A digital camera is a sophisticated electronic device designed to capture, store, and sometimes manipulate digital images. Unlike traditional film cameras, which use photographic film to record images, digital cameras use an image sensor to convert light into digital data. These cameras have become increasingly popular due to their convenience, versatility, and the ability to instantly view and share photos.
At the heart of a digital camera is its image sensor, typically a charged-coupled device (CCD) or a complementary metal-oxide-semiconductor (CMOS) sensor. When light enters the camera through the lens, it strikes the sensor, where individual pixels convert the light into electrical signals. These signals are then processed by the camera's internal circuitry and converted into a digital image file.
Digital cameras come in various shapes, sizes, and configurations to suit different needs and preferences. They range from compact point-and-shoot cameras, which are ideal for everyday photography, to advanced digital single-lens reflex (DSLR) or mirrorless cameras, favored by professional photographers for their superior image quality and manual control options.
