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.

Abstract: A distance measuring device includes a control unit and a measuring unit. The control unit controls a photodetector unit. The photodetector unit includes a photoelectric transducer element and an output unit. The photoelectric transducer element generates electrical charges on receiving light reflected from a target as a part of measuring light emitted from a light-emitting unit. The output unit outputs an electrical signal representing a quantity of the electrical charges generated by the photoelectric transducer element. The measuring unit calculates, in accordance with the electrical signal, a distance to the target within a measurable range. The control unit sets, in each of a plurality of intervals that form the measurable range, a conversion ratio of the quantity of the electrical charges generated by the photoelectric transducer element to a quantity of the light received by the photoelectric transducer element.
