CP-XN(CI-N) / CP-XN(CI-N) / CP-XN(CI-N) / CP-XN(C-N) / ED-XN(C-N) Adjustment procedure (When a color differential meter is used). First adjust the [MID-] tone [G:].. Select adjustment point [No.][G:]. When the background is not [G] monochrome, press the [ENTER] key on the remote control to switch to solid [G] monochrome.. Measure the illumination at adjustment points No., No., No. and No.. The values should be: No. = Y [lx] No. = Y [lx] No. = Y [lx] No. = Y [lx]. No. and No. adjustment points have the average of Y and Y. Y = ( Y + Y ) / ± [%] Y = ( Y + Y ) / ± [%]. No. and No. adjustment points have the average of Y and Y. Y = ( Y + Y ) / ± [%] Y = ( Y + Y ) / ± [%]. Then adjust the [MID-] tone [R] and [B]. When the background is [G] monochrome, press the [ENTER] key on the remote control to switch to solid white.. Measure the color coordinates of adjustment point [No.] and make a note of them. Assume that they are x = x, y = y. Note: When the CL- color and color difference meter is used, the [ ](delta) mode is convenient. When adjustment point [No.] color coordinate has been selected, set the slide switch on the side to [ ](delta) while holding down the [F] button on the front panel. The measurement shown after this displays the deviation from measurement point.. Measure the color coordinates of measurement point [No.] and adjust [No.][R:] and [B:] so that the coordinates are as follows. x = x ±., y = y ±. 9. Similarly, measure adjustment points [No.] to [No.] and adjust their color coordinates starting in order from the small number points. This completes adjustments required for [MID-]. Note: Since excessive correction may lead to a correction data overview during internal calculations, use the following values for reference. [No.] to [No.] ± or less [No.] to [No.9] ± or less [No.] to [No.] ± or less [No.] to [No.] ± or less. Then adjust the [MIN] tone [G] so that the adjustment values are two times as much as MID-] tone [G] values. This completes [G] color adjustments.. Then adjust [MIN] tone [R] and [B]. Select [No.] [B:] and press the [ENTER] key on the Remote control transmitter to change to solid white.. Measure the color coordinates of adjustment point [No.] and make a note of them. Assume that they are x = x, y = y.. Now measure the color coordinates of measurement point [No.] and adjust [No.][R:] and [B:] so that the coordinates are as follows. x = x ±., y = y ±. (Target) x = x ±., y = y ±.. Similarly, measure adjustment points [No.] to [No.] and adjust their color coordinates starting in order from the small number points. This completes [MIN] tone adjustments.. Now make similar adjustments for [MID-] tone. (Adjust [MID-] tone [G] so that the adjustment data set half as many as [MID-] tone [G].). Now make similar adjustments for [MID-], [MID-], [MAX] tones. (It is not necessary to adjust the [G] data in these tones.). After completing the step, set the value of the [MID-] tone [R]: [No.] to the mean of the values of the [R]: [No.] in the [MID-] and [MID-] tones.. Set all the values for the [No.] to [No.] of the [MID-] tone [R] and [B] in the same way as the step. 9. Finally, set the data of the [MID-] tone [R] and [B] using the values of the [MID-] and [MAX] tones in the same way as the [MID-] tone [R] and [B] adjustments in the step and.
CP-XN(CI-N) / CP-XN(CI-N) / CP-XN(CI-N) / CP-XN(C-N) / ED-XN(C-N) Adjustment procedure (visual inspection). First adjust [MIN] tone [G:].. Select [No.] [G:]. If the background is [G] monochrome, press the [ENTER] key on the remote control to switch to solid white.. View measurement point [No.] and [No.]. Lower the [G] color intensity only of the color point whose [G] color is more intense than measurement point [No.].. View measurement point [No.] and [No.]. Lower the [G] color intensity only of the color point whose [G] color is more intense than measurement point [No.], and raise the intensity of the point whose color intensity is lower than measurement point [No.].. Now adjust the [MIN] tone for colors [R] and [B].. View measurement points [No.], [No.], [No.] and [No.]. Adjust the [R] and [B] of each measurement point so that they have the same color as measurement point [No.]. Adjustment technique: First, adjust [B:] of the point whose color is to be adjusted so that it approximates that of [No.]. 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.. Next, view measurement points [No.], [No.], [No.], [No.] and make similar adjustments.. Then adjust measurement points [No.], [No.], [No.], [No.9], [No.], [No.], [No.] and [No.]. This completes the [MIN] tone adjustments. 9. Make similar adjustments for other tones, except the [MID-] and [MID-] tones, as described in steps to above.
