Method and apparatus for fast acquisition of moving images using pulsed illumination

摘要

A method of operating an image sensor using a continuously moving object is described. In this method, a time delay integration mode (TDI mode) operation can be performed during a long irradiation pulse. During this TDI mode operation, the charge stored by the image sensor pixels is shifted only in the first direction to track the movement of the image. In particular, the divided readout operation is performed only during non-irradiation. During this split readout operation, the first charge stored by the first pixel of the image sensor is shifted in the first direction, and the second charge stored by the second pixel of the image sensor is Shifted simultaneously in the second direction, which is the opposite of the one direction.
