Abstract
An image sensor includes an array of pixels arranged into two or more subarrays and each subarray captures charge; and an output charge-coupled device that receives charge from the array of pixels; wherein the output charge-coupled device is divided into substantially two equal first and second portions in which either one portion receives charge from only one subarray or both portions receive charge respectively from a subarray, and the first portion of the charge-coupled device is a charge-multiplying charge-coupled device in which charge is amplified, and the second portion of the charge-coupled device does not amplify charge.
