The horizontal position of the image can also be offset –
that is, moved to the left or right of lens center, by
adjusting the fully motorized lens mount system. The
amount of horizontal offset available depends on the lens
installed and if the image has already been vertically
offset. Horizontal offset can also be expressed as the
percent of half the image width – the number of pixels of
shift to one side of lens center. Refer to Figure 2.3 for
some illustrated examples of horizontal offset.
See also Table 2.1 along with Figure 2.9 which shows the
maximum horizontal offset of a lens; alternatively, how
much of your projected image will appear to one side of
lens center if the maximum horizontal offset is applied
using that lens.
