Abstract: An imaging apparatus includes a unit pixel including a pixel electrode, a charge accumulation region electrically connected to the pixel electrode, and a signal detection circuit electrically connected to the charge accumulation region; a counter electrode facing the pixel electrode; a photoelectric conversion layer disposed between the electrodes; and a voltage supply circuit configured to selectively apply any one of first, second, and third voltages between the electrodes. The photoelectric conversion layer exhibits first and second wavelength sensitivity characteristics in a wavelength range when the voltage supply circuit applies the first and second voltages between the electrodes, respectively, and becomes insensitive to light in the wavelength range when the voltage supply circuit applies the third voltage between the electrodes.

Abstract: A method is for controlling an imaging device that allows switching of an operation mode between a first mode to perform imaging in a first imaging wavelength band and a second mode to perform imaging in a second imaging wavelength band different from the first imaging wavelength band. The method includes: determining whether ambient light includes near-infrared light based on information obtained in the first mode and information obtained in the second mode; and maintaining or changing the operation mode.
