Abstract
Apparatus and techniques for transferring image signals to readout electronics from image sensors. Electronic charges from multiple photosensitive elements are combined during and after transfer to detection electronics resulting in a greater signal to noise ratio. This enhanced signal to noise ratio provides the ability to make focus and exposure level measurements at lower light levels and often at greater speeds.
