The present invention relates to a digital image signal processing method and apparatus, and more particularly, to an edge compensation method and apparatus of an image signal capable of improving the quality of an image in instruments performing a digital image signal process. An edge compensation method of a digital image signal processing system includes the steps of generating a luminance signal from a luminance matrix by receiving digital red, green and blue R, G and B image signals, generating a vertical edge signal in real-time by sequentially delaying the luminance signal in units of one horizontal line, generating a horizontal edge signal in real-time by sequentially delaying the luminance signal delayed in units of one horizontal line during a given time period, generating a composite image edge signal by adding the vertical edge signal to the horizontal edge signal, and outputting an edge-compensated luminance signal by adding the composite image edge signal to an uncompensated luminance signal.
