Digital Image Stabilization

The ongoing development and miniaturization of consumer devices that have image acquisition capabilities increases the need for robust and efficient image stabilization solutions. The need is driven by two main factors: (i) the difficulty to avoid unwanted camera motion when using a small hand-held device (like a camera phone), and (ii) the need for longer integration times due to the small pixel area resulted from the miniaturization of the image sensors in conjunction with the increase in image resolution. The smaller the pixel area the less photons/second could be captured by the pixel such that a longer integration time is needed for good results.
