Claims (1)

[Scope of utility model registration request] An infrared camera that uses a two-dimensional image sensor that photoelectrically converts incident light in the infrared region, a detector that automatically detects a target from the output video signal of the infrared camera, and a servo that changes the viewing direction of the infrared camera. In an infrared search device that basically consists of a mechanism, a means for searching by changing the viewing direction of the infrared camera to the rotation direction, a means for detecting the angular velocity of the rotation axis, and an accumulation time of the image sensor (photoelectric conversion time). ); a first adder that performs addition processing on signals of the number of pixels N corresponding to the angle moved during the period of movement during the output time of the next N pixels; While the adder is outputting the signal, the second adder also performs addition processing for N pixels, and then outputs the added signal during the output time for N pixels, and the second adder operates alternately. An infrared search device comprising: a switch that alternately switches the output signals of the first and second adders to output a continuous signal.
