METHOD AND APPARATUS FOR HIGH SPEED ACQUISITION OF MOVING IMAGES USING PULSED ILLUMINATION

摘要

A method of operating an image sensor with a continuously moving object is described. In this method, a time delay integration mode (TDI-mode) operation may be performed during an extended-time illumination pulse. During this TDI-mode operation, the charges stored by the pixels of the image sensor are shifted only in the first direction and track the image motion. Notably, the split-read operation is performed only during non-lighting. During this split-read operation, the first charges stored by the first pixels of the image sensor are shifted in the first direction and the second charges stored by the second pixels of the image sensor are simultaneously shifted in the second direction. , The second direction is opposite to the first direction.
