Imaging method and system |
摘要 |
A method and system for accurately imaging scenes having large brightness variations. If a particular object in the scene is of interest, the imager exposure setting is adjusted based on the brightness of that object. For high dynamic range imaging of an entire scene, two imagers with different viewpoints and exposure settings are used, or the exposure setting of a single imager is varied as multiple images are captured. An optical flow technique can be used to track and image moving objects, or a video sequence can be generated by selectively updating only those pixels whose brightnesses are within the preferred brightness range of the imager.
