Lorex Technology’s wide-angle lens gives you an ultra-wide view of your property, while overcoming an inherent flaw of dewarping: cropped images. Instead of setting a high field of view angle, you can set a lower field of view to reduce the fisheye effect. However, there is one solution to resolve the distortion issue. Dewarping is not embedded into Lorex’s surveillance systems just yet. How can I configure distortion from the Lorex Home application?Ĭurrently, the Field of View (FoV) of a camera is neither configurable through the Lorex Home app nor is it controlled by the recorder. Fisheye distortion repair is possible through dewarping mechanism which will tend to shift the image insignificantly.

The Iwerks system, like the IMAX system, is designed to create massive images with extremely detailed, life-like, resolution. When you "correct" the image, you are losing the benefits of having a wide frame of view lens/camera. The lens would have originally been used to project large format film such as 15 perf/70mm that uses an image area 10x larger than the standard 35mm format. This is the trade-off between having a wide frame view lens and having a fairly straight image. The modified image results in a smaller field of view as part of the original image is cropped. Hence the corrected image is just cropped to remove the fisheye effect. The modified image is pulled from the original camera image. The processors cannot do extreme image correction because it only crops the image marginally. Dewarping technology results in shifting of pixels. However, most processors cannot undertake the dewarping feature. How can a straight image be produced?Ī dewarping function is used to automatically correct the curved fisheye image and convert it into a normal image. Instead of showing a straight cut image, it shows a curved image. The effect produces an image that appears distorted. Fisheye effect occurs at a wider viewing angle. If your camera is mounted at a high distance and is focusing on a short point, then it results in Fisheye Effect. This is one of the functions of using a wide lens. A wide frame view (WFV) lens provides an extensive scope, but there will be some barrel distortion as the edges of the lens are symmetrical. If the camera is installed to show a wide-ranging image, it results in an increase in barrel distortion or "Fisheye Effect". Barrel distortion results in image magnification as you move further away from the line of vision. The term "distortion" refers to alteration of an original image. If your camera is showing an image with circular corners, it is because of barrel distortion. What is causing the camera image distortion? This article explains why the camera image is curved or looks like it has a slight fisheye effect.
