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. The transmission/block section transmits and blocks the electromagnetic wave to/against the imaging element section, the transmission/block section being disposed at an aperture stop position in the imaging optical system. The actuator drives the transmission/block section to move back and forth to be changed in state between transmission and blocking. The output section produces an image signal output being differential signaling between a pixel output from the imaging element section when the transmission/block section is in the transmission state, and a pixel output from the imaging element section when it is in the blocking state.
