Abstract:
A method and an apparatus for correcting a multi-exposure motion image are disclosed, where the method includes determining a luminance mapping function, where the luminance mapping function is a luminance mapping relationship between a reference frame and multiple extended frames; mapping a luminance of an extended frame by using the luminance mapping relationship 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 according to the global motion vector to obtain a first extended frame after correction; 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.
