  • Publication number: 20190056496
    Abstract: First and second types of object detectors, a sensing device, and a mobile apparatus. The first and second types of object detectors include a light source configured to emit light, photoreceptor configured to receive the light reflected by an object, and a binarizing circuit configured to binarize a signal sent from the photoreceptor at a threshold Vth. In the first and second types of object detectors, object detection processes are performed in a same direction until a high-level signal is output M times from the signal binarized by the binarizing circuit. In the first type of object detector, a value of the M is determined based on an incidence of shot noise where peak intensity exceeds the threshold Vth in the photoreceptor. In the second type of object detector, a threshold Vth is set based on a value of the M.
