Claim Text:
1. A method for correcting a multi-exposure motion image, comprising: mapping a luminance of an extended frame using a luminance mapping relationship between a reference frame and multiple extended frames to obtain a virtual frame; calculating a global motion vector between the virtual frame and the reference frame; correcting a pixel of the extended frame in a pointer offset manner to obtain a first extended frame after correction when the global motion vector comprises a translational motion vector; correcting the pixel of the extended frame in an interpolation manner to obtain the first extended frame after correction when the global motion vector comprises the translational motion vector and a rotational motion vector; detecting a pixel of the first extended frame according to the reference frame to obtain a local error pixel of the first extended frame; and correcting a luminance of the local error pixel of the first extended frame to obtain a second extended frame after correction.
