  • 近年來由於大量人力資源投入立體顯示技術的研究,使得此領域的發展相當快速,應用於立體顯示器有許多代表性的技術,主要可分為兩大類:眼鏡式與裸眼式立體顯示器,其中,前者需要配戴特殊的光學眼鏡才能使觀看者看到立體影像,而後者則無需配戴眼鏡。柱狀透鏡型裸眼立體顯示器就是典型的裸眼式立體顯技術之應用。
    由於柱狀透鏡型裸眼立體顯示器是以平面顯示器為主結構並配合柱狀透鏡以產生立體影像的效果,因此,平面顯示器的內部結構與性能表現便會影響立體影像的品質。本論文以實驗方法研究不同畫素排列的顯示器對於柱狀透鏡型立體顯示的影像之影響,實驗結果顯示垂直排列時立體影像有色彩分離的問題,水平排列與馬賽克排列的影像表現相對較好。最後,我們嘗試用常見的影像評估方法對實驗結果所表現之立體影像進行客觀量化的評估。

    Recently, numerous manpower have been invested in research of 3D display technologies in order to speed up its realization in our daily life. Although many typical technologies have been demonstrated, they are always belonged to two major categories. The one is stereoscopy that viewers need specific glasses to see 3D images. The other is autostereoscopy that viewers see 3D images with their naked eyes. Autostereoscopy based on periodic lenticular lenses is a typical 3D display technology.
    In usual, autostereoscopy generated by flat panel displays via periodic lenticular lenses possess 3D images usually sensitively affected by detailed display configurations such as color pixel arrangements. In this thesis, we study 3D imaging performance with respect to color pixel arrangements via an experimental setup similar to an autostereoscopic display with periodic lenticular lens. From experimental results, we conclude that color separation is very obvious in 3D images when using vertical color pixel arrangements, which seems to be not observed when using horizontal or mosaic color pixel arrangements. Finally, we use an objective and quantitative evaluation to prove the consistency between experiments and quantitative evaluation.
