The disclosed imaging device includes pixels each including a photoelectric convertor, a focus controller controlling a focal position of light, and a pixel controller controlling charge accumulation in the photoelectric convertors and readout of signals from the pixels. The pixels include a first pixel outputting signal corresponding to light in a first wavelength band and a second pixel outputting signal corresponding to light in a second wavelength band. The pixel controller executes, during one frame, a first period of accumulating charge in the photoelectric convertor of the first pixel in a state that the light in the first wavelength band is focused on, a second period of accumulating charge in the photoelectric convertor of the second pixel in a state that the light in the second wavelength band is focused on, and a third period of reading out signals corresponding to amount of charge generated in the photoelectric convertors.
