how to draw a bitmap larger than the canvas in android -

I am developing an application in which the camera preview is displayed continuously when the user wants it, Takes a picture with it and later stores it in a bitmap image to attract it.

The problem is that the canvas is portraying the preview all the time, and when you attract the bitmap of the image you made before, the canvas pulls it incorrectly, because I think it's a bitmap canvas More than because the bitmap does not have a resolution of the camera and the canvas is not.

How can I fix this? I need to attract Bitmap properly in the canvas.

Thanks
