Abstract: Image authenticity verification is disclosed. In one example, in a verification unit, an image is captured by performing photoelectric conversion, an electronic signature is verified of the image output from an imaging element along with an electronic signature of the image, and the image is output in a case where verification of the electronic signature of the image is successful. Moreover, in the verification unit, the image is processed, an electronic signature is verified of a result of processing the image output from a processing unit that outputs a result of processing the image together with an electronic signature of the result of processing the image, and the result of processing the image is output in a case where verification of the electronic signature of the result of processing the image is successful.
