1. A display apparatus for displaying an image on a display device which includes rows of pixels, each pixel composed of three sub-pixels that align in a lengthwise direction of the pixel rows and emit light of three primary colors respectively, the display apparatus comprising:

  • a front image storage unit operable to store color values of sub-pixels that constitute a front image to be displayed on the display device;

    a calculation unit operable to calculate a dissimilarity level of a target sub-pixel to one or more sub-pixels that are adjacent to the target sub-pixel in the lengthwise direction of the pixel rows, from color values of first-target-range sub-pixels composed of the target sub-pixel and the one or more adjacent sub-pixels stored in the front image storage unit;

    a superimposing unit operable to generate, from color values of the front image stored in the front image storage unit and color values of an image currently displayed on the display device, color values of sub-pixels constituting a composite image of the front image and the currently displayed image;

    a filtering unit operable to smooth out color values of second-target-range sub-pixels of the composite image that correspond to the first-target-range sub-pixels, by assigning weights, which are determined in accordance with the dissimilarity level, to the second-target-range sub-pixels; and

    a displaying unit operable to display the composite image based on the color values thereof after the smoothing out.
