What can Edge Blending and Warping Solutions offer? The good folk at TripleWideMedia have the following list of downloadable edge blending projection content:
In order to blend it together, you need to reduce the brightness in addition to matching the image. If you have two images side by side and the middle 20% is doubled, obviously that portion is going to be brighter than the rest of your image. The second part of the process involves feathering the images to eliminate the “hot spot” that is guaranteed to occur. This overlapping gives you a larger area to match up which eliminates the hard edge you’d see if you simply placed the two images side by side. Essentially, you send the same portion of your image across two projectors.
The first involves overlapping two images. So, how does edge blending really work? There’s basically two processes. Essentially, this is what edge blending will accomplish.
Much like when you paint a wall, you always overlap your strokes to get as even a coverage as possible. When you place two projectors side by side, the human eye will notice the edge, the mismatched colors, and the split or overlap of the images. Simply put, when you have two projectors lined up next to each other creating one solid image, you will never be able to create a seamless edge without edge blending projectors. In both cases, a number of projectors are needed which are firstly overlapped and then visually joined together using an edge blending technique. Typically, this is done to increase the size of a projected image to make a very wide image, or by combining a number of lower resolution devices together to increase the total resolution of a display. Edge blending is a technique used to describe the process of visually combining several projected images to make a single seamless image.
