Description of the Related Art Conventionally, it has been known to use a psychocurrent phenomenon of a person as an attempt to measure a psychological change and a mental change of a person. This is to observe an electrodermal reaction (GSR), which is to attach electrodes to two places on the skin of a subject, introduce the electrodes into an ammeter, and measure a change in current caused when a stimulus is given. The change in current is amplified and measured by passing a slight current (6 V, 100 μA or less) that is not actually felt on the skin.

斜線部分）。First, since there are individual differences in the human face temperature and the fact that it varies depending on the ambient temperature, the measured temperature range of the face temperature is set to 29, 6 ° C. to 36 ° C.
It decomposed into 16 steps at 0 and 4 ° C. Since the face temperature sometimes deviates from the set temperature range and a plurality of small areas are created, one frame (256 × 100 dots) of image data obtained by the infrared device 2 is generated.
Was divided into 320 to form a box of 80 dots. When there are a plurality of small temperature regions (black circles in FIG. 2C) in the same box,
Alternatively, when included in adjacent boxes (upper and lower left in FIG. 2C), a group of eight adjacent boxes is subjected to edge tracking type boundary detection processing to determine the target area of the same object (FIG. 2C).

It is calculated by the formula. Radiant heat Q1 = Σ ・ ε (T o Four-Ta Four) [W / m2] Q1 : Unit area (m2) Radiant heat from σ: Stefan-Boltzmann constant 5.67 × 10-8[W / m2・ KFour] Ε: Emissivity(6) To: Absolute temperature of the object surface [K] Ta: Atmospheric temperature away from the object [K] (ambient temperature) Natural convection transfer heat quantity Q2= Hm (to-Ta) [W / m2] Q2: Unit area (m2) Hm: Average natural convection heat transfer coefficient [W / m2・ ℃] to: Temperature of object surface [° C] ta: Air temperature away from the object [℃] Average natural convection thermal conductivity Hm = 1.173 ・ (to-To)-1/3 From the above equation, the total radiant heat quantity is as follows. Q = Q1+ Q2 [W / m2] Next, prepare a circular stage, and use the infrared camera 1 and red mentioned above.

Printed on. To explain, in FIG. 3A, the ambient temperature is measured as the room temperature at the initial stage of measurement, and the room temperature rises with the passage of time, so that the facial radiation heat quantity apparently shows a rising tendency. FIG. 3B shows the deviation of the facial temperature of the subject himself / herself for four days (8 hours) by approximating the average value with respect to room temperature change by a regression line. FIG. 3C shows the average value of the amount of heat radiated from the face of the subject on the day after the end of the drama, and the deviation from the average value is re-displayed as a change over time. A large change was observed before the end of (2 hours) in B and C of FIG. Later, it was found that this change caused psychological shock (awareness) in the subject at this point. FIG. 4 shows an enlarged view of the heart rate at the same time. This Figure 4 shows the deviation from the average of the subject's own radiant heat curve (bottom)
And the heart rate (upper row) of the subject at that time is also shown. On the right side of the figure, the change in heart rate and the change in the amount of heat radiated from the face are almost the same. However, at the mark * on the left side, the heart rate (upper part) has hardly changed, although the radiant heat amount (lower part) has changed. From this, it is understood that the psychological shock appears as the amount of heat radiated from the face even if it does not appear in the heart rate.

This has the advantage of being able to infer physiological changes that could not be inferred from the deviation from the subject's own average value. As described above, the method of calculating the average value for calculating the deviation of the test subject is shown in FIGS.
There are two types. FIG. 3B shows the deviation calculated based on the average value of the subject himself / herself for four days and FIG. 3C shows the deviation based on the average value of the subject on that day. There is no big difference between the waveforms of both figures, and the method of FIG. 4C is sufficient for observing the psychological changes of the subject himself. The method of FIG. 4C may be sufficient, particularly when the monitor is analyzed after the interview, such as counseling.
