想請問各位大大：

目前我用DOMINO Alpha 2擷取卡所提供的範例可以秀出影像了，但我要作後續的處理，如作二值化等，所以第一我需要知道影像擷取進來的用的參數名稱，第二我要如何才能從連續的影像中改成一張一張地處理。

主要程式如下：
CProject1Doc::CProject1Doc()
{
// TODO: add one-time construction code here
m_Channel = 0 ;
m_pCurrent = NULL ;
m_SizeX = 0;
m_SizeY = 0;
m_BufferPitch = m_SizeX;
m_bScreenRefreshCompleted = TRUE;
}
CProject1Doc::~CProject1Doc()
{
// Set the channel to IDLE before deleting it
McSetParamInt (m_Channel, MC_ChannelState, MC_ChannelState_IDLE);
// Delete the channel
McDelete (m_Channel);
}
BOOL CProject1Doc::OnNewDocument()
{
if (!CDocument::OnNewDocument())
return FALSE;
// Show scope of the sample program
MessageBox(NULL, "\

// Create a channel using the X connector
McCreate (MC_CHANNEL_ALPHA_X, &m_Channel);
McSetParamInt (m_Channel, MC_DriverIndex, 0);
// Associate a camera and its configuration to the channel
// Please modify the following line to adapt the sample program

McSetParamStr(m_Channel, MC_CamFile, "XC-HR70_P30SM");
// McSetParamStr(m_Channel, MC_CamFile, "CV-M50C_P50RA.cam");
// The acquisition mode is SNAPSHOT on an Alpha board and has not to be set
// Configure the triggering mode
McSetParamInt (m_Channel, MC_TrigMode, MC_TrigMode_IMMEDIATE);
McSetParamInt (m_Channel, MC_NextTrigMode, MC_NextTrigMode_REPEAT);
// Configure number of acquisition
McSetParamInt (m_Channel, MC_SeqLength_Fr, MC_INDETERMINATE);
// Retrieve image dimensions
McGetParamInt (m_Channel, MC_ImageSizeX, &m_SizeX);
McGetParamInt (m_Channel, MC_ImageSizeY, &m_SizeY);
McGetParamInt (m_Channel, MC_BufferPitch, &m_BufferPitch);
// The memory allocation for the images is automatically done by Multicam when activating the channel.
// We only set the number of surfaces to be created by MultiCam.
McSetParamInt (m_Channel, MC_SurfaceCount, EURESYS_SURFACE_COUNT);
// Enable MultiCam signals
McSetParamInt(m_Channel, MC_SignalEnable MC_SIG_SURFACE_PROCESSING, MC_SignalEnable_ON);
// Register the callback function
McRegisterCallback(m_Channel, GlobalCallback, this);

return TRUE;

現在回復不曉得會不會太晚了,
第一我需要知道影像擷取進來的用的參數名稱
Ans:影像取得的address在您的code,McGetParamInt (SigInfo->SignalInfo, MC_SurfaceAddr, (PINT32) &m_pCurrent);
其中m_pCurrent就是影像的起點的address,長度就依你設定的寬*高.

第二我要如何才能從連續的影像中改成一張一張地處理。
Ans:將McSetParamInt (m_Channel, MC_ChannelState, MC_ChannelState_ACTIVE);
改為McSetParamInt(m_Channel, MC_SeqLength_Fr, MC_HIGH_PART);,就會grab一張影像,要改回去連續取像,再下McSetParamInt (m_Channel, MC_ChannelState, MC_ChannelState_ACTIVE);

建議:
建議你用他的工具處理影像會比較方便(不過要買licence)
EC24Image1->SetImagePointer(m_SizeX,m_SizeY,(long)m_pCurrent,0);
這樣你就可以用他的元件做一些如二直化,PATTERN MATCH.OCR........
