Abstract
An imaging device assembly includes a light source, an imaging device formed with a plurality of imaging elements, and a control device. Each imaging element (10) includes a light receiving portion (21), a first charge storage portion (22) and a second charge storage portion (24), and a first charge transfer control means (23) and a second charge transfer control means (24). Under the control of the control device, the imaging element (10) captures an image of an object on the basis of high-intensity light and stores first image signal charge into the first charge storage portion (22) during a first period, and captures an image of the object on the basis of low-intensity light and stores second image signal charge into the second charge storage portion (24) during a second period. The control device obtains an image signal on the basis of the difference between the first image signal charge and the second image signal charge.
