A digital camera is an electronic device that captures and stores images digitally, replacing traditional film-based cameras. It converts light into digital signals using an image sensor, allowing users to instantly view, edit, and share photos.

How Does a Digital Camera Work?
Light Enters the Lens – The camera lens gathers light and focuses it onto the sensor.

Image Sensor Captures Light – Either a CMOS (Complementary Metal-Oxide Semiconductor) or CCD (Charge-Coupled Device) sensor converts light into electrical signals.

Image Processor Enhances Quality – The camera processes the captured data, optimizing sharpness, color, and exposure.

Storage & Display – The final image is saved on a memory card and can be viewed on the camera’s LCD screen.
