発明の名称 (英語) BIOLOGICAL INFORMATION MEASUREMENT DEVICE, BIOLOGICAL INFORMATION MEASUREMENT METHOD, BIOLOGICAL INFORMATION DISPLAY DEVICE AND BIOLOGICAL INFORMATION DISPLAY METHOD
発明の概要(英語) A biological information measurement device (100) according to an embodiment is provided with a calculation unit (152) and a measurement unit (153). The calculation unit (152) calculates information relating to a pulse wave of a subject on the basis of luminance information of a picture signal of the subject. The measurement unit (153) measures fluctuations in the blood pressure of the subject on the basis of increases and decreases in the information relating to the pulse wave, in accordance with the part of the subject from which the picture signal has been acquired.
従来技術、競合技術の概要(英語) BACKGROUND ART
In recent years, living habits occurs due to the diet and lifestyle-related diseases with an increased prevalence of, but is addressed from to developing, the disease from a stage before it senses, seeks to address the early 'health monitoring' demand has been increasing. That is, such a 'health monitoring' by, in a medical diagnosis from the test well, in the everyday life such a problem with the state of health, early treatment can be performed to construct a bridge to an environment is demanded.
In order to meet such needs, can be carried by the wearable terminal carried by the health care function for starting and attempts, already, a watch, ring, a terminal of various shapes such as a garment has been introduced. These terminals, the pulse wave, electrocardiogram, the acceleration and the amount of activity, such as temperature can be acquired, the acquired signal, heart rate, respiration rate, the number of steps, calorie consumption, sleep state, body temperature information is obtained. However, their routine healthcare is one of important physiological index is little blood pressure information 1 is not of interest in the current situation.
The current, the blood pressure information, and an oscillometric blood pressure measurement, the volume compensation type continuous blood pressure meter, a pulse wave obtained by the total light. An oscillometric blood pressure monitor has, wound around the upper arm cuff and a blood pressure value, are widely used in general households. This type of blood pressure monitor has, the average value of the blood pressure of the pulse number can be measured, the blood pressure value measurement is performed multiple times 1 the diurnal variations of measurement, such as a diagnosis of high blood pressure is used. Volume compensation type continuous blood pressure meter is, for each heartbeat 1 capable of measuring the blood pressure of the device, can be used to assess the autonomic function as well as, Sick Sinus Syndrome diagnosis can also be used. The photoelectric volume pulse wave meter is, the leaflet or finger irradiated with light having a constant with respect to the earlobe, transmission, or changes in amount of light reflected by the blood content in the blood vessel and measuring the change, can be used for the estimation of the blood.
Furthermore, a continuous blood pressure meter of the volume compensation, the photoelectric volume pulse wave meter, an oscillometric blood pressure cannot be measured in a short time of a sudden pressure fluctuations can be measured. The rapid fluctuation of blood pressure in this manner, movement of the straining, excessive stresses, caused by the abrupt change of the ambient temperature, under some circumstances to a sudden change in the physiological state, or be at risk for a living body from the possibility, a technique for estimating the blood pressure variation in the daily life is demanded. However, the volume compensation type continuous blood pressure meter, a large, expensive, and with restraining feeling disadvantageous, for the photoelectric volume pulse wave meter such as concentration of the skin is disadvantageous due to the contact. In this way, in the conventional technique, the problem of the inconvenience and cost of the device, since the use is limited, their routine healthcare it is difficult to use.
On the other hand, in recent years, the biological information on a daily basis in a non-contact method as one of the collection 1, the video image obtained by photographing the skin of the person attention on the analysis. For example, to the skin of the person by analyzing the captured video image, (Heart Rate Variability: HRV) heart rate variability and respiratory rate estimation is performed. By the analysis of such a video image is collected by the biometric information, such as a Web camera or a smart phone, a difficulty is to take the video image is present in the device, for use in the non-contact image completely and a portion of the benefit, their routine healthcare are expected to be used.
