Abstract
An image sensor includes a plurality of pixels, each of which has a photo storage cell, a sample-and-hold switch connected with one terminal of the photo storage cell, and a reset switch connected with the other terminal of the photo storage cell. Each of the pixels of the image sensor senses light and generates charge and stores the induced charge corresponding to the generated charge by controlling the switches, so as to achieve an electronic shutter function.
