摘要

國研院儀器科技研究中心開發一套嵌入式自動化影像感測器訊雜比量測系統，其特點為整合嵌入式系統並可客製化設計使用者所需之影像感測器參數。嵌入式自動化影像感測器參數量測系統包括了NI CompactRIO嵌入式系統、積分球參數控制與光源訊號回饋顯示。NI CompactRIO嵌入式系統可以達到獨立執行效能，並可自動控制積分球參數控制，其中包含了光源大小與入光量控制，另外也可自動回饋光源資料。透過本系統可以輕易的量測到影像感測器資料並計算出影像像素訊雜比參數，文中詳細指出相關系統設計與量測情形，以提供國內相關領域的整合與應用。

The automatic signal-to-noise ratio (SNR) measurement system was carried out in this research. The embedded system and customized design were also integrated in this system. The automatic SNR measurement system consists of a NI CompactRIO Embedded system, parameters of integrating board control, a light source feedback and a data display. The NI CompactRIO embedded system can control and measure several parameters which include light source, image data, as well as SNR data. The article also introduces the system structure, design, and measurement results that we hope providing those information for more applications in related industries.
