摘要

本文著重在於為駕駛者提供警訊，並減少駕駛倒車時對外界的撞擊，所開發的汽車影像系統(Vehicle Rear-view)，並且針對各樣的影像品質與測試的方式加以研究探討，如視場角(Field of View FOV)、解析度(Resolution)，並且針對影像感測器，一般只能在該元件的說明書上所得知的光譜響應數值或圖形，利用簡易的方式，並且在有限的設備中，量測到該CMOS影像感測器對各波長光源的響應靈敏度，經實驗發現，利用標準光源箱，透過分光儀將單一波長光源分出，並均勻的投射在該設計的攝影機上，而後測量該攝影機的輸出電壓，進而得到電壓與光波長的響應圖，發現該圖形與該元件的說明書上的圖形相似，雖無法將電子訊號與光子轉換效率作轉換，但由多次的測試結果，比較各種不同型號的感測器，各自可得到不同的響應圖形，將其XY色度值，標繪於CIE1931的色度圖形上，並於攝影機上，所表現出來的品質與效果作一比較

並列摘要

This article emphatically in for the driver provides the danger Signal，Reduced driving back-draft foreign hit，Develops Vehicle Rear-view，and performs in view of all kinds image quality and the test way to study the discussion，Like Field of view(FOV)、Resolution、Gamma Curve, and in view of the CMOS image sensor element, Generally only can the spectral response value or the graph which knew in this part instruction booklet，Seeks a way, and in the limited equipment, Survey to this CMOS image sensor element to various monochromatic light response sensitivity, The research discovered，Using the standard light box, penetrates the spectrometer to branch out the monochromatic spectrum light, and even projection in this module，After survey this module output , then obtains the voltage & the light wave length response chart，we can find this graph is similar with in this part instruction booklet graph, although is unable to know the transfer electronic signal and the light transfer efficiency，But by many times test result, each one may obtain the different response graph, and draws its XY chromaticity on the CIE1931 chromaticity graph, Compare the camera quality and effect.
