Abstract
The disclosure provides an image processing device and method capable of removing a halo artifact and increasing contrast enhancement effect when enhancing the contrast of an image. The image processing method includes obtaining a first blurring image by performing interpolation based on a representative value of each of blocks, having a predetermined size, of a previous frame image; obtaining a second blurring image in which boundary information is restored, through a weighted sum of a current frame image and the first blurring image; and performing contrast enhancement on the current frame image by using a difference image between the second blurring image and the current frame image.
