Abstract: An imaging device includes a light source, an image sensor, and a controller. Each pixel of the image sensor includes first and second accumulators and a discharger. The controller, while a component of light from the light source reflected by the surface of a target is incident on the image sensor, causes the accumulators to accumulate signal charge not discharged to the discharger, by setting the image sensor so that signal charge is discharged to the discharger, while a component having scattered inside the target is incident on the image sensor, causes the first accumulator to accumulate signal charge by setting the image sensor so that signal charge is not discharged to the discharger and signal charge is accumulated in the first accumulator, and causes the image sensor to generate first and second signals that are respectively based on signal charge accumulated in the first and second accumulators.

Abstract: A biological information detection device according to an aspect of the present disclosure includes: 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.
