Abstract
A method is provided for displaying an original high-resolution digital color image on a low-resolution color dot-matrix display such as a liquid crystal display (LCD). Generally speaking, the method is used to display an original digital color image of a resolution of A×B on a color display of a resolution of C×D, where A, B, C, D are positive integer numbers and A>C and B>D. The first step is to group the pixels of the original digital color image in a unit of E into a plurality of groups equal in number to the pixels in the color display, where E is a ratio value obtained by rounding up the result of the division of A by C to the nearest integer number. Each of the groups is matched to one pixel in the color display. From each group, a set of RGB values is respectively extracted from selected pixels in the group, in a featured RGB extraction method. The final step is then to drive each pixel in the color display to display a specific color corresponding to the assigned RGB values. This process is repeated until all the groups in the same horizontal line and all the horizontal lines in the original digital color image are matched to the pixels in the LCD. This method allows the resulting image on the low-resolution LCD to have high fidelity to the original high-resolution image.
