Abstract:
1. An image pickup apparatus comprising: an image pickup region of a solid-state image pickup device in which a plurality of pixels are arranged, each pixel including a plurality of photoelectric conversion portions disposed in the depth direction of a semiconductor; an imaging signal processing circuit including a gain variable amplifier unit that amplifies an image signal output from the solid-state image pickup device and a gain correction circuit that collects a gain value of the gain variable amplifier unit; and a filter which is disposed on the incident side of the image pickup region and which has a characteristic wherein the transmittance of light in the visible wavelength region decreases as the wavelength of light becomes longer, wherein the transmittance is at least 90% at a wavelength of 400 nm and continuously decreases from 400 nm to 700 nm so that with any increase in the wavelength in the range from 400 nm to 700 nm the transmittance decreases.
