Digital Cinema Dual System
(6) Registration of function for Scope image
1) Call the setting for Scope in the main projector registered in 2-(4)-7) from the function memory.
2) Call the setting for Scope in the sub-projector registered in 3-(4)-3) from the function memory.
3) Project the Convergence Adjust Scope test pattern from the main projector and sub-projector.
4) Adjust the V shift of “Electric Shift” of the sub-projector so that the center of image in the verti-
cal direction is aligned with the center of screen.
5) Check that the distance between both sides (right and left) of the Scope image projected on the
3D filter of the sub-projector and the filter frame is within the range of specification. (Refer to
Section 2-8-4.) If it is out of the range, adjust the distance by moving the filter bracket back and
forth.
6) Adjust the lens focus of the sub-projector.
7) Set the test pattern of the sub-projector to OFF.
8) Register by overwriting the setting in the function memory for Scope in the sub-projector.
4. Perform the adjustment using “Distortion Adjust”. Save the adjustment results in the function memory.
Perform the further adjustment of the image of the two projectors using the electric image distortion
correction function.
.
Basically, perform the correction of the sub-projector using the main projector as a reference.
.
Perform the correction of the main projector only when the adjustment is not enough only by the cor-
rection of the sub-projector.
.
Specify the CALIBRATION mode of the calibration camera (refer to Section 6) as follows depending
on which projector has been corrected.
Corrected sub-projector only: STATIC mode
Corrected both projectors:
TRACE mode
*
: If the image cannot be adjusted even if both projectors were corrected, perform steps 1 to 3 again.
(1) Scope image adjustment
1) Call the function memory for Scope to both projectors.
2) Project the Convergence Adjust Scope test pattern from both projectors.
3) Adjust the image with “Distortion Adjust”. (Refer to “5-8-5. Overlaying the Images of Two
Projectors”.)
4) Register both projectors in the function memory of Scope.
(2) Flat image adjustment
1) Call the function memory for Flat to both projectors.
2) Project the Convergence Adjust Flat test pattern from both projectors.
3) Adjust the image with “Distortion Adjust” and register both projectors in the function memory of
Flat.
5. Adjustment using the calibration camera
Refer to Section 6.
