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.

position for the current source.
