value of 23. Value is calculated by multiplying the percentage by the 

constant 255 (value = 255 x percent).

●

     

If you choose Percent, the numbers represent the percentage of the 

maximum intensity of the pixel. For instance, a G value of 35% 

indicates that the sampling size selected has a green color value of 

35 percent intensity (out of 100 percent). Percent is calculated by 

dividing the constant 255 by the value (percent = 255 ÷ value).

This determines the expanse of color information to be made available. For 

instance, if you choose 5 x 5 as your sample area, this means your RGB 

values will represent color information for a 5-pixel by 5-pixel area. If you 

choose 1 x 1, the color information pertains to a single pixel — the one 

shown in the middle of the Pixel Display.

The Color Output Meter is useful if you wish to adjust the shadow and 

highlight points of an image.

As you pass over a point in the image, the Color Output Meter will show 

the appropriate RGB values of that point in the image. The significance of 

the numbers is explained below.

●

     

There are two numbers shown in the Color Output Meter. The first 

number represents the raw color data taken by the scanner; the 

second number represents the resulting value after color correction 

or image enhancement is applied to the image.

●

     

The values can be anywhere from 0 to 255, with 0 as the black point, 

255 as pure white, and all other values in between corresponds to 

shades of varying degrees between black and white.

●

     

The values as a whole represent color information for the sample size 

selected in the Color Meter Options button (discussed below). For 

instance, if you chose 3 x 3 as your sample size and your R value 

reads 23, that shows your red value of 23 is the average of a 3-pixel 

by 3-pixel area.
