The
horizontal position
of the image can be offset – that is moved to the left or right of
lens center, by adjusting the fully 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 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 2.4 for some illustrated
examples of horizontal offset.
See also Table 2.1 along with Figure 2.5 which shows the maximum horizontal offset of
a lens or 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.
