Abstract
An image fusion method for removing ghost artifacts is provided. The method includes: determining a first fusion weight of a reference pixel in a reference frame, wherein the coordinates of the reference pixel are the same as the coordinates of one of input pixels included in an input frame; determining a reference brightness parameter according to values of all channels of the reference pixel; determining an input brightness parameter according to values of all channels of the input pixel; determining a ghost weight according to an amount that the brightness parameter ratio of the input brightness parameter and the reference brightness parameter deviates from a reasonable range; determining a fusion weight according to the first fusion weight and the ghost weight; and fusing the reference pixel with the input pixel according to the fusion weight to generate a fused pixel in a fused frame.
