Abstract: A method and an apparatus for detecting and removing a false contour, a method and an apparatus for verifying whether a pixel is included in a contour, and a method and an apparatus for calculating simplicity are provided. The method for detecting and removing the false contour includes: verifying whether a pixel of an input video is included in a contour; calculating simplicity of the pixel; determining whether the pixel is included in a false contour based on the simplicity and based on whether the pixel is included in the contour; and removing the false contour from the input video via smoothing with respect to the false contour.

Abstract: Embodiments of the disclosure relate to a compensation device of luminance uniformity and a controlling method thereof, more particularly, to a technology of predicting a level of maximum luminance value that is changed in compensating luminance uniformity of an image displayed on a display apparatus and providing it to a user.
A compensation device of luminance uniformity according to an embodiment includes a data acquirer configured to acquire a luminance value of an image displayed on a display apparatus; a controller configured to determine a maximum luminance value and a minimum luminance value among the acquired luminance values, and determine luminance uniformity of the minimum luminance value based on the maximum luminance value, and determine a change amount of the maximum luminance value to be adjusted in order to change the determined luminance uniformity; and a display configured to display the change amount of the maximum luminance value adjusted to change the luminance uniformity, and the luminance uniformity that is changed in response to the change amount of the maximum luminance value.
