What Is a Fisheye Camera?
A fisheye camera is a camera that uses an extremely wide-angle lens to capture a viewing range of about 180 degrees. This type of camera is called a “fish eye” because it approximates the vision of a fish’s convex eye. The lens produces curvilinear images of a large area, while distorting the perspective and angles of objects in the image. There are two types of fisheye cameras, and they produce different angles of view, different types of distortion, and different photo shapes. Full-frame lenses capture an image that is usually 180 degrees from corner to corner, while the vertical and horizontal angles are smaller. These images fill the rectangular film frame. Circular lenses generally capture a 180 degree view of the horizontal, vertical, and diagonal angles. Images captured by circular lenses are round or oval inside the film frame and the frame around the image is black.
