Imaging apparatus including unit pixel, counter electrode, photoelectric conversion layer, and computing circuit

An imaging apparatus comprising:

• a 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 pixel electrode and the counter electrode,
• the photoelectric conversion layer converting first light having a first wavelength band into a first electrical signal upon a first voltage being applied between the pixel electrode and the counter electrode,
• the photoelectric conversion layer converting second light having a second wavelength band, the second wavelength band being different from the first wavelength band, into a second electrical signal upon a second voltage being applied between the pixel electrode and the counter electrode, the second voltage being different from the first voltage;
• and
• a computing circuit that acquires a first signal on a basis of the first electrical signal upon the first voltage being applied between the pixel electrode and the counter electrode, the first signal corresponding to an image captured with the first light,
• the computing circuit acquiring a second signal on a basis of the second electrical signal upon the second voltage being applied between the pixel electrode and the counter electrode, the second signal corresponding to an image captured with the second light,
• the computing circuit generating a third signal by performing a computation using the first signal and the second signal, the third signal corresponding to an image captured with third light having a third wavelength band, the third wavelength band being different from both the first wavelength band and the second wavelength band.
