A digital camera is a camera that takes video or still photographs, or both, digitally by recording images on a light-sensitive sensor.Many compact digital still cameras can record sound and moving video as well as still photographs. In the Western market, digital cameras outsell their 35 mm film counterparts.Digital cameras can include features that are not found in film cameras, such as displaying an image on the camera’s screen immediately after it is recorded, the capacity to take thousands of images on a single small memory device, the ability to record video with sound, the ability to edit images, and deletion of images allowing re-use of the storage they occupied.
The term digital still camera (DSC) usually implies a live-preview digital camera, which uses an electronic screen, usually a rear-mounted liquid crystal display, as the principal means of framing and previewing before taking the photograph, and for viewing stored photographs. All use either a charge-coupled device (CCD) or a CMOS image sensor to sense the light intensities across the focal plane.
Compact cameras are designed to be small and portable; the smallest are described as subcompacts. Compact cameras are usually designed to be easy to use.
Bridge or SLR-like cameras are higher-end live-preview cameras that physically resemble DSLRs and share with them some advanced features, but share with compacts the live-preview design and small sensor sizes.
