AM 3517 WINCE 7 capturetest APPカメラ機器情報取得
16669 ワード
AM 3517 wince 7 camera driverをデバッグしたところ、TIのCAMERAテストプログラムCaptureTestの実行時に次の情報が印刷されていることがわかりました
これらの情報はどこからどのように印刷されたのでしょうか.
WinMainで
この2つの文が呼び出されました IAMStreamConfigインタフェース、祥は前の1篇の紹介を見ますhttp://blog.csdn.net/zhangjikuan/article/details/42462715
これらの情報はドライバでどのように定義されているのでしょうか.
cameraPDDParams.hで解像度サイズが定義されています
上の配列はどこで呼び出されたのですかcameraDrvPdd.cppは配列中のすべてのメンバーをm_に割り当てましたpModeVideoFormat[CAPTURE].pCsDataRangeVideo[i]
実はpreviewとskillにも与えられています
cameraDrvPdd.hで定義したm_pModeVideoFormat
//All the Video Formats supported by all the pins
PPINVIDEOFORMAT m_pModeVideoFormat;
