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: The present disclosure allows a light-emitting device to detect a failure of a light-emitting circuit without affecting the waveform of a pulse current to be supplied to a light source element. The light-emitting device includes: a light-emitting circuit including a light source element; and a power supply configured to supply electric charges to the light-emitting circuit. The light-emitting circuit is provided between a power supply node and a ground node. The power supply is connected to the power supply node via a power supply line. A monitor detects an abnormal state of the light-emitting circuit by monitoring the voltage of the power supply line or the internal voltage of the power supply.

Abstract: An information processing system includes an object information generator and an output unit. The object information generator generates object information. A piece of the object information indicates a feature of an object present in a target distance section. The target distance section is one selected from a plurality of distance sections defined by dividing the distance measurable range in accordance with differences in elapsed times from a point of time when a light emitting unit emits a measuring light. The object information generator generates the piece of the object information based on a distance section signal associated with the target distance section. The output unit outputs the object information.
