Digital cameras are modern devices that capture still images or videos. To capture these images, they take in a range of inputs. These inputs can range from light to motion and even sound. Light is the most important input for a digital camera, as it determines the image quality, exposure, and color accuracy. Other inputs include motion sensors and sound sensors. Motion sensors help the camera recognize movement and sound sensors help the camera adjust its settings to match the environment. Additionally, digital cameras have different lenses and settings which can also affect the input, such as the focal length, aperture, and shutter speed. All of these inputs help create a beautiful and high-quality image.
