Abstract:
1. A method of movement correction in a digital camera having a sensor with a plurality of pixels, including a first, second, third and fourth pixel, wherein each pixel includes a photodiode and one or more shift transistors connected so as to shift charge to other pixels, the method comprising: dividing an exposure into two or more sub-exposures, including a first and a second sub-exposure; exposing the first and second pixels to electromagnetic energy during the first sub-exposure; accumulating charge on the photodiodes of the first and second pixels as a function of the electromagnetic energy incident on the first and second pixels during the first sub-exposure; shifting the accumulated charge from the photodiodes of the first and second pixels to the photodiodes of the third and fourth pixels, wherein shifting includes determining motion of the digital camera and shifting as a function of the motion of the digital camera; exposing the photodiodes in the third and fourth pixels to electromagnetic energy during the second sub-exposure; and accumulating additional charge on the photodiodes of the third and fourth pixels as a function of the electromagnetic energy incident of the photodiodes during the second sub-exposure.
