Abstract

PURPOSE:To economically constitute a highly accurate infrared ray sensor by converting a temperature to be a measuring reference into a digital value and correcting it by adding or subtracting a necessary digital value from said value. CONSTITUTION:The output signal of an infrared ray sensor 2 is converted into an image signal by a parallel/serial converter circuit 3, passed through an amplifier 4 and a signal processing circuit 5 and inputted to a display means 6 as a brilliance- modulated signal. The signal processing circuit 5 has functions of converting the output signal of the amplifier 4 into a digital signal, and removing a given DC component from it before converting it into an analog signal again and applying it to the display means 6.
