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.

Abstract: An imaging device includes a photoelectric converter including first and second electrodes, a photoelectric conversion layer therebetween, and a hole-blocking layer between the first electrode and the photoelectric conversion layer; and a signal detection circuit electrically connected to the first electrode. The hole-blocking material has an electron affinity lower than both a work function of the first conducting material and an electron affinity of the first photoelectric conversion material. The photoelectric conversion unit is applied with a voltage between the first and second electrodes, and responsive to the voltage within a range from a first voltage to a second voltage, shows that a density of current passing between the first and second electrodes when light is incident on the photoelectric conversion layer becomes substantially equal to that when no light is incident thereon. A difference between the first voltage and the second voltage is 0.5 V or more.

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.
