Abstract:
To improve accuracy of distance measurement using a Z pixel having the same size as size of a visible light pixel. In a solid-state imaging apparatus, a visible light converting block includes a plurality of visible light converting units in which light receiving faces for receiving visible light are disposed and configured to generate electric charges in accordance with a light receiving amount of the received visible light, and a visible light electric charge holding unit configured to exclusively hold the electric charges respectively generated by the plurality of visible light converting units in periods different from each other. An infrared light converting block includes a plurality of infrared light converting units in which light receiving faces which have substantially the same size as size of the light receiving faces of the visible light converting units and which receive infrared light are disposed and configured to generate electric charges in accordance with a light receiving amount of the received infrared light, and an infrared light electric charge holding unit configured to collectively and simultaneously hold the electric charges respectively generated by the plurality of infrared light converting units.
