1. An imaging device assembly comprising:
a light source that illuminates an object;
an imaging device; and
a control device that controls the light source and the imaging device,
wherein
the imaging device includes a plurality of imaging elements,
each imaging element includes:
a light receiving portion;
a first charge storage portion and a second charge storage portion; and
a first charge transfer control means that controls, under control of the control device, transfer of electric charge stored in the light receiving portion to the first charge storage portion, and a second charge transfer control means that controls, under control of the control device, transfer of electric charge stored in the light receiving portion to the second charge storage portion,
the imaging device assembly is operated in a first operation mode,
in the first operation mode,
during a first period, the imaging element under control of the control device captures an image of the object on a basis of high-intensity light emitted from the light source and stores first image signal charge obtained at the light receiving portion into the first charge storage portion, and,
during a second period, the imaging element under control of the control device captures an image of the object on a basis of low-intensity light and stores second image signal charge obtained at the light receiving portion into the second charge storage portion, and
the control device obtains an image signal, on a basis of a difference between the first image signal charge stored in the first charge storage portion and the second image signal charge stored in the second charge storage portion.
