Figure 2.3. Lens Vertical Offsets
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 through software. 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 percentage 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.
