I think you are possibly doing this the wrong way. There is a canvas.translate() method which moves the canvas itself. This just sets the hardware to look at a translated location, so should be instantaneous plus or minus 1 nanosecond.
The downside is that you will need to draw the image to a larger sized bitmap than the screen, to cater for the movement you allow in your canvas.translate call, 19 pixels all around in your example.
