ABSTRACT:
An apparatus and method are disclosed for displaying an image having high frequency components. The image is displayed on a display device that includes a plurality of display elements arranged in both horizontal and vertical directions. The display elements represent colors, such as red, green and blue. A pixel data generator generates for each display element first pixel data corresponding to the luminance levels of red, green and blue colors in the image. A smoothing filter eliminates false colors in the image by applying weighting coefficients to the first pixel data to modify the luminance levels of the first pixel data, thereby producing second pixel data having second color element data corresponding to luminance levels of the respective colors. Each display element of the display is driven in accordance with the second color element data.
