摘要
Systems and methods described herein can compensate for aberrations produced by a moving object in an image captured using a flash. In some embodiments, a method includes capturing a first image at time t−Δt1, where Δt1 represents the time difference between capturing the first image and capturing the second image, capturing the second image at a time t, the second image captured using a flash. The method also includes capturing a third image at a time t+Δt2, where Δt2 represents the time difference between capturing the second image and capturing the third image, determining motion information of an object that is depicted in the first, second and third image, and modifying at least one portion of the second image using the motion information and a portion of the first image, a portion of the third image, or a portion of the first image and a portion of the third image.
