Sensor device and semiconductor device

Abstract

A sensor device includes: multiple pixel circuits each of which includes a light receiver and generates an event signal corresponding to presence or absence of an event in accordance with a light reception result of the light receiver; and a pre-processing circuit that generates processing information on the basis of the multiple event signals, and supplies the processing information to a processing circuit including a neural network. The pre-processing circuit includes: a first weighted addition circuit that performs a weighted addition process on the basis of two or more of the event signals generated by respective two or more pixel circuits among the multiple pixel circuits; and a first determination circuit that generates a first feature value signal on the basis of a result of the weighted addition process in the first weighted addition circuit. The pre-processing circuit generates processing information based on the first feature value signal.
