Panasonic Projectors
Edge blending notes. – (example: PT-D6K Series).

The following describes the setup of a simple edge-blend application using two single-
chip projectors mounted side-by-side with the same signal source applied to each. (The
concept is that two lower resolution projectors (e.g. 1280 x 800) are combined to enable
the display of a higher resolution source (2432 x 800) without scaling).

1. Set the projectors side-by-side, aligning them so that they are level and as squar

8. Calculate the amount of overlap that will be used. (10 ~ 15% or so of the image width is recommended - this works out to be 4 ~ 6 boxes of the grid pattern, depending on the horizontal pixel count of the projectors. Each grid box is 32 pixels by 32 pixels, so 128 pixels equals 4 boxes, 160 pixels equals 5 boxes, 192 pixels equals 6 boxes, etc. The number of pixels chosen for optical overlap will also be entered in the “Width” setting on the Edge Blend page). 9. Adjust the zoom, and V

17. Select Bright Adjust / Bright Inside. Leave it in Interlocked mode. Raise the “White” value up to about 50. You'll notice the black level increasing, starting at the red marker that lies just within the overlap area 18. MENU back up to the Bright Adjust menu and adjust the LEFT value - you'll see what looks like a wipe pattern moving to the right, starting from the red marker. Move the position of this “wipe-edge” to the right until it aligns with the edge of the overlap area, whic

27. Once the images are overlapped properly, save the projector’s current setup state in a sub memory with the FUNC1 key. (Rename the sub memory entry if this option is available) Further steps 28. With actual picture material you might tweak the left and right edge-blending widths, as well as brightness and contrast a bit to make up for the raised black level. 29. Note that the blend quality is image dependant – appropriate material should be chosen to show the blend to best effect.
