Image-capturing device and image-capturing system

An image-capturing device comprising:

• a light-receiving substrate including light-receiving units, and having a surface on which drive lights corresponding to the light-receiving units are received, respectively, wherein the light-receiving units perform active processing to produce drive signals corresponding to the received drive lights, respectively;
• and
• a photoelectric converting substrate including photoelectric converting units that are driven by the drive signals, and having a surface on which the photoelectric converting units receive external light,
• wherein the light-receiving substrate is stacked on the photoelectric converting substrate so that the surface of the light-receiving substrate on which the drive lights corresponding to the light-receiving units are received, and the surface of the photoelectric converting substrate on which the photoelectric converting units receive the external light, face away from each other.
