A solid-state imaging deviceaccording to an embodiment of the invention includes: pixel units P(x, y) each of which includes a photoelectric conversion element and an amplifying unit for a pixel unit and which are two-dimensionally arranged; at least one row of optical black units Pob(x, y) each of which includes a photoelectric conversion element, an amplifying unit for a pixel unit, and a light shielding film that covers the photoelectric conversion element, the photoelectric conversion element and the amplifying unit for a pixel unit being the same as those of the pixel unit P(x, y); and at least one row of optical gray units Pog(x, y) each of which includes an amplifying unit for a pixel unit which is the same as that of the pixel unit and to which a reference voltage is input. The value of the reference voltage is less than the value of the output signal from the photoelectric conversion element in a saturated state.

Solid-state imaging device

A solid-state imaging deviceincludes a light receiving section, a first row selecting section, a second row selecting section, and the like. The first row selecting sectioncauses each pixel unit of any m-th row in the light receiving sectionto output data corresponding to an amount of charge generated in a photodiode to a readout signal line L. The second row selecting sectioncauses each pixel unit of any m-th row in the light receiving sectionto output data corresponding to an amount of charge generated in a photodiode to a readout signal line L. The solid-state imaging devicecauses each pixel unit of any m-th row in the light receiving sectionto accumulate charge generated in a photodiode in a charge accumulating section. m1 and m2 are different from each other.

A solid-state image pickup deviceincludes a light receiving section, a first row selecting section, a second row selecting section, a first readout section, a second readout section, and a control section. Data of pixel units of rows in the light receiving sectionselected by the first row selecting sectionare output by the first readout sectionto obtain image pickup data, and further, data of the pixel units of rows in the light receiving sectionselected by the second row selecting sectionare output by the second readout sectionto obtain communication data.

Solid-state image pickup device

A blinking-signal deviceincludes a light receiving section, a row selecting section, a readout section, a detecting section, and a control section. By the row selecting section, charge generated in its photodiode of each pixel unit Pof the (2i&#x2212;1)-th row in the light receiving sectionis accumulated in its charge accumulating section during a first period, and charge generated in its photodiode of each pixel unit Pof the 2i-th row in the light receiving sectionis accumulated in its charge accumulating section during a second period. With the detecting section, it is detected whether or not light reaching the pixel units Pand Pis a blinking signal on the basis of a difference between data Dand Dof the pixel units Pand Poutput from the readout section
