A digital camera captures still images or videos and stores them in a digital format. Unlike traditional film cameras, digital cameras use an electronic image sensor to capture light and convert it into digital . This allows users to instantly view, edit, and share images without the need for development. Digital cameras are utilized for both amateur and professional photography, providing the ability to capture high-resolution images and often record video in HD or even resolution.
The key components of digital cameras include the lens, which focuses light onto the image sensor, and the image sensor itself, which converts light into an electrical signal. The two most common types of sensors are (Charge-Coupled Device) and (Complementary Metal-Oxide-Semiconductor). Additionally, digital cameras have a viewfinder or display that is used to frame and review images, while storage is typically on memory cards such as or CompactFlash. The processor in the camera handles the conversion of raw data from the sensor into a viewable image format, allowing for the storage and sharing of images.
Digital cameras come with several advantages, including the immediate review of captured images, allowing users to determine if retakes are necessary. They also offer storage efficiency, as thousands of images can be stored on a single memory , and facilitate easy sharing of digital images via the internet. However, there are disadvantages as well, such as shorter battery life compared to traditional film cameras and potential variations in image quality among different models, particularly in cheaper cameras.
