  • An analog-to-digital converter 21 amplifies the analog signal output from each pixel of the infrared imaging device 9 with an internal analog amplifier and converts it into, for example, a 14-bit digital signal. This digital signal is called luminance. The luminance of each pixel is correlated to temperature according to a predetermined conversion formula to form a thermal image.
  • the multiple pixels of the infrared imaging device 9 have different sensitivities to the amount of light, output offsets, and their temperature characteristics. For this reason, a reference thermal image is acquired and stored in advance, and a thermal image is obtained by outputting the difference between the reference thermal image and the input signal from the subject.

  • the sensitivity adjustment unit 26 may adjust the gain of the digital output of the analog-digital converter 21 to adjust the sensitivity of the corresponding pixel.
  • Sensitivity is the amount of change in luminance when the temperature of the subject changes by 1°C.
  • the sensitivity adjustment unit 26 sets the sensitivity of pixels corresponding to the human detection area, which is the area in the thermal image where a person 2 is detected, higher than that of pixels corresponding to other areas. For example, the sensitivity of pixels in the human detection area is set to 30 digit/K, and the sensitivity of pixels outside the human detection area is set to 10 digit/K, and these are stored in the memory unit 14.

  • the safety device 4 controls the output of the heating device 1 based on the detection result of the human detection unit 12 and the temperature information calculated by the temperature calculation unit 13. For example, the safety device 4 automatically controls the output of the heating device 1 when the person 2 is not in front of the heating device 1. Specifically, if the output of the heating device 1 is reduced or turned off when the person 2 is not in front of the heating device 1 and the heating device 1 has been on for a predetermined time, it is possible to prevent forgetting to turn it off and reduce energy consumption. Furthermore, when the person 2 is not in front of the heating device 1 and the temperature of the heating device 1 is too high, the safety device 4 reduces or turns off the output of the heating device 1. This makes it possible to prevent abnormal heat generation of the heated object 3, thereby improving the safety of the heating device 1.
  • safety device 4 prevents automatic control of the output of heating device 1. This allows person 2 to manually control the heat of heating device 1. Furthermore, safety device 4 will not automatically reduce the heat even if person 2 intentionally increases the heat. This prevents person 2's operation from being hindered and convenience from being impaired.

  • the high-temperature subject and the person can be displayed simultaneously on the thermal image using an inexpensive MCU, making it possible to accurately detect person 2 on the thermal image.
  • the temperature of the heat source can also be measured at the same time. Furthermore, by setting the human detection area 27 in advance, people who are not approaching the equipment, such as people walking in the aisle, will not be displayed on the thermal image, preventing erroneous detection.

  • the temperature calculation unit 13 calculates the temperature of each pixel (step S22).
  • the offset setting unit 28 determines whether there is a pixel outside the human detection area 27 that is hotter than the threshold (step S23). If there is, the offset setting unit 28 performs an offset process to reduce the brightness value output from the infrared imaging device 9 so that the temperature of the pixel becomes the same as the threshold, and outputs the result to the thermal image generation unit 11 (step S24).
