Progress bar , timer, background worker not working in my windows application

hi all
i have windows dot net application in which i m capturing image and displaying it in picturebox.
but after capturing i am doing some processing on that image it takes some time
now i want to show progress bar at the bottom of my form until the image is displayed.
i have used background worker also but it is not firing the event:

private void backgroundWorker1_ProgressChanged(object sender, ProgressChangedEventArgs e)
       {
           progressBar1.Value = e.ProgressPercentage;
           // Set the text.
           this.Text = e.ProgressPercentage.ToString();
       }

i have also used the timer for progress bar but that time gets activated after the processing of image.

private void timer1_Tick(object sender, EventArgs e)
       {
           progressBar1.Value = 10;
       }

this is my function from which i want to start progress bar.

private void btnCapture_Click(object sender, EventArgs e)
       {
//with timer
           timer1.Start();
           timer1.Interval = 100;

//or with background worker
backgroundWorker1.RunWorkerAsync();

           try
           {
               btnLogIn.Enabled = true;
               btnLogOff.Enabled = false;
               lblErrorMsg.Text = "";
               if (txtUserName.Text != "")
               {
                   savingPath= "C:/Inspira/SSO/SSOImage.bmp";
                   if (File.Exists(savingPath))
                   {
                       File.Delete(savingPath);
                   }
                   SSOComp.SSO sosObj = new SSOComp.SSO();
                   string sucessStatus = sosObj.Capture(savingPath);
                   if (File.Exists(savingPath))
                   {
                       lblErrorMsg.ForeColor = Color.Green;
                      
                       PicBoxFinger.ImageLocation = savingPath;
                       //after this i want to stop progress bar .                    
                   }
                   else
                   {
                       lblErrorMsg.ForeColor = Color.Red;
                       lblErrorMsg.Text = "Image not Captutred.";
                   }
               }
               else
               {
                   lblErrorMsg.ForeColor = Color.Red;
                   lblErrorMsg.Text = "Please Enter User Name.";
                
               }


              }
           catch (Exception ex)
           {
               lblErrorMsg.Text = ex.Message;
           }
       }</pre>

and background worker code:

private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
     {
         for (int i = 1; i <= 100; i++)
         {
             // Wait 100 milliseconds.
             Thread.Sleep(1000);
             // Report progress.
             backgroundWorker1.ReportProgress(i+10);
         }
     }

i want to start the progress bar on capture click till the picture is displayed in picturebox.
