Sharpness: “Sharpness” is the amount of high-frequency detail in the image. To adjust
sharpness, select Sharpness from the Picture menu and press ENTER . On your
external test pattern source, select a pattern like the one shown in Figure 4-5. Adjust as
needed, looking for white edges around the transitions from black to gray and
differently-sized lines in the “sweep” patterns at the top and bottom. Lower the
sharpness setting to eliminate them.

Noise Filter: To apply noise filtering to the input signal, select Noise Filter from the
Picture menu. The Noise Filter is useful for clearing up noisy images from 480i video
sources.
Use the left- or right-arrow buttons to select the desired amount of noise reduction,
keeping in mind that higher settings (which reduce high frequencies) may also “soften”
the image.
