Abstract
An imaging apparatus includes a unit pixel including a pixel electrode; a counter electrode facing the pixel electrode; a photoelectric conversion layer disposed between the pixel electrode and the counter electrode; and a computing circuit that acquires a first signal upon a first voltage being applied between the pixel electrode and the counter electrode, the first signal corresponding to an image captured with visible light and infrared light and a second signal upon a second voltage being applied between the pixel electrode and the counter electrode, the second signal corresponding to an image captured with visible light, and generates a third signal by performing a computation using the first signal and the second signal, the third signal corresponding to an image captured with infrared light.
