An imaging apparatus includes a light source that includes a diffusion plate and, in operation, emits, toward a subject, pulsed light that diverges; a photodetector that includes a photoelectric converter that, in operation, receives light from the subject and converts the light to an electric charge and an electric charge accumulator that, in operation, accumulates the electric charge, and, in operation, generates an electric signal based on the accumulated electric charge; and a control circuit that, in operation, controls the light source and the photodetector. The control circuit, in operation, causes the electric charge accumulator to start accumulating the electric charge when a period of time has passed after the control circuit has caused the light source to start emitting the pulsed light, and causes the electric charge accumulator to accumulate the electric charge corresponding to a component, among the light from the subject, that is scattered inside the subject. 1. An imaging apparatus , comprising:a light source that includes a diffusion plate and, in operation, emits pulsed light toward a subject, the pulsed light diverging at a divergence angle greater than 0 degrees;a photodetector including a photoelectric converter that, in operation, receives light from the subject and converts the light to an electric charge, and an electric charge accumulator that, in operation, accumulates the electric charge, the photodetector, in operation, generating an electric signal based on the electric charge accumulated in the electric charge accumulator; anda control circuit that, in operation, controls the light source and the photodetector, wherein:the control circuit, in operation, causes the electric charge accumulator to start accumulating the electric charge when a predetermined period of time has passed after the control circuit has caused the light source to start emitting the pulsed light, and thus causes the electric charge accumulator to accumulate the ...
