A photodetection device, a photodetection method, an image sensor and an image pickup method can increase the number of pixels, while suppressing degradation of the S/N ratio. The photodetection device includes a spectroscopic element formed by means of an optical microresonator having a plurality of resonant wavelength bands differentiated by positions as a function of a geometric structure and a plurality of photoelectric conversion elements arranged at different positions to detect light of the plurality of resonant wavelength bands.
