Abstract: A biological information detection device including: a light source that, in operation, emits irradiation light for irradiating a test portion of a subject; a light detector that, in operation, detects light reached from the test portion and that outputs an electrical signal corresponding to the light; and a calculation circuit that, in operation, generates a signal of biological information related to a blood flow in a target area in the test portion based on the electrical signal. The light detector is an image sensor. The electrical signal includes an image signal obtained by the image sensor. The calculation circuit, in operation, detects a magnitude of an inclination of an orientation of the test portion with respect to a reference orientation by image recognition based on the image signal, and determines the target area according to the magnitude of the inclination of the orientation of the test portion.

Abstract: A photodetection device including an image sensor that includes fifth pixels and sixth pixels; an interference element that includes fifth incident regions; and illumination that emits light in a first wavelength band and a second wavelength band. The interference element causes first interference of light in the first wavelength band incident on two fifth incident regions, and guides resultant light of the first interference to any of the fifth pixels and guides another part of the light in the first wavelength band to any of the sixth pixels, and causes second interference of part of the light in the second wavelength band incident on the two fifth incident regions, and guides resultant light of the second interference to any of the fifth pixels and guides another part of the light in the second wavelength band incident on the two fifth incident regions to any of the sixth pixels.
