Abstract:
1. A variable sensitivity imaging device comprising: a substrate; a first photosensitive structure comprising: a second photosensitive structure comprising: a signal reading section, formed on the substrate, that reads a first signal corresponding to photo-charges that are generated in the first photosensitive structure by incidence of light and a second signal corresponding to photo-charges that are generated in the second photosensitive structure by the incidence of light; and a pulse voltage applying section that applies a first pulse voltage between the first pixel electrode layer and the first opposing electrode of the first photosensitive structure, and a second pulse voltage between the second pixel electrode layer and the second opposing electrode of the second photosensitive structure, wherein the first photosensitive layer of the first photosensitive structure is stacked above the second photosensitive layer of the second photosensitive structure, and wherein a time width of the first pulse voltage is different from a time width of the second pulse voltage.
