noun

• (photography) A device for taking still or moving pictures or photographs.
  "The single-imaging optic of the mammalian eye offers some distinct visual advantages. Such lenses can take in photons from a wide range of angles, increasing light sensitivity. They also have high spatial resolution, resolving incoming images in minute detail. It’s therefore not surprising that most cameras mimic this arrangement."
• (computer graphics, video games) The viewpoint in a three-dimensional game or simulation.
  "If you're building a third-person game with enclosed or tight spaces, try to figure out up front what camera problems you will likely encounter. Use this identification process to influence the early building process."
