In one example, an imaging device includes a semiconductor substrate, a first pixel array, a second pixel array, and a control unit. In the first pixel array, a first light receiving pixel on the semiconductor substrate has a stacked structure of a first electrode, a photoelectric conversion layer, and a second electrode (80). It photoelectrically converts light in a first wavelength region including the visible light region. In the second pixel array, a second light receiving pixel is provided at a position overlapping the first light receiving pixel in a thickness direction of the semiconductor substrate. It photoelectrically converts light in a second wavelength region including the infrared light region. The control unit drives and controls the second pixel array based on a signal photoelectrically converted by the first pixel array.Type: ApplicationFiled: February 22, 2022Publication date: May 2, 2024Inventors: Hideaki Togashi, Kaori Takimoto, Masahiro Segami, Kei Nakagawa, Nobuhiro Kawai
