  The A / D conversion circuit 158 converts the voltage signal, the weight signal, the length signal, and the angle signal obtained from the input switching circuit 157 from an analog signal to a digital signal.

  When the body weight / body composition meter 100 is turned on by operating a power switch 141 included in the operation unit 140, the power source unit 170 supplies power to the control unit 110 and each part of the body weight / body composition meter 100. . The timer 160 measures the date and time.

  The camera unit 190 is controlled by the control unit 110 to capture an image of the user 1. The captured image data is stored in the internal memory of the control unit 110 or the memory 120.

  The control unit 110 includes a body weight composition measurement control unit 111, a clothing state determination unit 112, a tare processing unit 113, a measurement result storage control unit 114, and a display control unit 115.

  Note that the body weight measurement process described in FIG. 4 is executed by the control unit 110 in the body weight composition measurement control unit 111, the clothing state determination unit 112, the tare processing unit 113, the measurement result storage control unit 114, and the display control unit 115. As a result, the control unit 110 may be configured, or the control unit 110 may be configured as a hardware circuit.

  The body weight composition measurement control unit 111 measures body weight and body composition as the biological information of the user 1 based on the voltage signal, weight signal, length signal, and angle signal obtained from the A / D conversion circuit 158. To do.

  Specifically, the body weight composition measurement control unit 111 first calculates the weight based on the weight signal. Next, the body composition measurement control unit 111 controls the high-frequency constant current generation circuit 155 to flow a high-frequency constant current to the user 1 from the current application electrodes 151A, 151B, 153A, 153B, and the input switching circuit 157. By controlling, the input to the A / D conversion circuit 158 is switched to a voltage signal, a length signal, and an angle signal based on the potential difference between the two electrodes of the voltage measurement electrodes 152A, 152B, 154A, 154B. Based on the current value of the high-frequency constant current generated by the constant current generation circuit 155, the voltage signal based on the potential difference between the two poles obtained from the A / D conversion circuit 158, the length signal, and the angle signal, The impedance is calculated according to the method.

  Then, the body composition measurement control unit 111 calculates the body composition of the user 1 based on the calculated weight, impedance, and preset height, age, and sex. The body composition is biometric information including body fat percentage, BMI, visceral fat level, basal metabolism, skeletal muscle percentage, body age, and the like. Moreover, in order to calculate body composition, it is necessary to measure body weight beforehand.

  The clothing state determination unit 112 determines whether or not the user 1 is in a clothing state, that is, a state of wearing clothes, based on the user 1 image captured by the camera unit 190. Whether or not the user is in the clothing state is determined by comparing the contour of the user 1 who is not wearing the clothing stored in the memory 120 with the contour of the user 1 in the captured image. A known method can be used as an algorithm for comparing the contours. Thereby, if the degree of coincidence of contours is equal to or greater than a predetermined value, it is determined that it is not in a clothing state.

  When measuring the body composition, the body weight / body composition meter 100 needs to hold the holding unit 20 in the correct posture as described above. Furthermore, it is possible to capture images so that the position and size of the user 1 are substantially the same. For this reason, the degree of coincidence of contours can also be calculated with higher accuracy than when the user's position and size change with each shooting, and whether or not the user is wearing can be determined with high accuracy. .

  In addition, when not wearing anything including underwear, it may be determined that it is not in a clothing state, or when only wearing underwear is not wearing anything including underwear. In addition, you may make it discriminate | determine that it is not a clothing state.

  When the clothing state determination unit 112 determines that the user 1 is in the clothing state, the tare processing unit 113 calculates a tare value corresponding to the clothing of the user 1 from the captured image of the user 1 and measures the body composition. The calculated tare value is corrected (subtracted) from the weight measured by the control unit 111.

  Specifically, when the clothing state determination unit 112 determines that the user 1 is in the clothing state, the tare processing unit 113 extracts and extracts the characteristics of the clothing of the user 1 from the captured image of the user 1. The type of clothes is determined based on the feature, and the tare value is calculated according to the determined type of clothes.

  For example, it is determined whether the clothes are for summer or winter from the shape of the clothes or the month of the measurement date, and the tare value is 500 g for summer and 1 kg for winter.

  Also, in the case of test clothes worn at medical institutions or health checkups, for men (for example, the color is light blue) or for women (for example, the color is pink), or L size, M size or S size, etc. Since the weight is determined in accordance with the size of the clothing, the tare value of the examination clothes can be calculated from the histogram and the size of the clothing color.

  In this case, if colors, shapes, or surface properties (gloss, surface roughness, etc.) that are different from the predetermined clothing are extracted as features of the clothing, it is notified that the clothing is different from the clothing. Further, it may be notified that the tare value cannot be calculated, or may be notified that the user is urged to wear correct inspection clothes.

  In addition, the user registers the image and weight of a specific garment (for example, a nightclothes) in the memory 120 of the body weight / body composition meter 100, and the shape and size of the garment worn by the user of the captured image, If it is determined from the color histogram and surface properties (gloss, surface roughness, etc.) whether it is a specific garment, and if it is determined as a specific garment, the weight registered in advance is set as the tare value. It may be.

  In this way, when measuring the weight immediately after waking up in the morning and before going to sleep at night, the correct weight can be measured without taking off the nightclothes. In addition, a correct body composition based on body weight can be calculated.

  The measurement result storage control unit 114 includes the measurement date, the measurement time, the body weight measured by the body weight composition measurement control unit 111, the weight after the tare processing when the tare processing unit 113 performs the tare processing, Corresponding the body composition calculated by the body composition measurement control unit 111, the body composition calculated by the body weight body composition measurement control unit 111 based on the weight after the tare processing, and information indicating whether or not it is in a clothing state In addition, it is stored in the memory 120.

