Abstract:
1. An image pickup apparatus comprising: a light source for emitting first-component light in a visible-light spectrum, and second-component light having an excitation wavelength of an infrared-fluorescent substance, toward a subject that includes the infrared-fluorescent substance for emitting infrared fluorescent light; an optical filter for transmitting the infrared fluorescent light and a spectral component that corresponds to the first-component light among light from the subject, and preventing transmission of a spectral component that corresponds to the second-component light; a solid-state image sensor capable of capturing a visible-light image and an infrared image on the basis of transmitted light of the optical filter; and a signal processing circuit for processing a signal read from each photoreceptor pixel of the solid-state image sensor and generating an image signal that represents a composite image based on the visible-light image and the infrared image.
