光電眼鏡為一種結合頭戴式顯視器與影像感測器的輔助用具，其功能主要是利用影像處理的方式，讓使用者能看到已強化或已處理過的影像，並即時顯示在眼前，突破傳統光學眼鏡無法處理影像的缺點。由於光電眼鏡對影像即時性的需求極高，故設計電路時，必須以FPGA(field programmable gate array) 的多工特性與高工作頻率的特性來克服。本文將以光電眼鏡為例，介紹如何利用FPGA 來達成即時影像RGB raw data 的色彩轉換與LCOS (liquid crystal on silicon) 的顯像以及高頻電路設計時所需考量的導線參數。

Optoelectronic Eyeglasses is a supplementary apparatus which consists of head-type display and CCD module. With image processing technology, the image can be enhanced and displayed at the front of the user’s eye. Therefore, the drawbacks of optical eyeglasses can be overcome using the above described novel technology. Because real-time image processing is highly essential for Optoelectronic Eyeglasses, FPGA (field programmable gate array), which is multifunctional and can operate at high frequencies, is employed for the implementation of Optoelectronic Eyeglasses. This manuscript uses Optoelectronic Eyeglasses as an example to demonstrate how to employ FPGA for performing color processing on RGB raw data, displaying images on LCOS (liquid crystal on silicon), and examining high-frequency parameters of signal wires.
