Imaging device assembly, three-dimensional shape measuring device, and motion detecting device

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.
