Abstract:
A driving controller includes a logo detector. The logo detector includes a histogram extractor which receives input image data and extracts a first histogram from logo area data of the input image data, a first histogram regenerator electrically connected to the histogram extractor and configured to receive the first histogram from the histogram extractor to generate a second histogram based on the first histogram and a logo map determiner electrically connected to the histogram extractor and the first histogram regenerator, and configure to select one of the first histogram and the second histogram to generate a first logo map. The driving controller is configured to compensate the logo area data of the input image data using the first logo map.
