Abstract: The photosensor includes an APD that has a multiplication region including a photoelectric converter and includes a first capacitor connected to the multiplication region in parallel, and a first transistor connected between the APD and a first power supply (voltage VC). The first transistor applies a reverse bias of a power supply voltage (VC-VA), which is larger than a breakdown voltage VBD, between an anode and a cathode of the APD during a bias setting period by connecting the APD to the first power supply, and stops an avalanche multiplication phenomenon during a light exposing period by disconnecting the APD from the first power supply to accumulate charges generated by the avalanche multiplication phenomenon in the first capacitor.

Abstract: In an object information generation system, an imaging unit is configured to capture a plurality of segment images respectively corresponding to a plurality of distance segments dividing a target space. In a signal processor, the object region extraction unit extracts, from a plurality of segment images, an object region that is a pixel region including an image of the object. An object information generation unit determines, for the object region, a window in which calculation-target pixels are cut out, and generates distance information of the object by calculation using information of a plurality of pixels in the window for two or more segment images.

Abstract: An object detection system includes a light emitter, an optical sensor, a controller, and a signal processor. The controller controls the light emitter and the optical sensor to cause range segment signals to be outputted from the optical sensor for corresponding range segments. The signal processor includes: a target object information generator that includes a plurality of generators (a first generator through a fifth generator) capable of operating in parallel and generates items of target object information indicating features of target objects for the range segments; and storage that stores the items of target object information. The target object information generator compares a past one of the items of target object information stored in the storage with a feature of a current one of the target objects detected by the optical sensor to generate a corresponding one of the items of target object information.

Abstract: An imaging device includes a photoelectric converter generating signal charge; a charge storage region storing the signal charge; a first transistor having a gate coupled to the charge storage region; a second transistor having a source and a drain; and voltage supply circuity supplying voltages varying with time. An output of the first transistor is fed back to the second transistor and is supplied to the charge storage region. A reset operation for discharging the signal charge in the charge storage region includes a first reset operation and a second reset operation. In the first reset operation, the second transistor changes from an OFF state to an ON state and then changes to an OFF state. In the second reset operation, the voltage supply circuity supplies the voltages to a gate of the second transistor so that the second transistor gradually changes from an OFF state to an ON state.
