Abstract: In an image processing method that converts image data into output data by performing tone mapping, an edge of an image represented by the image data is determined, a first tone mapping operation is performed on first image data included in the image data, where the first image data represent a first portion of the image not including the edge, whether a gray level of second image data is within a predetermined gray range is determined, where the second image data represent a second portion of the image including the edge, a second tone mapping operation is performed on the second image data when the gray level of the second image data is within the gray range, and the first tone mapping operation is performed on the second image data when the gray level of the second image data is not within the gray range.

Abstract: A method for driving a display panel includes obtaining a first grayscale histogram based on input image data, generating a gamma curve by selectively changing an initial gamma curve based on at least one of the first grayscale histogram or a predetermined power mode, and generating output image data based on the input image data and the gamma curve. When the gamma curve is different from the initial gamma curve, the method includes changing an operating frequency of the display panel from a first frequency to a second frequency. The second frequency is lower than the first frequency. The operating frequency is changed to display an image frame corresponding to the output image data based on the second frequency.
