Abstract: According to one embodiment, a camera module includes an imaging device, a liquid crystal panel and a lens. The liquid crystal panel includes first to fourth areas, a liquid crystal layer, and a driver. A size of the third and fourth areas is smaller than a size of the first and second areas. A first distance to a subject is calculated based on first and second images. The first image is based on light transmitted through the first area. The second image is based on light transmitted through the second area. A second distance to the subject is calculated based on third and fourth images. The third image is based on light transmitted through the third area. The fourth image is based on light transmitted through the fourth area.

Abstract: According to one embodiment, an electronic device includes a liquid crystal panel and a camera. The liquid crystal panel includes a display area, an incident light control area, and an emitted light control area. The camera includes a light-entering surface and a light source. The liquid crystal panel is configured to selectively transmit visible light emitted from the light source in the emitted light control area and to selectively transmit visible light from outside in order to cause visible light to enter the camera from the outside in the incident light control area.
