  • Focus and exposure measurement in digital camera using charge binning
    Patent number: 6812963
    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.
