Abstract: The display technologies relate to a method and computer-readable medium for displaying image and to a display device configured to perform the method for displaying image. The image display method includes acquiring an image for display in an nth frame on a display screen; detecting a first sub-image and a second sub-image within the image, a resolution of the first sub-image being higher than a resolution of the second sub-image; comparing the first sub-image in the nth frame with a corresponding sub-image in an (n−1)th frame; and refreshing a localized area of the display screen positionally corresponding to the first sub-image to display an interpolated sub-image in the localized area.
