中文摘要 | 摘 要 隨著高畫質電視(HDTV)及數位電視(Digital Television)時代的來臨,未來電 視節目將更能呈現細微的光影及材質,隨著電腦科技技術在各個領域逐漸加強其影響 力,過去十年來在傳播領域所產生的變化也十分鉅大,特別是在節目錄製及後製合成 方面,所有的新產品均以輕薄短小且功能強大為開發方向。在傳統的節目錄製過程 中,節目企劃案確定後,緊接著是場景道具的設計及搭建,節目錄製過後,場景及道 具的拆解、運送及儲藏,這些過程其實耗費許多的人力、時間及金錢上的花費。 虛擬攝影棚(Virtual studio)的適時出現,提供了許多節目製作的新方向,它成為 最近幾年來在電視製作上較具突破性發展的數位產品之一,充分結合了最新科技及藝 術,也改變了傳統節目製作及畫面呈現的方式,它已將許多製作節目的限制解除,然 而畫面品質的提昇,是目前虛擬攝影棚首先必須克服的難題,由於受限於電腦即時運 算的能力,往往為了良好的執行效能而犧牲畫面品質,然而畫面品質的提昇方式,除 了等待軟硬體的效能提昇外,非即時算圖方式(Non Real-time Rendering)是一個相當 值得研究的方向。 本研究將以虛擬攝影棚的原理及相關技術為基礎,分析及研究以非即時算圖的方 式,如何提昇製作品質為研究範疇,期望能對於國內的學界及業界有所助益。 |
英文摘要 | Abstract With the coming of HDTV and digital TV, they can present the subtle light and texture in design of the TV programs and this will help the whole TV programs show plasticity. Also, the influence of the computer technology prevails in many fields, such as electronics, publishing, broadcasting, etc. Especially in the broadcasting field, computer technology has been helping improve the recording of traditional TV programs and post-composition from the past ten years until now. In the procedure of the recording of TV programs created by traditional methods, once the project of a TV program is settled, the designing and the building of scenes are the next. Further, the disassembly, movement and storage of these tools do really cost much time, money and human energy. With the help of the computer technology, these difficulties will be easily solved and make it more efficient. The coming of the Virtual Studio recently becomes one of the famous and developmental digital products, which not only offers a new direction for many TV programs to be designed, but also combines the art and the new technology to make it more efficient and to make it easier to create a scene that is hard to make it happen by traditional method. There is an bottleneck that Virtual Studio has to solve is about the improvement of the image quality of the scenes. The reason is the limitation of the operation of computer. In order to get a better efficiency of the computer operation, sometimes the designers should ignore the image quality of the scenes. Thus, except for waiting for the advancement of the software and hardware, using Non Real-Time Rendering provides a new direction of the study in this field. |
