R5906151 /02 XDL90Example of the use of blendingWhen projecting an image with 2 or more projectors, there is always an small overlap that should be correctedby using the blending function.In order to obtain a satisfying result for the Blend function, the overlap / mask zone arerecommended to be at least 10% of the picture width.The basic principle is that the overlap setup in the source shall correspond with the mask width setup for theprojector. That means that if the overlap zone for the source is set to 500 pixels, the width of the mask zone forthe projector also must be set to 500 pixels.First step is to align the image from the projectors as accurate as possible in a mechanical way, meaningwithout any optical corrections. At the same time, establish an overlap in the pictures between the twoscreens.Then adjust the remaining irregularities by using the shift and warp features in the projectors to obtain the lastfine tuning of the alignment.Enable blending and activate Show lines.First set the mask width for the right edge of the first projector. Enter a width value equal to the overlap area(width1).Repeat for the left edge of the second projector.Adjust the offset to cut the image on each side (masking).Image 8-45: Set up for projector 1Image 8-46: Set up for projector 2GUI – Installation
