A digital camera is a device that captures photographs and stores them in a digital format instead of using traditional photographic film. It uses an image sensor, such as a CCD (Charge-Coupled Device) or CMOS (Complementary Metal-Oxide Semiconductor), to convert light into electronic signals, which are then processed into digital images. These images are stored electronically on memory devices like internal flash memory or removable memory cards, allowing for instant viewing, editing, and sharing
. Unlike film cameras, digital cameras can display images immediately after capture on a screen, and users can delete or store multiple photos without needing physical film. Many digital cameras also record videos with sound and offer features like cropping and stitching images. They come in various types, including compact point-and-shoot cameras, digital single-lens reflex (DSLR) cameras, mirrorless cameras, and action cameras. DSLRs, for example, use a reflex mirror and a large sensor to provide high-quality images and interchangeable lenses for versatility
. Digital cameras are commonly measured by their resolution in megapixels, which indicates the detail and size of the images they produce. Higher megapixels can be useful for large prints or cropping but are not the sole factor determining image quality
. In summary, a digital camera is an electronic device that captures light through a lens and sensor, converts it into digital data, and stores it for immediate use, making photography more accessible and flexible compared to traditional film cameras
