embodiment of a body component analyzer according to the present invention, and FIG. 11 is a block diagram showing a configuration of an embodiment of a body component analyzer according to the present invention.

  As shown in FIGS. 10 and 11, the body component analyzer 1100 according to this embodiment calculates the bioimpedance of the measurement subject by measuring the voltage applied to the body of the measurement subject. A device for analyzing a body component of a person to be measured from bioelectrical impedance, and includes a camera unit 1110 and a height related information calculation unit 1120.

  The camera unit 1110 captures an image of the measurement subject. As shown in FIG. 10, an upper body 1030 is coupled to an upper stage of a support portion 1020 coupled to the front surface of the lower body 1010, and a camera unit 1110 is provided on the upper body 1030 so as to be fixed, rotated, or movable. May be realized such that the camera unit 1110 shoots an image of the person being measured while staring at the camera unit 1110.

  The height-related information calculation unit 1120 may be realized in the form of a microprocessor mounted on the upper body 1030 or software executed thereby, and the specific organ is identified from the video of the measurement subject captured by the camera unit 1110. Recognize and calculate the height related information of the subject under measurement based on the recognized organ. The height-related information may be an organ height calculation value or a height estimation value.

  Here, the height-related information calculation unit 1120 may calculate the recognized organ height, and the height of the measured person may be estimated based on the calculated organ height. For example, the height-related information calculation unit 1120 can estimate the height of the measurement subject by adding the camera height, the calculated organ height, and the estimated value estimated from the organ height.

  Here, for more precise measurement, the height-related information calculation unit 1120 calculates the organ height by reflecting the horizontal distance between the camera unit 1110 and the measurement subject when calculating the organ height. It may be realized. The horizontal distance between the camera unit 1110 and the person to be measured may be a preset value normalized in advance or may be a value acquired in real time.

  On the other hand, according to an additional embodiment of the present invention, the body component analyzer 1100 according to the present invention uses a position restriction unit 1130 as shown in FIG. Further, it may be provided. The position restriction unit 1130 restricts the measurement position of the person to be measured and makes the horizontal distance between the camera unit 1110 and the person to be measured constant.

  Here, the position limiting unit 1130 may be a foot electrode. For example, by forming a foot electrode in the shape of a human foot on the lower body 1010 so that the measured person stands on the foot electrode in the shape of a human foot, the measurement position of the measured person is limited. Also good.

  On the other hand, according to an additional embodiment of the present invention, in order to acquire the horizontal distance between the person to be measured in real time, the body component analyzer 1100 according to the present invention includes a distance detection sensor as shown in FIG. 1140 may further be provided. The distance detection sensor 1140 measures the horizontal distance between the camera unit 1110 and the person to be measured.

  FIG. 14 is a schematic diagram of height measurement of the body component analyzer according to the present invention. In FIG. 14, H is the height of the person to be measured, h1 is the height of the camera, h2 is the height of the organ calculated from the video of the person to be measured, and h3 is an estimated value estimated from the height of the organ. , D is assumed to be a horizontal distance between the camera unit 110 and the person to be measured.

  The camera height h1 is preliminarily set to a setting value that is fixed when the camera unit 1110 is fixed, and a setting value that varies depending on the upward / downward movement distance when the camera unit 1110 is movable in the up / down direction. This is the value that has been determined.

  The organ height h2 calculated from the measurement subject image is, for example, the central position of the organ recognized in the entire image captured by the camera from the reference y coordinate in the entire image region captured by the camera. It may be calculated according to the number of pixels between the y coordinates.

  Here, the height per pixel changes according to the horizontal distance d between the camera unit 1110 and the person to be measured, and the horizontal distance d between the camera unit 1110 and the person to be measured is kept constant. By limiting the position of the person to be measured, the height per pixel can be normalized and the organ height h2 can be accurately calculated. The position limitation of the measurement subject will be specifically described later.

  The reference y-coordinate of the entire video area photographed by the camera is a value that varies depending on the tilt angle of the camera. When the camera is provided so as to face the front accurately, the reference y-coordinate is photographed by the camera. This is the y-coordinate that is the center of the entire video area.

  On the other hand, since an organ like the human eye is proportional to the height, the estimated value h3 estimated from the height of the organ is analyzed empirically by analyzing the relationship between the specific organ and the height from people of a plurality of sample groups. Or it can be normalized experimentally.

