 # Correcting for the lens distortion on Neon's scene camera
-A circumstance that often arises in wearable eye tracking setups is the presence of distortions on the scene camera. The type of lenses used, with their wide-angle characteristics, allow for a broad field of view, enabling the capture of more information within a single frame. However, this advantage comes at the cost of introducing distortions to the image. <!-- rectilinear distortions -->

 While we account for them in Pupil Cloud, and we even give you the possibility to download the undistorted video using the [Gaze Overlay enrichment](/enrichments/gaze-overlay), this is not the case when using the [Realtime API](/neon/real-time-api) or raw data, where you may want to correct it by yourself.

 ## How to correct for the lens distortions?
 In this tutorial, we will cover how to read the provided intrinsic and extrinsic camera parameters and correct for the lens distortions in Neon's scene camera. We will also show you how to undistort the gaze data, so that you can map the gaze position onto the undistorted scene camera video.
 
-We will be using Python and OpenCV to perform the undistortion but the same principles apply to other programming languages and libraries.
