Abstract
A curved image conversion method is provided which converts a curved image formed by a fish-eye lens into a plane image at high speed. The conversion from the curved image into the plane image involves calculating through a geometry calculation projection points on a plane that are projected from sampling points on the curved image formed by the fish-eye lens.

A method for converting a curved image produced by an imaging means into a plane image, the method comprising the step of:
- calculating by a geometry calculation projection points on a plane that are projected from sampling points on the curved image formed by the imaging means to convert the curved image into the plane image without using an orthogonal system conversion algorithm.
A method for converting a curved image produced by an imaging means into a plane image, the method comprising the step of:
- calculating sampling points on the curved image based on projection characteristics of the imaging means to convert the curved image into the plane image without using an orthogonal system conversion algorithm.
A recording medium storing a curved image conversion method, which method converts a curved image produced by an imaging means into a plane image, the method comprising the step of:
