The Imaging Chain
The imaging chain of the camera are made up of four components: the lens, the iris, the shutter, and the image sensor.
- Lens: Determines the field of view, or what the camera "sees". The lens is mounted on the front of the camera and is designed to capture and manipulate the light reflected from objects in the camera's line of sight.
- Iris: Regulates the intensity of exposure. An adjustable plastic or metal diaphragm that regulates the amount of light striking the image sensor.
- Shutter: Regulates the time of exposure. A movable curtain, plate, or other device that controls the amount of time the image sensor is exposed to light.
- Image Sensor: Captures light and converts it into digital signal. A small electronic chip used to register the intensity and color of light. Also the digital equivalent of "film".
