摘要(中) 隨著科技日益月新的發展,人們對於攝影越來越熟悉,隨手記錄回憶,錄下生活的點點滴滴。而照明系統則是在拍攝時不可或缺的輔助工具,但傳統的閃光燈無法在拍攝同時補光,以及照度分佈過於集中容易造成影像過度曝光而影響成像的品質,且在微距拍攝時,補光較為困難,以及系統對焦速度較慢。為了改善上述之問題,本研究提出新穎的照明與成像同軸系統-視覺輔助對焦照明設計。
照明與成像同軸系統,採用照明與成像同步聚焦設計,此系統可以改善過度曝光、照度分佈狹窄和光源不均勻的問題。本論文著重於視覺輔助對焦照明設計,系統架構為相同的六組照明端環狀排列在成像端周圍,且照明端與成像端共用一組可變焦的Image lens system,使兩者的對焦範圍與拍攝距離皆一致。藉由照明端投射出均勻且高銳利度之邊緣照明影像,可透過人眼觀察照明端投射出之均勻光源的邊緣銳利程度,即時判定成像端之聚焦程度。
本研究之光學系統在微距拍攝以及光線不足的環境下有較佳的照明品質,根據不同拍攝距離下,調整系統對焦位置與放大率,人眼皆可即時分辨系統之聚焦程度。
摘要(英) People usually take photographs by using camera for record life in recent years. Fill flash light is necessary when we’re doing a shoot at night for illumination. However, it makes to raise overexposure easy and effect image quality. In addition, the traditional flash can’t simultaneously fill light and shoot. In order to deal with the problem mentioned above and to be sure the illuminated light located only on the same region as the objects of photography, we developed a novel The Illumination and Imaging of Coaxial System- Illumination Design of Visual Assistance Focusing.
The illumination and imaging of coaxial system is the illumination focus that does synchronize with imaging. This system can improve to exposure and illumination distribution and uniformity of illumination. The thesis is focus on illumination design of visual assistance focusing. The system is composed of six group illumination sides which are arranged the imaging side around and share a set of zoom image lens. The illuminated range is found on match the intended imaging region. The human eye can observe an edge of illumination pattern, real-time determination of the degree of focal imaging side through the illumination system is projected the uniformity distribution source and high sharpness edge pattern.
This thesis show the illumination and imaging of coaxial system is much better fill illumination effects for the macro photography and lack of light environment. The human eye can discern focus level to the different zoom ratio with respect to objects located at different distance.