  In addition, the measurement result storage control unit 114 includes the drawing angle and length of the cable 30 used in the process of calculating the body composition, or the part length of the user's 1 arm and the trunk and legs calculated based on them. The part length including the part is stored in the memory 120.

  Although the memory 120 is consumed, the captured image of the user 1 may also be stored in association with each other. However, in the case of the present embodiment, whether or not the user is in the clothing state can be specified by the information indicating whether or not the user is in the stored clothing state without storing the image of the user 1.

  In addition, the measurement result storage control unit 114 stores both the body weight measured by the body weight composition measurement control unit 111 and the weight after the tare processing when the tare processing unit 113 performs the tare processing. I did it. However, the present invention is not limited to this, and either weight may be stored. Moreover, you may make it memorize | store one of a body weight and a tare value in the memory 120. FIG.

  The display control unit 115 controls the display unit 130 to display the weight and body composition immediately after measurement and the history weight and body composition stored in the memory 120.

  Note that the image of the user 1 may be displayed on the display unit 130 along with the weight immediately after the measurement, whether or not the clothes are in the clothes. However, if it is determined that the user is not in a clothing state and the image of the user 1 is displayed side by side with the weight, the user can show his / her body shape that is not in the clothing state along with the weight, and the motivation of the diet can be further improved. Since it can give strongly to a user, it is preferable.

  FIG. 4 is a flowchart showing the flow of the body weight measurement process executed by the body weight / body composition meter 100 according to this embodiment. Referring to FIG. 4, in step S <b> 101, control unit 110 determines that the cable drawing angle and length, or the length of the arm portion and the length of the portion including the trunk and legs are within the reference range. It is determined whether or not the posture of the user 1 is correct.

  Whether it is within the reference range is determined based on, for example, whether it is within a predetermined ratio range (99% to 101% range) of the average value of the history.

  When it is determined that the posture is not correct (when NO is determined in step S101), in step S102, the control unit 110 controls the display unit 130 to display that the posture is correct. Then, the control part 110 returns the process to perform to the process of step S101.

  If it is determined that the posture is correct (YES in step S101), in step S103, the control unit 110 controls the display unit 130 to display that the shooting button 146 is operated if preparation for shooting is good. To do.

  In step S <b> 104, the control unit 110 determines whether or not a shooting operation has been performed when an operation signal indicating that the shooting button 146 has been operated is input.

  If it is determined that the shooting operation has not been performed (NO in step S104), control unit 110 repeats the process in step S104. If it is determined that a shooting operation has been performed (YES in step S104), in step S105, the control unit 110 controls the camera unit 190 to capture the image of the user 1, and stores the captured image in the memory. Control is performed so as to be temporarily stored in the internal memory of 120 or the control unit 110.

  Next, in step S106, the control unit 110 controls the input switching circuit 157 so that the weight signal from the weight measurement unit 156 is input to the A / D conversion circuit 158, and the A / D conversion circuit. Based on the weight signal converted into a digital signal in 158, the weight is calculated.

  Next, in step S111, the clothing state of the user 1 is determined according to the determination method described in FIG. In step S112, control unit 110 determines whether or not the clothing is in the clothing state as a result of the determination in step S111.

  When it is determined that the user is in the clothing state (when YES is determined in step S112), the control unit 110, in accordance with the method described in FIG. 3, in step S113, from the image of user 1 captured in step S105, The feature of the clothing is extracted, and in step S114, the type of clothing is determined based on the extracted feature of the clothing. In step S115, the tare value is calculated according to the determined type of clothing, and is calculated in step S116. The weight calculated in step S106 is corrected with the tare value.

  When it is determined that the user is not in a clothing state (when NO is determined in step S112), and after step S116, in step S117, the control unit 110 calculates the weight calculated in step S106 and the tare process in steps S113 to S116. Is executed, the weight after the tare process and the clothing determination result indicating whether or not the clothing is in the clothing state are associated with each other and stored in the memory 120.

  Next, in step S118, the control unit 110 displays the weight calculated in step S106 when the tare process is not executed, and displays the weight corrected in step S116 on the display unit 130 when executed. Control is performed so that the captured image of the user 1 photographed in S105 is also displayed on the display unit 130 side by side. Thereafter, the control unit 110 returns the process to be executed to the caller process of this process.

  (1) As described above, the body composition monitor 100 according to the present embodiment is a biological information measuring device that measures body weight and body composition, which is biological information that requires measurement of body weight in the measurement process, A control unit 110, a memory 120, a weight measurement unit 156, and a camera unit 190 are provided. The control unit 110 controls the camera unit 190 to capture an image of the user 1, determines whether the user 1 in the captured image is in a clothing state, and controls the weight measurement unit 156 to measure the weight. Then, the determination result as to whether or not the user is in the clothing state and the measured weight are associated with each other and stored in the memory 120.

  For this reason, even if it is a case where it is a case where it is a case where it is a list display or a history display with a body weight whether it is a clothing state, it can be notified to the user 1 easily whether it was a clothing state.

  Further, it is not necessary to store an image in order to inform the user 1 whether or not it is in a clothing state. For this reason, the capacity of the memory 120 can be smaller than the case of storing images, and the manufacturing cost can be reduced.

  (2) If the control unit 110 further determines that the user is in the clothing state, the control unit 110 calculates a tare value corresponding to the clothes of the user 1 from the captured image, and calculates the calculated tare value from the measured weight. And the corrected weight is further stored in the memory 120 in association with each other.

  For this reason, compared with the case where the user manually inputs the tare value before the measurement, according to the weight / body composition meter 100 of this embodiment, the complexity of manually inputting the tare value can be eliminated. Further, compared with the case where the tare value is determined by the subjective judgment of the user, the weight / body composition meter 100 of this embodiment can objectively determine the tare value.
