A method for multi-frame blending includes the steps: obtaining at least two image frames of a scene. One of the image frames is associated with a shorter exposure time and a higher sensitivity and representing a reference image frame. At least one other of the image frames is associated with a longer exposure time and a lower sensitivity and representing at least one non-reference image frame. The method also includes blending the reference and non-reference image frames into a blended image such that (i) one or more motion regions of the blended image are based more on the reference image frame and (ii) one or more stationary regions of the blended image are based more on at least one non-reference image frame. 一种用于多帧混合的方法，包括：获得场景的多个图像帧，该多个图像帧包括利用较短曝光时间捕获的参考图像帧以及利用较长曝光时间捕获的多个非参考图像帧；调整参考图像帧的明度和颜色以匹配非参考图像帧；获得分别对应于该多个图像帧的多个运动映射；基于该多个运动映射，将参考图像帧与非参考图像帧混合成混合图像；以及对混合图像执行轮廓减少以减少混合图像中的轮廓伪影。
