摘要

研究運用不同的曝光控制技術製作不同色彩描述檔，並藉由使用這些色彩描述檔以探討其對色彩複製準確度的影響。實驗設計包含在數位相機拍攝時，透過閃燈電筒出力值的調整以及不同光圈設定兩種曝光控制技術，再據以製作色彩描述檔以複製色彩，最後與導表上影像色塊實際值進行色差比較，希望所得之結果能做為數位相機色彩管理效能之參考依據。

This study explores the influence of various exposure control techniques in digital photography to the color reproduction quality in color management process on digital camera. The exposure is controlled by changing the output power and aperture settings. The color reproduction quality is evaluated by the color difference between the original and reproduced color targets. The results can serve as the benchmark reference for color management workflow in digital camera.
