Method and apparatus for correction of an image from a fisheye lens in a camera |
| 摘要 |
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. |

1. A method of operating a video system, comprising the steps of:
receiving a first image captured by use of a fisheye lens; dividing the image into a plurality of horizontal image lines, each image line having a middle portion and two lateral portions, a size of the middle portion relative to the lateral portions increasing with each horizontal image line from a top of the image to a bottom of the image; discarding the lateral portions of the image lines; representing each of the middle portions by a substantially equal number of samples; and forming a second image including the samples. |
