Abstract
To provide a signal generation apparatus that is used in a ToF camera system especially adopting an indirect system and can suppress occurrence of erroneous distance measurement caused by distance measurement of a same target by a plurality of cameras with a simple configuration. There is provided a signal generation apparatus including a first pulse generator configured to generate a pulse to be supplied to a light source that irradiates light upon a distance measurement target, a second pulse generator configured to generate a pulse to be supplied to a pixel that receives the light reflected by the distance measurement target, and a signal generation section configured to generate a pseudo-random signal for inverting a phase of signals to be generated by the first pulse generator and the second pulse generator.
