示外両（東が得られない。Conventional configuration and its problems Traditionally, infrared imaging cameras used in this type of device incorporate a pyroelectric infrared detection element into a bincon tube, and detect the infrared distribution (color) in one reading by scanning an electron beam. The J2 unit outputs TV No. 18. Since a pyroelectric infrared detection element is used in this way, the field of view can be scanned by swinging the camera, or infrared light can be detected. If you don't make it intermittent, you won't be able to get the east side.

1, but is limited only to observation of the temperature change distribution in the intestines. Therefore, normally, a switch is installed in the camera to cut off the infrared light -S+ to cut off the infrared human radiation. However, since the temperature of this chip 517 is approximately the same as the room temperature, the obtained infrared signal is the difference between the room temperature and the subject temperature, and if the room temperature changes, the signal changes. Therefore, although the relative temperature distribution of the object can be measured, the absolute temperature cannot be measured. In addition, infrared cameras output temperature distribution images of the subject, but the wavelength of the infrared rays they observe is usually around 10 μm, making it much more difficult to focus the images than with visible images. . In addition, since the image taken by an infrared imaging camera is vastly different from the visible image, when analyzing it as temperature distribution data after observation,
In order to clarify what was actually observed and what part of it was observed, visible television cameras are sometimes installed adjacent to each other to simultaneously observe infrared and visible images. In the case of distance, there is a problem in that there is a slight difference between the two images due to parallax.

せることができる。The visible television camera 2 has a visible vidicon tube 9 built into a structure 8, and the base of a cylindrical body 11 holding a visible lens 1o is screwed into the front side of the structure 8 so as to be able to move forward and backward. Therefore, by rotating the cylinder 11 with respect to the structure 8, the visible lens 1o can be focused. A support member 12 is attached between the front side portions of the structure 3 of the 5-infrared imaging camera 1 and the structure 8 of the visible television camera 2, and a pair of gears 13 and 14 are pivotally supported on this support member 12. Each gear 13゜14 is meshed with each other (C), and each gear 13゜14

The rotation of the gear 14 causes the visible lens 10 of the visible television camera 2 to advance if 1, and the infrared lens 10 of the infrared imaging camera 1 advances by the gear 13 in conjunction with this by focusing. The setting is such that focusing is performed by moving backwards. This visible television camera 2 is designed to read and output a visible image of one subject, and is equipped with a sequential image memory 15 and a monitor 16.
It is connected to the. A reference blackbody furnace 17 is placed on the front side of the infrared imaging camera 1 in a direction perpendicular to its optical axis.

ならない。Next, the effect of the above real ;:+E sequence will be explained. The cam 21 is rotated by the drive of the motor, and the movable double-sided reflection 'r#
, 19 are reciprocated in the open and closed states within an angle range of 45° as described above. When the movable double-sided reflector 19 is in the open state, the infrared rays of the subject are made incident on the infrared camera 1 as shown in FIG. Output from terminal 7. On the contrary, when the movable double-sided reflective mirror 19 is in a closed state, the light rays from the subject are incident on the visible television camera 2, and the visible image is read and output by the visible television camera tube 9. Although the image signal is intermittent, it is stored in the image memory 15 and is always continuously displayed on the monitor 16 as -C image ra. Now open and close the movable double-sided reflector 19, li! If iJ1g'l is K, the opening and closing state will be approximately S4 seconds each, and the state will be in the middle for 2 seconds. The scanning speed of the visible vidicon tube 9 is set to '/6.
Since one screen is read in ° seconds, frame signals for about 4 screens can be read out for one question when open. However, since it is a -2 television camera, two frames make up one image using the interlace method, and in that sense, it is two images. Image memory is stable 1 of 2 images every % seconds
Memorize images, e.g. second and third frames, i.e.
Always outputs memory signals in TV No. 1 mode. As a result, it is possible to constantly monitor the visible image (elephant) that is updated every Z seconds.Therefore, by operating the gear 14, the visible lens 1o is focused 7 times, and in conjunction with this, it is automatically When the movable double-sided reflector 19 is in the open state, the infrared lens 5 of the infrared imaging camera 1 is focused, and the infrared rays from the reference blackbody furnace 17 are incident on the infrared imaging camera 1. It is scanned and outputted by the infrared vidicon tube 4.The temperature of the reference blackbody furnace 17 can be set arbitrarily according to the temperature of the subject, so that the body temperature of the subject can be measured.This standard High measurement accuracy can be maintained by setting the set temperature of the black body furnace 17 to a temperature close to the subject temperature.In this way, the installation of the reference black body furnace 17 makes it possible to measure absolute temperature, and With the maximum sensitivity, it is now possible to observe objects with relatively high temperatures.For example, when observing a subject at 2o○℃ using the conventional method, it will detect a temperature difference (~180℃) from the regular Chikutsuba. The lens must be calibrated and observed so that the infrared signal output does not become saturated.At that time, the sensitivity is 3.
As two gradations, each gradation is approximately 6°C1. It becomes ζ. on the other hand,
In the apparatus of the present invention having the base T's blackbody furnace 17, the weir quasi-blackbody furnace 17 is set at 160°C, 160°C-190°C.
It can be observed with a sensitivity of 1°C per gradation between 'C. Even if necessary (maximum sensitivity o, s';') one gradation is also possible.The temperature range of the subject must be within 16 degrees Celsius at the moment.

ので、その間に読み出せる信号は６フレ一ム分となる。FIG. 4 shows an embodiment of a J-type pond in which movable double-sided reflecting mirrors 19 are connected in solid light. In this embodiment, the base side of the double-sided reflector 190 of May is formed by a permanent magnet 19a, and this permanent magnet 19a is alternately sucked or repelled by electromagnets 23 installed at two positions, so that the movable double-sided mirror 190 The reflecting mirror 19 is rotated, so that the opening and closing time can be maintained at 1 second, and the time required to move from opening to closing or vice versa can be reduced to 1/40 seconds. Since the opening or closing time can be set to 1 second, the signal that can be read out during that time is 6 frames.

However, if the overall size and the complexity of the mechanism of the focus interlocking adjustment means are not a problem, the reflecting mirror 22 is not necessary if the visible television camera 2' is installed at right angles to the infrared imaging camera 1.

The system is configured to selectively switch between a state in which the infrared rays from the reference black body furnace enter the infrared imaging camera and a state in which the light rays from the subject enter the visible television camera. Therefore, the visible television camera can be easily focused, and the R11 station can obtain unobtrusive infrared and visible images, making it possible to easily manage out-of-range image data.
また基準黒体炉を用いているので、被写体の動体温度測
