Abstract: An imaging apparatus comprises a semiconductor substrate, a photoelectric converter, a charge storage region, and an amplification transistor. The photoelectric converter includes a pixel electrode, a counter electrode, and a photoelectric conversion layer. The photoelectric conversion layer is positioned above the semiconductor substrate and is disposed between the pixel electrode and the counter electrode. Charge generated by the photoelectric converter is stored in the charge storage region. The amplification transistor includes a source, a drain, and a gate electrode. The gate electrode is electrically connected to the charge storage region. In a plan view, the width of the drain of the amplification transistor is less than the width of the source of the amplification transistor.

Abstract: A method for controlling an imaging device having 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, and that allows switching of an operation mode from the first mode to the second mode or from the second mode to the first mode. The method including causing the imaging device to perform imaging in the first mode or the second mode; determining, with a predetermined frequency or in response to a predetermined trigger, whether to maintain a current operation mode or switch the current operation mode on the basis of first image information in the first imaging wavelength band and second image information in the second imaging wavelength band; and in accordance with the determination, selectively maintaining the current operation mode or switching the current operation mode.
