S-Cur ve Value (continued)
When images overlap, the area of overlap receives light from all overlap\
ping sources. Without S-Curve, the overlapping edges would be
brighter than the rest of the image, as shown in Fig. 1.
If two reciprocal s-curves are used to control the amount of light from \
each source in the overlapping region, the total amount of light in the \
region would remain constant, as shown in Fig. 2.

page 54 Operating Guide USING THE PROJECTOR Edge Blend menu Over view When several projectors are used to create a large tiled image, the edges need to be blended to avoid the overlaps appearing brighter than the rest of the image. As it is not possible for any projector to produce an absolute black, any ‘black’ areas in the overlapped edges may appear slightly less dark than those in the rest of the image. Black Level Uplift can be used to counteract this effect, by raising the black level of the rest of the image. The amount of uplift required will be either x2 or x4, depending on how many images are overlapped, as shown in the examples on this page. Image brightness changes from one point to another, within the same blended region. If the same level of black level uplift is applied throughout the blended region, the overlapping edges may still be visible on the screen. Therefore, brightness in these areas is decreased gradually, using an s-curve factor. S-Cur ve Value is used to control the steepness of the decrease.

None of the other items in this menu are available until either the Array Width or the Array Height setting is greater than 1.

page 55 Operating Guide USING THE PROJECTOR Array Width and Height • Set this to the total number of projectors in the array. None of the other options are available until one of these two settings is greater than 1. The maximum number of projectors is 4 x 4. Array H Position and V Position • These two parameters need to be set correctly for each projector in the \ array, so that it can determine which edges are to be blended. Sometimes only one edge overlaps, sometimes two, three or four. Example The illustration shows an array of sixteen projectors. Array Width and Array Height of all projectors have been set up as follows: • Array Width = 4 • Array Height = 4 Array H Position and Array V Position of each projector have been set up to reflect its vertical and horizontal position in the array. The settings for the third projector in the second row 1 are: • Array H Position = 2 • Array V Position = 1 Notes Main MenuEdge Blend This menu is available only when Setup > System > Configuration is set to Edge Blend. None of the other items in this menu are available until either the Array Width or the Array Height setting is greater than 1. The position numbering starts from zero, so the top left projector is at position H 0, V 0. Which settings are available in these menus depends on: ● the number of projectors in the array ● the position of the projector in the array An image like the one shown here can be produced by an array of 16 projectors only if Segmentation is set to ON, or if an external tool is used to split the image into segments. See Segmentation further in this section.

page 58 Operating Guide USING THE PROJECTOR Blending This setting enables s-curve blending, or displays an align pattern to help define overlaps between segments. Set Blending to: • Off Edge Blend is not used. • On S-curves are enabled in the overlapping regions. • Align Pattern The align pattern makes the overlaps more visible and helps adjust the physical position of the projectors in the array. The size of the align pattern is controlled by the Blend Width group of settings. Notes Main MenuEdge Blend This menu is available only when Setup > System > Configuration is set to Edge Blend.

Counteract this effect by raising black levels in the rest of the image. The amount of uplift required will be either x2 or x4, depending on how many images are overlapped. The following example shows a segment with overlapping edges on all sides. 5 Unblended Region This region is not overlapped. Black level should be raised by the maximum overlap occurring within the segment, therefore Black Level Uplift should be x4. 6 Upper Middle This section of the image is overlapped by two projectors, therefore the correct amount of Black Level Uplift should be x2. 7 Upper Right This part of the image is overlapped by four projectors, therefore Black Level Uplift should not be applied. 3 12 4 756 Notes To apply the settings in these menus, use the Apply command at the bottom of each page.

page 62 Operating Guide USING THE PROJECTOR Reduce Black Level Uplift Width Use this to correct for stray light from the pond of mirrors, the DMD’s inactive outermost mirrors. In the example below, the blended image comes from two projectors, 1 and 2. Both images have black level uplift applied in their unblended regions; as a result,\ artifacts 3 and 4 have emerged at the edges where the black level uplift region of one projecto\ r overlaps the pond of mirrors of the other. To remove the artifacts, you need to slightly reduce the size of the blac\ k level uplift region of each projector so it does not overlap the pond of mirrors of the other projec\ tor. 12 34 Notes Main MenuEdge Blend Reduce Black Level Uplift Width To apply the settings in this menu, use the Apply Uplift command at the bottom of the page.
