✔

Note:

• The overlapping area might become uneven depending on the images. In such a case, it is recommended to

decrease the contrast of the images in the Image Adjust Menu.

If the colors of the left and right images do not match, then follow the next step.

Select Color matching in the setting menu and display the Color matching dialog box.

Then, set Color matching to On and adjust the color settings (Red/Green/Blue).

(Refer to pages 57, 58 for operation procedure.)

Color matching

✔

Note:

• When you change the values of Target, make sure that each

Target value should be within the range of Measured value.

(e.g., In the case of the Fig.1, the X value of Target-Red

should be within 0.674 which is the X value of Measured-

Red.)

Set to On.

Set Test pattern to On to display a 50 % white image. The overlap area will be brighter than the non-overlapping area.

Adjust the Black level in the Edge blending dialog box to increase the brightness of the non-overlapping area so that

the unevenness is reduced.

Select Advanced color matching if you need further adjustment.

In the Advanced color matching dialog box, set Advanced color matching to On and adjust the values of Target (Red/Green/

Blue/ Cyan/ Magenta/ Yellow/ White).

If color unevenness is still detected between the left image

and right image, measure chromaticity coordinates and

luminance of Red, Green, and Blue by using a colorimeter,

and then input the measured values by following the steps

below.

1. Ensure that the Advanced color matching function is set

to “On”.

2. Highlight “Test pattern” appearing at the lower part of the

window and press the SELECT button to display the Test

pattern window.

3. Select Red, Green, or Blue and press the SELECT button

to display the test pattern.

4. Measure chromaticity coordinates (X and Y) and

luminance (Lx) by using a colorimeter.

5. Highlight “Exit” in the Test pattern window and press the

SELECT button to return to the Advanced color matching

window.

6. Highlight the color of the coordinates and luminance that

you measured at the step 4, in the Measured section, and

press the SELECT button.

7. Input the measured chromaticity coordinates and

luminance values in the x and y fields.

8. The values to be input in the L fields can be calculated

according to the following formula:

L = Measured luminance of the color ÷ total measured

luminance of all colors (Red, Green, and Blue).

9. Readjust the Target values.

10. Highlight “Store” appearing at the lower part of the

Advanced color matching window and press the SELECT

button to store the values.
