Abstract

A method for correcting and presenting a barrel distorted image is disclosed. In the method an output image is created having a user-defined aspect ratio (AR), and the method comprises acquiring a continuous flow of barrel distorted images in a video camera and processing the image in an image processing unit. The processed image is added as an output image to an image stream, and the actual processing includes applying a barrel distortion correction so as to form a corrected image having a smallest width (w') and a smallest height (h′), and generating the output image by cropping the corrected image to a height exceeding or equaling the smallest height (h′) and having the user-defined aspect ratio (AR).
