Operation

Note	Brightness and Contrast controls are interactive. A change
	to one may require a subtle change to the other in order to
	achieve the optimum setting.

Color Saturation: To adjust the overall color intensity, select Color Saturation from the Main menu. Decrease this setting if colors are overly saturated; increase it if colors appear muted or washed out.

Color Tint: Tint or “hue” is the ratio of red to green in the color portion of the image. To adjust the tint, select Color Tint from the Main menu. Decrease this setting to shift the hue toward red; increase it to shift the hue toward green.

Note	Like the Brightness and Contrast controls, the color and tint
	controls are interactive. A change to one may require a subtle
	change to the other in order to achieve the optimum setting.

Sharpness: “Sharpness” is the amount of high-frequency detail in the image. To adjust this, select Sharpness from the Main menu and press ENTER. On your external test pattern source, select a pattern like the one shown in Figure 4-5.

Figure 4-5. Typical Test Pattern for Adjusting Sharpness

•Sharpness (Simple Mode): 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.
