First check if you are calling dispose() on Graphics2D created via BufferedImage.createGraphics(), then check if you are calling flush() method on BufferedImage you have created when you do not want to use this image any more. If this won't help, you can try to use ready solution, e.g. utilize this project:

https://github.com/sarxos/webcam-capture

Code example (take picture from webcam and save in test.png file):

Webcam webcam = Webcam.getDefault();
BufferedImage image = webcam.getImage();
ImageIO.write(image, "PNG", new File("test.png"));

With this library you don't need to dispose graphics nor flush buffered image after it is not used any more - underlying driver will do it for you.