  Since the estimated value h3 estimated from the camera height h1 and the organ height is a predetermined value, the height-related information calculation unit 1120 calculates only the organ height h2 calculated from the measurement subject image. When calculated, the height H = h1 + h2 + h3 of the measurement subject can be calculated.

  For example, after the height-related information calculation unit 1120 detects a feature point of a specific organ such as the eye from the entire image captured by the camera, recognizes the specific organ, and calculates the y coordinate of the center position of the recognized organ. The number of pixels between the y-coordinates of the central position of the organ recognized in the entire image captured by the camera is calculated from the reference y-coordinate in the entire image area captured by the camera, and the calculated pixel number The organ height h2 is calculated. Further, the height H = h1 + h2 + h3 of the person to be measured is calculated from this.

  Therefore, the above-described present invention recognizes a specific organ from the image of the subject and calculates the height-related information of the subject to be measured based on the recognized organ, so that the physical device does not contact the human body. Therefore, accurate height-related information can be acquired by estimating the height-related information of the measurement subject by organ recognition without feeling uncomfortable.

  According to an additional embodiment of the present invention, a body component analysis apparatus 1100 according to the present invention includes a pair of foot electrode bodies 1150, a hand electrode body 1160, a switching unit 1170, a measurement unit 1180, and a body component analysis unit 1190. Become.

  The pair of foot electrode body 1150 and hand electrode body 1160 includes at least one current application electrode 1151 and 1161, and at least one voltage measurement electrode 1152 and 1162, respectively.

  The switching unit 1170 performs connection or disconnection between the current application electrodes 1151 and 1161 included in each foot electrode body 1150 and the hand electrode body 1160 according to the measurement site, and simultaneously each foot electrode body 1150 and the hand electrode. Connection or disconnection between the voltage measuring electrodes 1152 and 1162 included in the body 1160 is performed.

  The measurement unit 1180 applies a current to the body part of the measurement subject that is in contact with the current application electrodes 1151 and 1161 connected by the switching unit 1170, and contacts the voltage measurement electrodes 1152 and 1162 connected by the switching unit 1170. The voltage is measured at the body part of the measured subject.

  The body component analysis unit 1190 calculates the bioimpedance for each body part of the measurement subject from the voltage measured by the measurement unit 1180, and the body component of the measurement subject from the calculated bioimpedance for each body part of the measurement subject Analyze.

  Here, the body component analysis unit 1190 reflects the height related information calculated by the height related information calculation unit 1120 when analyzing the body components of the measurement subject. The information related to the height of the person being measured at the time of analysis of the body component is a main variable. For example, a value obtained by dividing the square of the height by the bioelectrical impedance is used as an impedance index, and this impedance index is related to the muscle mass of the body.

  Therefore, if the height-related information of the measured person is automatically calculated and reflected in the analysis of the body component of the measured person, the measured person does not need to input user information such as age and sex of the measured person separately. Therefore, the convenience of the user can be improved.

  FIG. 15 is a schematic diagram of body component analysis measurement of the body component analyzer according to the present invention. FIG. 15 shows an electrical model of the human body for analyzing body components for each part of the subject. The electrical model of the human body shown in FIG. 15 does not assume that the human body is a conductor having one human body resistance, but has conductors each having five human body resistances: right arm, left arm, torso, right foot, and left foot. Is assumed.

As shown in the figure, the resistance for each region is represented by R _RA , R _LA , R _T , R _RL , R _LL . Resistors R ₁ and R ₂ represent the resistance of the thumb and palm and extend outwardly from the wrist site in the form of a branch. The resistances R ₃ and R ₄ represent the resistance of the heel and the sole of the foot, and form a branch from the ankle region and extend outward.

  For measurement, the person to be measured steps on the foot electrodes E5, E6, E7, E8 and holds the hand electrodes E1, E2, E3, E4. The body components are automatically analyzed for each part and the results are output.

