Abstract
This paper proposes an interpolation algorithm and LSI architecture for a camera with a fish-eye lens. Since the fish-eye lens has around 180 degree field of view and a deep depth of field, it's very promising for a surveillance camera, a video conference system, and so on. Combination of a cubic spline interpolation and a direct interpolation from a RAW image enable to obtain high quality image. A three-stage linear interpolation scheme and a dedicate operators boost up processing performance. Evaluation results base on a subjective test show that our proposed algorithm can generate high-quality interpolation image. Furthermore, a dedicated image processing core with 290k gates can process HDTV (1920x1080, 60 fps) image by using 0.18 µm CMOS technology.
