Abstract
The present invention provides a motion ghost resistant HDR image generation method and a portable terminal. A normally exposed image and an underexposed image are mapped to an overexposed image and are fused in the overexposed image, such that the values of the underexposed image are more considered to be used in the fused image in a bright place and the values of the overexposed image are more considered to be used in a dark place; therefore, both the dark place and bright place have abundant information and a motion ghost resistant HDR image is finally generated, thus improving the visual effect of a ghost-removed high-dynamic range image.
