Selecting Projectors May Require Los Angeles Edge Blending Expertsįor edge blending, you need to use two or more projectors. There are four AV components you need for this type of video wall setup: The individual components and specific edge blending technology used will depend on your unique needs and requirements. Only custom AV projection systems with precise edge blending solutions will appear seamless. It takes commercial audio-visual integration specialists to achieve the best results. Four Audio-Visual System Elements for an Edge Blended Projection Video WallĪs you can imagine, in Los Angeles, edge blending requires complex audio-visual know-how. In effect, this stitches those two images together, reducing brightness in addition to matching the image. To edge blend, feathering tapers the left edge of the right projector down to black and the opposite edge for the left projector. Feathering reduces the brightness in the overlapping area-hot spot. So, to correct it, we use feathering, an image blending technique. In the two-projector example we mentioned above, the overlapping area between the two images is noticeably brighter than the rest of your image. The second part of the edge blending process involves blending the images or feathering the images.

Because the shared space where the two images overlap comes from two projectors, it will be much brighter than the rest of the image. Data-doubling is a requirement for edge blending. The projectors share from 15 to 25% of their individual horizontal resolution. With a two-projector setup, the right edge of the left projector is sharing the same information as the left edge of the right projector. The overlapping images help create a seamless image.

To simplify, we will talk about edge blending here with two projectors. We overlap images from two or more projectors onto a display surface. Data-Doubling Overlapping Imagesĭata doubling is the process of overlapping more than one image onto one surface. Second, we will detail the feathering part of edge blending. First, we will explain data-doubling, an image overlapping process. There are two main parts to successful edge blending. It allows us to combine images from two or more projectors into one seamless image that is larger in size and resolution. In Los Angeles, edge blending is what makes this seamless imaging possible.

To them, what they see is seamless and comes from one projector. Ideally, your viewers will remain unaware that the projection they see is from multiple projectors. Edge blending is something your audience will never notice. When images from two projectors are side by side, the human eye focuses on the mismatched area between the images. Why do we need edge blending? It is simple. To create these life-sized digital wallpaper video walls, multiple projector systems incorporate edge blending to unify into a digital canvas. These video walls also help to create immersive experiences for museums. Think about the screens we see behind news anchors and sportscasters. These are the massive video displays behind performers in houses of worship, teachers in education, and presenters in corporations. But we want you to understand that this is the secret behind the seamless-looking wall-to-wall videos seen all over Los Angeles. Here we will dive deeper into edge blending techniques shortly. Los Angeles edge blending is the use of multiple projectors to create an image on a singular screen or surface. In Los Angeles, Edge Blending Seamlessly Shows Your Brand on a Large Scale
