摘要

臺灣地小車多，在都會區停車不易，在道路旁能迅速倒車、停車， 甚為重要。然而，由於汽車構造會將駕駛與週遭環境阻隔，僅依靠現有 車用後視鏡，駕駛對車後安全距離難以正確握，常會預留過大空間，需 數度前進後退，才能停妥。 目前各家車廠提出之解決方案以加裝車載影像系統為最多，且各廠 牌裝置之位置與方式不一，如何才能有效幫助掌握車後狀況，本論文將 由設計端深入實際狀況改善其現有產品之缺陷，針對車載影像於各種照 度下進行不同之調整，以修正傳統車載影像於照度變化下所無法適時得 到最佳化影像之缺點，進而改善傳統車載影像使之更能適用於實際運 用，達到商品化目標，令使用者更能真正地發揮車載影像系統，安全的 保護人車即是車載影像的最大功能，所以提升車載影像的功能即是本論 文的首要重點。

並列摘要

Taiwan has limited space and lots of cars. It is uneasy to park a car in the
city therefore it’s important to back and park a car quickly. However, the
constitution of a car would separate the driver from the surrounding
environment. With the existing rear mirrors, the drivers cannot accurately
estimate the safety distance at the back of a car and they would hence keep
extra safety space. It results in driving a car back and forth several times in
order to park a car.
The current popular solution provided by the car companies is to add the
in-car image system and different brands has their ways and positions of the
installation. How to efficiently helping to understand the situation at the back
of a car becomes very important? The paper tried to improve the existing
products from the design end. It adjusted the the in-car image system in
various lux and tried to improve the poor result in the traditional the in-car
image system in changing lux. It further improves the in-car image system in
order to commercialize the product. The users of the product would then be
safely protected. The mission of this paper is to enhance the function of the
the in-car image system and hence to protect and drivers as well as the cars.
