Abstract: Certain embodiments relate to an electronic device and a method for changing gamma values and may include determining a target gamma curve related to first image data to be displayed by a display panel, receiving a request for switching a scan rate of the display panel from a first frequency to a second frequency, determining a gamma offset and an offset margin in response to reception of the request, determining a limit gamma curve generated by applying the gamma offset and the offset margin to the first gamma curve, generating second image data by correcting the first image data, based on a difference value between the limit gamma curve and the target gamma curve to map the first image data to the target gamma curve, and driving the display panel, based on the second image data and the limit gamma curve. This document may further include various other embodiments.
