Physics
  • A form of camera in which film is replaced by a semiconductor CCD array, which records the picture and stores it within the camera in a (usually) replaceable memory module.

Electronics and Electrical Engineering
  • A camera that records its image directly into digital memory using either a CCD sensor or a CMOS sensor. Both still and video images can be recorded, often by the same camera. Advanced digital cameras take still pictures by collecting a video stream while waiting for the shutter button to be pressed, and then use image processing techniques on frames from just before to just after the button press to produce the best possible image. All smartphone and most commercial and consumer-oriented cameras are digital. See also solid-state camera.
