A digital camera is an electronic device that captures still images or moving images digitally, as opposed to film-based photography. It consists of a lens, an image sensor, and a processing unit that converts the captured image into a digital format. Digital cameras have largely replaced traditional film cameras due to their convenience, cost-effectiveness, and the ability to instantly review and share images.

There are several types of digital cameras, including compact cameras, bridge cameras, and single-lens reflex (SLR) cameras. Compact cameras are small and portable, making them ideal for casual photography. Bridge cameras offer a balance between compact size and advanced features, while SLR cameras provide professional-grade image quality and manual controls.

Digital cameras use various image sensors, such as CMOS and CCD, to capture light and convert it into electrical signals. The resolution of a digital camera is typically measured in megapixels, with higher resolutions resulting in sharper images. Other important features include autofocus systems, image stabilization, and video recording capabilities.

The images captured by a digital camera are stored in memory cards, which can be easily transferred to computers for editing and sharing. Digital cameras have revolutionized photography by making it more accessible and convenient, allowing users to capture and share their memories instantly.
