Noriaki Mitsunaga / Mbed 2 deprecated DigiCam

This is an digital video camera program using NKK\'s oLED swtich and 4D Systems\' uCam serial camera. It takes image from the uCam and displays on the IS-C15 switch. Some image processing demos are included. This program uses FatFileSytem, SDFileSystem, and TextLCD library. See http://www.youtube.com/watch?v=fqHTaCRHyQs for how it works. CQ出版社の「mbed/ARM活用事例」第10章シリアル接続カメラと有機ELディスプレイ内蔵スイッチで作るmbedディジタル・カメラの作例です。動作の様子は http://www.youtube.com/watch?v=fqHTaCRHyQs で見れます。

Dependencies: TextLCD mbed SDFileSystem
