    • Multiple images are captured where the exposure times for some of the images overlap and the images are spatially overlapped. Charge packets are transferred from one or more portions of pixels after particular integration periods, thereby enabling the portion or portions of pixels to begin another integration period while one or more other portions of pixels continue to integrate charge. Charge packets may be binned during readout of the images from the image sensor. Comparison of two or more images having different lengths of overlapping or non-overlapping exposure periods provides motion information. The multiple images can then be aligned to compensate for motion between the images and assembled into a combined image with an improved signal to noise ratio and reduced motion blur.
    • 捕获多个图像,其中一些图像的曝光时间重叠并且图像在空间上重叠。 在特定积分周期之后,从像素的一个或多个部分传送电荷包,从而使得像素的部分或部分开始另一个积分周期,同时像素的一个或多个其它部分继续积分电荷。 在从图像传感器读取图像期间,可以对充电分组进行分组。 具有不同长度的重叠或非重叠曝光周期的两个或多个图像的比较提供运动信息。 然后可以将多个图像对准以补偿图像之间的运动,并组合成具有改善的信噪比和减少的运动模糊的组合图像。
