Detailed explanation-1: -A digital camera is an input device that captures images (and sometimes video) digitally. Digital cameras use an image sensor chip to capture the image. However, it can also be used as an output device.
Detailed explanation-2: -Video input devices are used to digitize images or video from the outside world into the computer. The information can be stored in a multitude of formats depending on the user’s requirement. Many video input devices use a camera sensor.
Detailed explanation-3: -Inside a digital camera is an array of light sensors. When a picture is taken the array of sensors is used to input the image.
