The horizontal position of the image can also be offset; that is moved to the left or right of optical center, by
adjusting the motorized lens mount. The amount of horizontal offset available depends on the lens installed
and if the image has already been vertically offset. Horizontal offset can be expressed as the percent of half the
image width or the number of pixels of shift to one side of lens center. Table 2.4, Table 2.5 and Table 2.6 each
show the horizontal offset of a lens type. See Figure 2-2 Horizontal Offset Examples.
