| dc.description.abstract | 色盲或色弱並非是罕見的疾病，平均100人中就有5個人可能因先天遺傳或是後天的傷害而患有此類的疾病。這種疾病雖不嚴重但卻為病人帶來了許多生活上的不方便，即使是『看電視』這類普通的活動都不能從中獲得跟正常人一樣的樂趣；因此如何改善色盲患者的生活品質是個很值得探討的問題。隨著數位時代來臨，數位電視不僅為人們帶來了高品質的節目，各種數位資訊更能經由數位傳輸帶到每個家庭中，相較於傳統的類比電視，數位電視是個整合科技，除了提供互動式的節目外，更提供豐富的多媒體資訊，使得數位電視在未來將成為每個家庭的多媒體平台。因此數位電視平台提供了適當的機會讓我們可以為色盲使用者調整節目影像色彩，使得色盲使用者也可以提升生活品質及樂趣。在這篇論文裡，我們在數位電視平台上設計了一個色盲濾波器，提出了一個演算法，使得數位影像在播放之前能先調整過顏色，使色盲使用者能夠清楚辨認顏色的不同，這個演算法不但增加了色彩對比度，更會針對某些色盲使用者無法辨認的顏色做調整。另外還提出了一個確保在同一塊區域內合理改變顏色的機制，使得在同一塊區域內不會有某些顏色改變而某些顏色不變的情況發生。我們不但將此演算法以軟體驗證，更實現在硬體上以驗證它的執行速度及效能。 | zh_TW |
| dc.description.abstract | Colorblind is not a rare disorder since 5% of people in the world have some sort of color deficiency. To improve convenience of life for colorblind people is an important issue. Digital TV system is an emerging technology that provides multimedia information and interactive services which are not possible in traditional analogue TV systems. Moreover, it offers opportunities to further process video or multimedia data for various purposes, for example, enhancing discrimination for colorblind users. In this thesis, we propose the DTV Colorblind Filter to analyze color component and adjust color by increasing contrast of video or re-coloring video on a DTV platform. We also propose a mechanism to refine color in the same region to make sure that re-coloring in the same region will be more reasonable. The filter can be integrated into digital TV set or a separate digital TV receiver to adjust color of each image before displaying. We implement partial operations of our algorithm on an FPGA to accelerate the process speed and to verify the efficiency of DTV Colorblind Filter. In light of the experimental result, the filter is being implemented in full scale. | en |
