- Soft Edge Blending Adjustments
The principle of Soft Edge Blending lies in projecting an image on a wide screen thanks to two or more video
projectors displaying the same content. Overlapping or covering areas are created on the screen where two
adjacent projectors meet. Basically, each overlap zone receives the light of two video projectors and receives
the content projected twice.
The art of Soft Edge Blending is to harmonize, or blend the overlapping area with the rest of the image.
You can use different test patterns provided by your Mixer/Seamless Switcher to make all the necessary
adjustments outside and inside the overlapping area.
To deal with Black level, the solution consists of raising the luminance in the left and right areas of the projection,
outside the overlapping zone, to match the luminance of the overlapping area.
