Precaution for using the V shift and H shift with the lens shift block
When using the V shift and H shift with the lens shift block, be careful with the following.
The center position of the image is changed when zooming.
When the V shift or H shift of the lens shift block is used, the center position of image is deviated when
zooming.
The zoom ratio varies depending on the field angle (flat, scope, 16:9) of contents when zooming accord-
ing to the screen size. Therefore, it is required to correct the center position of image. The adjustment of
the image center position is performed using the touch panel (Refer to Section 5-8-3.). Since the adjust-
able tolerance in the vertical and horizontal directions varies depending on the field angle of contents, it
needs to be corrected in the following procedure.
.
When you want to perform the V shift, adjust the image position with flat (vertically longest field
angle), then correct the image center position with other field angles (scope, HD).
.
When you want to perform the H shift, adjust the image position with scope (horizontally longest field
angle), then correct the image center position with other field angles (flat, HD).
