A digital camera, an electronic device that digitally records photographs, eschews traditional film-based cameras. It operates through an image sensor like a Charge-Coupled Device (CCD) or a Complementary Metal-Oxide-Semiconductor (CMOS), which logs light data when a photo is snapped. This information is subsequently processed and saved in digital memory, facilitating immediate viewing and editing. Digital cameras are available in a range of styles, from compact and action cameras to advanced equipment used in scientific and military contexts. They provide professional photography features, such as high-definition image quality and diverse image capture techniques. With the rise of smartphones, digital cameras have become a ubiquitous feature, empowering everyone to document and share their experiences.

Digital camera (Wikipedia)

A digital camera, also called a digicam, is a camera that captures photographs in digital memory. Most cameras produced today are digital, 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 (which are still available). High-end, high-definition dedicated cameras are still commonly used by professionals and those who desire to take higher-quality photographs.

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. The diaphragm and shutter admit a controlled amount of light to the image, 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 kinds of image editing.
