The Invention
UW-Madison researchers have developed a method that dynamically changes exposure times on a per pixel basis in response to changes in the scene. The method relies on taking a series of images, then (on chip or in post processing) applying statistical changepoint detection to estimate times that pixels have changed value, indicating motion or a change in lighting. Between detected changepoints the images can be averaged to create a sharp image that can be used to find scene motion, or motion can be directly inferred from the changepoints. This technique particularly is helpful in low illumination or high-speed situations where it is important to have as long an exposure time as possible without blurring.
