Abstract
An information handling system includes a display device and a processor. The display device outputs pixels associated with a text font. The processor converts red, green, blue (RGB) pixels to image perspective transformation (IPT) pixels. The processor further sharpens one or more of the IPT pixels that do not have color. The sharpening of the one or more of the IPT pixels identifies edges of the text font and defines widths of the text font. The processor corrects edge overshoot and edge undershoot created by a digital filter. The edge overshoot and the edge undershoot are corrected for each IPT pixel associated with the text edges. The processor also reduces noise enhancement in the sharpened IPT pixels, retains grey text portions of each of the sharpened IPT pixels, and converts the IPT pixels to new RGB pixels. The processor outputs the new RGB pixels to the display device.
