Signal generation apparatus

Abstract

To provide a signal generation apparatus for use with a ToF camera system that especially adopts the indirect system, which can be ready for various modulation frequencies with a simple configuration. A signal generation apparatus is provided which includes a first pulse generator configured to generate a pulse to be supplied to a light source that irradiates light to a distance measurement target, a second pulse generator configured to generate a pulse to be supplied to pixels that receive light reflected by the distance measurement target, and a switching section configured to switch a setting of a modulation frequency of the first pulse generator and the second pulse generator within a predetermined period.
