隨著科技的進步,3D立體電影帶來新一波的視覺革命,讓3D相關的產業蓬勃發展,立體顯示器由電影院走進一般家庭,由戴眼鏡式發展到裸眼式的立體顯示器,不過由於觀看3D立體影像後會產生不舒適感,造成3D相關產品銷售不如預期,因此,裸眼式立體顯示器的視覺舒適度是個值得探討的重要課題。
電影院與一般家庭的環境光照度有很大的不同,立體顯示器的尺寸的差異非常大。智慧型行動裝置逐漸充斥我們的生活中,在平板電腦上縮放2D平面影像非常方便,但3D立體影像的縮放會造成影像內容的視差改變,這些差異對於視覺舒適度會不會有影響?本研究的目的為探討在不同的觀看條件下視覺舒適度的變化,利用視覺舒適範圍會隨著不同觀看條件而改變,去探討因子對於視覺舒適度影響。
基於上述的研究目的,提出四種不同的影響因子,分別為環境光照度、影像的縮放比例、影像的內容、影像中主物體與次物體的間距變化對於視覺舒適度的影響。實驗結果顯示:(1)在環境光照度越亮時視覺舒適度越低,觀測者可以承受的視差範圍變小,較不舒適。(2)影像中物體的縮放比例對於視覺舒適度沒有顯著性的影響。(3)影像的內容對於視覺舒適度有顯著性的影響。(4)影像中的主物體與次物體的間距變化對於視覺舒適度沒有顯著性的影響。
Stereoscopic display is becoming a popular product in the future. Unfortunately, its development is subjected to certain factors such as lack of 3D programs, uncomfortable watch feeling and inconvenient wearing glasses. User friendly and visual comfort will be the main goals for improving 3D images. Based on these facts, the autostereoscopic technologies have been developed and integrated widely into 3D monitor application at present.
Most of 3D technologies were only applied in the cinema in the past. But with the advanced 3D technologies, stereoscopic display has been walking into general families. When the viewing environment changed, the ambient illuminance becomes as an important factor in watching 3D display. In addition, image scaling is one of the main functions on 2D image operation. Users may zoom in or zoom out the images on the screen conveniently when using mobile phone. However, this kind of control is not considered in the 3D image yet. So, the scaling of 3D image is also an important issue in the stereoscopic display field.
The aim of this study investigated the ranges of parallax among ambient illuminance (AI), image scaling (IS), different image contents (IC) and the relationship between relative moving position of the minor object (DMM) and visual comfort threshold. In this study, we explore the visual comfort through the visual comfort zone. The evaluation of the questionnaire gave us more information about the personal visual comfort zone. The results showed that the AI and IC will affect the 3D visual comfort, which provide the factors needed to be considered on the production of 3D programs in the future.
