10-3 多焦点レンズ型 3D 表示方式のキーデバイスである偏光切替器のコントラスト改善(第10部門 立体映像技術)

抄録

We propose contrast improving method in 3-D image using multi-focus lens. The image quality of this 3-D display was degraded by ghost image which were caused by low contrast ratio of polarization-switching device. This degradation can be successfully improved by phase control of input and output lights using half-wave plate.
