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.
