The 3D display using super high-density multi-view images is expected as a display that enables to reproduce natural stereoscopic view. In this super multi-view display system, viewpoints are sampled at an interval narrower than the diameter of a pupil of an eye. With the parallax produced by the single eye, this system has a possibility to pull out the accommodation of an eye to an object image. This research aims at a real-time view interpolation system for the super multi-view 3D display. We have developed an evaluation system. Multi-view images of the object are captured by multi-view camera by convergence capturing in order to prevent resolution degradation. The main processing of the data processing is view interpolation and rectification. View interpolation is implemented on a high- speed image processing board using DSP chips or SIMD parallel processor chips. As for the view interpolation algorithm, we adopted an adaptive filtering technique on EPI. By this technique, multi-view images are interpolated adaptively by the most suitable filters on the EPIs. Rectification is a preprocessing and changes the multi-view images of the multi-view camera in convergence capturing into the ones in parallel capturing. By using rectified multi-view images, it is enabled to attain improvement in the processing speed that the view interpolation processing should be performed in only horizontal line.
