Pocket Camera is a unique Game Boy title released in Japan (with a revision A).  Unlike most games, it acted like a virtual camera, allowing players to take and save pictures of anything displayed on the Game Boy screen.  Gameplay likely involved simple controls for positioning and capturing images, with a limited amount of space for storage.  The game's novelty lies in its functionality, offering a creative and rudimentary form of digital photography at the time.  The developer and publisher information would require more research.
