Abstract:
A method of operating a video system includes receiving an image captured by use of a fisheye lens. The image is divided into a plurality of horizontal image lines. A respective fraction of each of the horizontal image lines is sampled with a different respective sampling frequency. Each sampling frequency is inversely related to a size of the sampled fraction. The size of the sampled fraction increases with each horizontal image line in a progression from a top of the image to a bottom of the image.
