Abstract
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−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
