Appendix 2
LEARNING A REFERENCE
Adjust one Reference Source with perfect geometry. This source can have
either horizontal or vertical frequency. Remember that other sources will have
the same geometry as this Reference Source. This means that if a source has
4:3 aspect ratio, all sources will be adjusted with a 4:3 aspect ratio and the same
horizontal and vertical amplitudes.
Follow the steps below to select:
Enter in the Adjustment Mode and select EYE-Q
TM
by pushing up or down
keys of the control disc. Now select SETUP using the up or down keys,
finally select LEARN REFERENCE.
EYE-Q
TM
will now project the Reference Source with horizontal green line insert-
ed at the top region and a horizontal green line inserted at the bottom region of
the image.
Pushing the up or down keys of the control disc adjust the horizontal green
line at the top until it matches the top edge of the Reference Source per-
fectly, then press <ENTER>.
Using the up or down keys of the control disc adjust the horizontal green
line at the bottom until it matches the bottom edge of the Reference Source
perfectly, then press <ENTER>.
Now EYE-Q
TM
projects the Reference Source with a vertical green line inserted
at the left and a vertical green line inserted at the right.
Pushing the up or down keys of the control disc changes the position of the
vertical green lines simultaneously; they are being shifted symmetrically
inward and outward with respect to the scan of the projector.
Use left or right keys of the control disc to change the phase of the Reference
Source. Use both (up or down) or (left or right) so that the green vertical lines
perfectly match the right-left edges of the reference image, then press
<ENTER> (this will initiate the learning procedure).
NOTE: If you had to use the left and right arrow keys to adjust the phase, this
means that the phase of the Reference Source was originally not adjusted cor-
rectly. Hence the Reference Source may now fall short of the physical screen.
To avoid this, re-adjust the Horizontal Raster Shift (in the Random Access
Adjustment mode, refer to Owner Manual) so that the Reference source falls on
the physical screen and repeat the Learn Reference selection.
Do not adjust the phase when repeating the Learn Reference procedure.
Pressing<EXIT> will interrupt the Learn Reference procedure if required.
WHA
T IS BEING MEASURED BY EYE-Q
TM
Using the borderlines define above, EYE-Q
TM
knows exactly when the image
starts and stops with respect to time scale. EYE-Q
TM
is now able to project lines
at the edges. Using the border lines left and right, EYE-Q
TM
projects three ver-
tical thick green lines at positions 5, 50 and 95%. Using the border lines top and
bottom, EYE-Q
TM
projects three horizontal thick lines at positions 5, 50 and 95%.
EYE-Q
TM
then calculates the intercepts of the three vertical and three horizontal
lines resulting in nine points. These nine points are the reference points for
other geometry sources and are stored into memory.
NOTE: “DELETE ALL BLOCKS” in the Service menu does not delete the Ref-
erence source parameters.
