MONITORING CAMERA SYSTEM, IMAGING DEVICE, AND VIDEO DISPLAY DEVICE

This relates to an imaging device in which the necessary monitoring of an individual can be realized, while still maintaining protection of an individual's privacy. The imaging device includes an encryption key storage unit in which encryption key data is stored for an individual, an object judging unit operable to judge whether or not the captured video is of the individual, and a limited-capture video generation unit operable to (i) convert a part of the captured video that includes the individual into encrypted video, (ii) generate limited-capture video, which includes the encrypted video, when said object judging unit judges that the captured video includes the individual, and (iii) output the captured video, which does not include the encrypted video, when said object judging unit judges that the captured video does not include the individual.
