Abstract:The design and realization for the embedded digital camera based on Linux was introduced in this paper. This design is using Linux system kernel. The whole system hardware including: S5PV210 development board as a tester lord, TFT-LCD touch screen button as a controller,use TF card as a picture storage media. The Software design is more complex. First build a good environment for the development board, write the main program. Then write the program for the touch screen driver and the trigger function for various functions of the digital camera. Last complete the user interface. The touch screen of system can be operation this digital camera, and realize the various functions. System operation is reliable in practical application, and satisfied demand of system design. It affords a reference for Embedded digital camera.

1 引 言
數碼相機,英文名“Digital Camera”,是現在通信、計算機產業、照相機產業高速發展的產物。隨著電信、計算機的普及和家庭化,數碼相機作為計算機的圖像輸入設備,不僅能采集靜止圖像,而且能采集視頻圖像和音頻信號,便于計算機存儲和處理,容易實現網絡傳輸,其應用領域日益廣泛。
新款數碼相機不斷推出新的概念,一是它代表了一種全新的生活方式;二是數碼相機本身就是一種區別于傳統相機的新事物;三是數碼相機有著其前瞻性、時尚性特點;四是它存在的基礎就是最新的科技技術。
本論文針對基于Linux的嵌入式數碼相機的設計和實現進行了研究,設計主要任務是要實現數碼相機的基本功能,即對采集圖像的實時顯示、瀏覽控制、存儲等。……
