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 50 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 56.
The Sharpness setting has no effect if the Video Filter (described on
page 54) is set to 0.
