摘要： An infrared solid state imaging device includes an infrared detection element unit having heat sensitive pixels, an AD conversion unit which conducts analog-to-digital conversion on an infrared image signal obtained by the infrared detection element unit, and a digital signal processing unit which converts the image signal converted to a digital signal. The digital signal processing unit stores an image value produced from the digital signal, and acquired in a frame immediately preceding a current frame, subtracts an image value obtained by multiplying the image value acquired in the frame immediately preceding the current frame by a predetermined constant α in a range of 0 to 1, from an image value acquired in the current frame, and conducts processing of multiplying a resultant image value obtained by the subtraction by 1/(1−α) so that an infrared image with less afterimage is provided.
