The PlayStation Camera is an optional motion sensing accessory for PlayStation 4. It includes two 1280×800 pixel cameras with lenses having an aperture of f/2.0, with 30 cm focusing distance, and an 85° field of view. The dual camera setup allows for different modes of operation, depending on the target application. The two cameras can be used together for depth-sensing of objects in its field of vision, akin to the Xbox's Kinect peripheral. Alternatively, one of the cameras can be used for generating the video image, with the other used for motion tracking. It is the successor to the PlayStation Eye for the PlayStation 3, which was released in 2007.
