Abstract:
1. A signal processing system comprising: an optical apparatus including a solid-state image pickup device configured to convert light incident thereon into an electrical signal and an optical element configured to allow light to be incident on the solid-state image pickup device; and a signal processing apparatus to which the optical apparatus is connected; wherein the solid-state image pickup device includes wherein the signal processing apparatus includes wherein, when the signal processing apparatus is turned on, power is supplied to the light receiving unit of the signal processing apparatus and, subsequently, power is supplied to the solid-state image pickup device, and wherein power is supplied to the light modulation unit of the solid-state image pickup device and, subsequently, is supplied to the pixel unit and, subsequently, is supplied to the light emitting unit of the signal processing apparatus, and wherein, when the signal processing apparatus is turned off, power supply to the light emitting unit of the signal processing apparatus is stopped and, subsequently, power supply to the pixel unit of the solid-state image pickup device is stopped and, subsequently, power supply to the light modulation unit is stopped, and wherein, after power supply to the solid-state image pickup device is stopped, power supply to the light receiving unit of the signal processing apparatus is stopped.
