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.

Abstract: According to an embodiment, the representative brightness value of image data is determined through an analysis of the image data, the dimming value of a backlight is adjusted according to the representative brightness value, and the image data is converted so as to correspond to the adjusted dimming value such that pixels maintain original brightness. In order to simplify the image data conversion, a characteristic value may be generated according to the adjusted dimming value, and a gamma curve may be generated on the basis of the characteristic value, thereby converting the image data.
