1. A method for displaying an image on a display apparatus of dot matrix type, the image having pixels arranged in ((M lines)×(N columns)), each pixel having color information, the display apparatus having elements arranged in ((P lines)×(Q columns), 1<P<M, 1<Q<N), comprising: separating the image into a first component and a second component based on a threshold, the first component having a spatial frequency not lower than the threshold, the second component having a spatial frequency lower than the threshold, the threshold being a ratio of the number of the elements to the number of the pixels; generating a plurality of first display components from the first component by first filter processing using a plurality of filters; generating a second display component from the second component by second filter processing; generating a plurality of sub-field images by composing each of the plurality of first display components with the second display component; and driving each element of the display apparatus using the color information of a pixel corresponding to the element in pixels of each of the plurality of sub-field images.
