1. A signal generation apparatus comprising:
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 selection circuit configured to select a duty cycle of a signal to be outputted from the first pulse generator from between a first duty cycle and a second duty cycle different from the first duty cycle, wherein the first pulse generator includes a main pulse generator and a sub pulse generator and wherein the sub pulse generator is configured to control the second duty cycle in response to a phase setting input.