Referring to a method of measuring the different parts of the human body resistance, for example, to measure the human body resistance R _RA right arm electric current between the hands electrode E1 and feet electrodes E5 through the switching operation of the switching unit 1170, measuring The unit 1180 measures a voltage between the hand electrode E2 and the hand electrode E4. The current flows through R ₁ → R _RA → R _T → R _RL −R ₃ , and the voltage is measured in a loop formed by R ₂ → R _RA → R _LA → R ₂ . The measured loop current flow passages and the voltage measures the human body resistance R _RA right arm overlap with R _RA. When the input impedance of the voltage measurement terminal of the body component analyzer is large due to such measurement, the human resistance value at the end applied to R _{1 to} R ₄ does not affect the measurement of the right arm resistance. This means that even if the contact resistance is changed and the resistance values of R _{1 to} R ₄ are changed, the resistance value for each part of the human body is not affected.

The bioimpedance of the other part on the right side is measured similarly to the measurement of the right arm. When a current is passed between the hand electrode E1 and the foot electrode E5 and a voltage is measured between the hand electrode E4 and the foot electrode E8, the human body resistance _{RT of the} torso is reduced between the foot electrode E6 and the foot electrode E8. Is measured, the human resistance _RRL of the right foot can be obtained. In order to obtain the bioelectrical impedance for each part on the left side, when a current is passed between the hand electrode E3 and the foot electrode E7 and the voltage is measured between the hand electrode E2 and the hand electrode E4, the human body resistance R _LA of the left arm is obtained. When the voltage is measured between the foot electrode E6 and the foot electrode E8, the human body resistance _RLL of the left foot can be obtained.

  When the human body resistance is obtained by the measurement unit 1180, the body component analysis unit 190 analyzes the body component of the person to be measured from the human body resistance using a bioelectrical impedance measurement (BIA) technique.

  The bioimpedance measurement technique is a technique for measuring body moisture of a human body using an electrical method. When a weak alternating current signal is passed through the human body, it flows along the highly conductive body moisture. The amount of moisture will determine the width of the flow path, which is represented by a measured value called impedance.

The impedance Z is a force that disturbs electricity when it flows. The impedance is engineeringly determined as a vector sum of the resistance R and the reactance _Xc .

  However, in the case of the human body, the impedance and resistance values differ only by about 2 to 3Ω, and these differences are so small that they can be ignored. Therefore, in the bioimpedance measurement field, the impedance is considered to be the same as the resistance value.

  The resistance R of the conductor is proportional to the specific resistance ρ and the length L of the conductor, and inversely proportional to the cross-sectional area A.

  From the above equation, the volume V of the conductor may be expressed as a function of the specific resistance ρ, the length L of the conductor, and the resistance R.

  When this equation is applied to the human body, the volume V of the conductor corresponds to the body moisture of the human body, the specific resistance ρ corresponds to the resistance C per unit volume of body moisture, the length L of the conductor corresponds to the height of the human body, Since the resistance R corresponds to the human body resistance, that is, the bioelectrical impedance of the human body, the form for obtaining body moisture is as follows.

  The height is a value calculated by the height-related information calculating unit 120, and the resistance C per unit volume of body water can be expressed as a constant value because a certain amount of electrolyte per unit volume is dissolved in the body water. If the human body resistance, that is, the bioimpedance value of the human body is measured by the measuring unit 180, the body moisture of the human body can be obtained.

  The body components that make up the body are mainly composed of four types of components: body moisture, protein, body fat, and mineral (bone). The proportion of these four components in the body weight is about 55: 20: 20: 5, although there are gender and individual differences. However, if the body water content and body fat content are grasped among these components, the remaining components can be obtained.

  Because protein and body water are the main components that form muscles, they have a proportional relationship with each other. That is, healthy muscle is about 73% water and the remaining 27% is protein. Inorganic is the main component that mainly forms bone, and the weight of bone has a close relationship with muscle mass. Therefore, since the protein amount and the inorganic mass can be obtained from the body water amount, if the body water amount and the body fat amount are grasped, it is possible to grasp all four kinds of components forming the body component.

  That is, when the bioimpedance value of the human body is acquired by the measurement unit 1180, the body water content of the human body can be obtained via the body component analysis unit 1190, and the protein amount and the inorganic mass can be obtained from the body water content. The amount of body fat is obtained by removing the protein amount and the inorganic mass from the body water content. Therefore, body component analysis such as body fat of the human body can be performed by measuring the bioimpedance of the human body.
