Digital cameras can perform equipment film cameras cannot: display images on a panel directly after they are record, storing thousands of images on a only small memory device, and deleting images to without charge storage space. The mainstream, including mainly compact cameras, can record moving video by sound as well as still photographs. Some can crop and stitch pictures and perform extra elementary image editing. Some have a GPS receiver built in, and can produce Geotagged photographs.
The optical system works the equal as in movie cameras, naturally use a lens by a variable diaphragm to focus light onto an image pickup device. The diaphragm and shutter admit the correct amount of light to the imager, very soon as by film however the image pickup device is electronic rather than chemical. mainly digicams, apart from camera phones and a little specialized types, have a standard tripod screw.
Digital cameras are incorporated into a lot of strategy ranging from PDAs and mobile phones (called camera phones) to vehicles. The Hubble Space Telescope and other astronomical devices are essentially specialized digital cameras
