@Jae-Hee Park - why is a while loop needed? When the new data is received, draw the image then. The problem with the while loop is that your code will become "stuck" within it and no other action (GUI button press, callback, etc.) will be called unless you make the loop interruptible by introducing a pause or the drawnow like @Benjamin suggests.
