理回路。 In a spatial filter signal processing circuit that receives light from a moving object with a spatial filter and calculates the speed of the moving object from the output signal of the spatial filter, a comparison means that compares the output signal of the spatial filter with a predetermined reference level; , control means for controlling the speed calculation of the moving object based on the output signal of the spatial filter only while the output signal exceeding the reference level is generated from the spatial filter as a result of the comparison by the comparison means. Features a spatial filter signal processing circuit.
