+digital cameras differ from larger, more expensive, cameras (`DSLRs`_) in a
 few respects. The most important of these, for understanding the Pi's camera,
 is that many mobile cameras (including the Pi's camera module) use a `rolling
 shutter`_ to capture images. When the camera needs to capture an image, it
 reads out pixels from the sensor a row at a time rather than capturing all
 pixel values at once.

 covers the sensor.  Hence in a DSLR the procedure for capturing an image is to
 open the shutter, letting the sensor "view" the scene, close the shutter, then

 The notion that the camera is effectively idle until we tell it to capture a
 frame is also misleading. Don't think of the camera as a still image camera.
