<P> Digital and movie cameras share an optical system , typically using a lens with a variable diaphragm to focus light onto an image pickup device . The diaphragm and shutter admit the correct amount of light to the imager , just as with film but the image pickup device is electronic rather than chemical . However , unlike film cameras , digital cameras can display images on a screen immediately after being recorded , and store and delete images from memory . Many digital cameras can also record moving videos with sound . Some digital cameras can crop and stitch pictures and perform other elementary image editing . </P>
