A digital camera is a camera that captures photographs in digital memory. Most cameras produced today are digital,[1] largely replacing those that capture images on photographic film. Digital cameras are now widely incorporated into mobile devices like smartphones with the same or more capabilities and features of dedicated cameras. While there are still dedicated digital cameras, many more cameras are now incorporated into mobile devices like smartphones.[2] High-end, high-definition dedicated cameras are still commonly used by professionals and those who desire to take higher-quality photographs.[3]
Digital and digital movie cameras share an optical system, typically using a lens with a variable diaphragm to focus light onto an image pickup device.[4] The diaphragm and shutter admit the correct amount of light to the image, just as with film but the image pickup device is electronic rather than chemical. Digital cameras can display images on a screen immediately after being recorded, and store and delete images from memory. Other capabilities of most modern digital cameras consists of recording videos with sound, cropping, and stitching photos all within camera.[5]
