Adjustment procedure 2
(visual inspection)

1.  First adjust [MIN] tone [G:].
2.  Select [No.2] [G:].
  If the background is [G] monochrome, press the

[MENU SELECT] 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. Make similar another three tones as described

in steps 1 to 8 above.
