I am still learning the syntax and functions of open CV.

The idea is when I press keyboard it will read the camera and display it; but I never get current picture. It seems there are a buffer of 3 or 4 photos. The image at which time I hit the keyboard shows after I hit another 2or 3 times.

2. import hypermedia.video.*;
3. OpenCV opencv;
4. 
   
5. void setup() {
6.     size( 100  ,100 );
7.     opencv = new OpenCV( this );
8.     opencv.capture( width, height );                   // open video stream
9. }
10. 
    
11. void draw() {
12. }
13. 
    
14. void keyPressed() {
15.      opencv.read();
16.      image(opencv.image(),0,0);
17.      println( opencv.pixels() );
18. }
