Adjustment procedure 2
(visual inspection)
1. First adjust [MIN] tone [G:].
2. Select [No.2] [G:].
If the background is [G] monochrome, press the
[ENTER] key on the Remote control transmitter
to change to solid white.
3. View measurement point [No.2] and [No.3].
Lower the [G] color intensity only of the color
point whose [G] color is more intense than
measurement point [No.1].
4. View measurement point [No.10] and [No.11].
Lower the [G] color intensity only of the color
point whose [G] color is more intense than
measurement point [No.1], and raise the
intensity of the point whose color intensity is
lower than measurement point [No.1].
5. Now adjust the [MIN] tone for colors [R] and [B].
6. View measurement points [No.2], [No.3],
[No.10] and [No.11]. Adjust the [R] and [B] of
each measurement point so that they have the
same color as measurement point [No.1].
Adjustment technique:
First, adjust [B:] of the point whose color is to
be adjusted so that it approximates that of
[No.1]. If [R:] is low at this time, the image will
have cyan cast, in which case [R:] is increased.
On the other hand, if [R:] is excessive, the
image will have a magenta cast, in which case
[R:] is decreased.
Overall, a cyan cast makes it easy to see color
shading.
7. Next, view measurement points [No.4], [No.5],
[No.12], [No.13] and make similar adjustments.
8. Then adjust measurement points [No.6], [No.7],
[No.8], [No.9], [No.14], [No.15], [No.16] and
[No.17].
This completes the [MIN] tone adjustments.
9. M a k e s i m i l a r a n o t h e r t h r e e t o n e s a s
described in steps 1 to 8 above.
