Abstract
An edge enhancer for enhancing edges within a video image, forms an edge enhancement signal of odd harmonics of a sinusoid representative of the edge content in an incoming signal. The edge enhancement signal may be added to a version of the incoming signal, thereby sharpening the edge in the incoming signal. This allows edges to be enhanced, increasing the image's rise-time without adding overshoot. Sharper edges are thus produced in much the same way as a square wave may be formed of odd harmonics of a sinusoid.
