Yes, there is. Video IS aligns consecutive frames by using a
larger-than-needed sensors and using different parts of it as the
image moves. If the image moves to the left two pixels then the video
camera will detect the motion and take the image from the area of the
sensor that is two pixels to the left. Nothing actually moves and so
it's all electronic and cheap to make.
But a photo camera only takes one shot at a time. In order to
stablize and image either the sensor has to move or a lens has to
move. That makes it expensive.
