摘要： A method of controlling a display apparatus displaying a plurality of frame images sequentially, the method includes detecting whether the sequential frame images in the plurality of frame images have a blurry image area or a non-blurry image area, and interposing an intermediate frame image between the respective sequential frame images by inserting an image having pixel values lower than pixel values of the sequential frame images in the blurry image area, and by inserting an image having either the pixel value of one of the sequential frame images, or an average pixel value of the sequential frame images in the non-blurry image area. The method of controlling a display apparatus eliminates a motion-blur effect without deteriorating brightness.
