In this paper, we propose a modified interpolation method considering a barrel distortion of fisheye lens. The interpolation method using coordinates come close to corrected image not being distorted image unlike existing techniques is proposed. In addition, when executing of suggested method, the structure of look-up tables (LUT) is proposed for performance improvement. Experimental results show that objective image quality (PSNR) are improved, and performance is improved through the structure based on LUT.
