A digital camera (or digicam for short) is a camera that takes video or still photographs,or both,digital by recording images via an eletronic image sensor.
Many compact digital stillcameras can record sound snd moving video as well as still photographs. Inthe Western market, digital cameras outsell their 35 mm film counterparts.
Digital camera can do things film camera cannot: displaying images on a screen immediately after they are recorded, storing thousands of images on a single small memory device,recording video with sound,and deleting images to free storage.
Digital cameras are incorporated into many devices ranging from PDAs and mobile phones (called camera phones) to vehicles. The Hubble Space Telescope and other astronomical device are essentially specialised digital cameras.
