Advanced Projection ■ Black Level Adjustment In overlapping projection, dark colors are projected with less intensity than other colors in the overlapping area. You can make this overlapping area less distracting by adjusting the black level of non-overlapping image areas. Left image Right image Area where dark colors look lighter Position of end marker (hidden) D-area Blending area Here, the non-overlapping image area (from the end marker toward the center of the image) is called area "D." Normally, three areas are identified in the context of end markers: A, B, and C. In the following instructions, only area D is adjusted, and the widths of A, B, and C are left at the default value of 0. To prepare for adjustment, set [No signal screen] to [Black], start projection with no input signal, and turn off the room lights, so that you can check dark image areas. (P117) 1 In the [Install settings] menu, select [Professional settings] > [Edge blending] > [Adjust] > [Black level adjustment] > [Adjust]. 2 Select [Adjustment type] > [Black level]. 3 After selecting [D-area base], as you watch the image, adjust the values so that the brightness and colors of the blending area and area D match. Adjust [D-area base] to lighten the black level, and adjust [Red], [Green], and [Blue] to obtain an optimal black level color tone, as needed. 4 Repeat this adjustment on all projectors. 164
