Sharpness: “Sharpness” is the amount of high-frequency detail in the image. To adjust sharpness, select Sharpness from the Picture Adjust 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.

Color Temp.: The Vision 70 has six memory settings for Color Temperature. Four of these settings are factory set to default as follows:
•0 -- Original lamp color temperature
•1 -- 5400 kelvins
•2 -- 6500 kelvins
•3 -- 8500 kelvins
•4 -- Custom
•5 -- Custom
Custom 4 and 5 memory are installer-adjustable and can be used to create custom settings. There are nine adjustable “white balance” parameters available for the Custom 4 and 5 settings (three each for red, green and blue). These are described later in this section; refer to Service on page 54.
