To reduce distracting colors and colors that are out of alignment in areas where the images
overlap, perform [Color blending adjustment] targeting the main tone in the envisaged projected
image.
• Results of adjusting the black level of area B are applied to all sides.
• Blending can be fine-tuned by adjusting [Adjustment type] > [Black level] > [Red],
[Green], and [Blue].
If you perform adjustments using [Color blending adjustment] or other menus, that may
not eliminate the distracting colors and differences in brightness in areas where the
images overlap.
