EmguCV 调用摄像头c#代码转VB.NET请教

[o13763]

想用emguCV 来访问本地摄像头，在网上找了C#的代码，测试可行，转成VB.NET，其中有一行代码事件赋值代码出错。各位大神，，请问这一行用VB.NET该如何表示?
_capture.ImageGrabbed += ProcessFrame()
错误提示：错误1“Public Event ImageGrabbed(sender As Object, e As System.EventArgs)”是事件，不能直接调用。请使用“RaiseEvent”语句引发事件。

ProcessFrame事件：
Private Sub ProcessFrame(ByVal sender As String, e As EventArgs)
If (_capture IsNot Nothing And _capture.Ptr <> IntPtr.Zero) Then
_capture.Retrieve(_frame, 0)
ImageBox1.Image = _frame 'imageBox1显示控件
End If
End Sub

C#代码如下： using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; using Emgu.CV; using Emgu.CV.CvEnum; namespace WindowsFormsApplication1 { public partial class Form1 : Form { private VideoCapture _capture = null; private Mat _frame; public Form1() { InitializeComponent(); } private void ProcessFrame(object sender, EventArgs e) { if (_capture != null && _capture.Ptr != IntPtr.Zero) { _capture.Retrieve(_frame, 0); imageBox1.Image = _frame;//imageBox1显示控件 } } private void Form1_Load(object sender, EventArgs e) { } private void button1_Click(object sender, EventArgs e) { _capture = new VideoCapture(); _capture.ImageGrabbed += ProcessFrame; _frame = new Mat(); if (_capture != null) _capture.Start(); } } }

_capture.ImageGrabbed += ProcessFrame() 改成 AddHandler _capture.ImageGrabbed ，AddressOf ProcessFrame()
