How to create an rectangle area when capturing ( camera )

I would like to achieve something like this:
So the that the only thing you capture and process is the area in the rectangle.
I need this because I want to do some OCR and I don't want the whole screen.

Maybe help you this source, (draw a bounding box on top of a camera preview to capture part of the image)

If you need more information let me know.

You can increase/decrease camera's fov.

Android game in surfaceview lagg spikes

guys. I'm playing around with making my very first Android game, but stumbled into a problem. The framerate seems to have random lag spikes. If I comment the background(s) out the framerate gets much smoother. I've looked around SO and can't find anything to solve my problems. I have a feeling it has something to do with allocating a specific amount of time every time I draw, but I don't know how to properly implement such a feature. Any suggestions? Btw, tryed hardware ac, anti etc.
This is the class that starts the surfaceview :
package com.example.glassrunner;
Imports Here
public class Game extends Activity
{
MySurfaceView mySurfaceView;
public SoundPool spool;
private int soundID;
int length=0;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
this.setVolumeControlStream(AudioManager.STREAM_MUSIC);
mySurfaceView = new MySurfaceView(this);
setContentView(mySurfaceView);
}
#Override
protected void onResume()
{
// TODO Auto-generated method stub
super.onResume();
mySurfaceView.onResumeMySurfaceView();
}
#Override

{
// TODO Auto-generated method stub
super.onPause();
mySurfaceView.onPauseMySurfaceView();

#Override

I think your problem might be actually the moving part. Your just drawing too much stuff, and the surfaceView is not meant for that.

Ontouch() isn't work with custom view?

I have a class it extends "View" and Implement "OnTouchListener" so it's will override ontouch method automatically but this method not work. I try to debug by put breakpoint in this method but it isn't called.

remove implements OnTouchListener and override the method:
public boolean onTouch(MotionEvent event)
