title: Camera resolution openCV
body: <p>I'am currently working on an Android application and I need to be able to :</p>
  
  <p>Find square on a preview Camera. that part is working.
  The problem that I have is, in order to be able to find these square on the Camera preview, I need to change my Camera resolution to 800x600 in order to have something smooth.</p>
  
  <p>What I want is : As soon as I hit my button I want to capture the image in a specific resolution (1920x1080 for example). So basically the preview have to be in 800x600 but the capture have to be in 1920x1080.</p>
  
  <p>I'am using openCV to process my camera view on live.</p>
