Abstract: Provided is an imaging apparatus including an imaging element section, an imaging optical system, a transmission/block section, an actuator, and an output section. The imaging element section includes a plurality of pixels, and the imaging optical system forms an image on the imaging element section, the image being formed by an electromagnetic wave from the outside.
