How to reduce the elapsed time on work to OpenCVFrameGrabber

[spy00798]

This code is Take picture with camera connnected in PC.

private static FrameGrabber grabber = null;

grabber = OpenCVFrameGrabber.createDefault(0);
                grabber.setImageWidth(1280);
                grabber.setImageHeight(720);
                grabber.start();
                if (grabber == null) {
                    return null;
                }
                frame = grabber.grab();
                FrameConverter converter = new Java2DFrameConverter();

                BufferedImage img = (BufferedImage) converter.convert(frame);

but this code running time is 13sec.
I want reduce time in 5sec.
Why spend time too long and What can I do?

Java2DFrameConverter is quite slow, don't use that

Java2DFrameConverter is quite slow, don't use that

but I need Frame convert to JPG Image. and VideoInputFrameGrabber is run fast but it's could not running by using SVP-USB500W02M device (maybe other also)
