Sumio Morioka / Mbed 2 deprecated if201411_section10

Sample code of section 10 in Nov 2014 issue of the Interface Magazine, published by CQ publishing in Japan. CQ出版社インターフェース誌 2014年11月号10章に掲載のサンプルコードです． LPC1768にトラ技OV7670モジュールを接続したうえで，省メモリ画像処理（色による簡易顔検出）を行う事例です．画像フレームバッファを確保できないとき，ストリーム処理で画像を加工するのがテーマです．このコードのうちカメラ制御部には，Sadaei Osakabe氏のコードを流用させていただいています．
