  If the image looks faded and has bright horizontal lines on it, it's
well-known problem that happens because of the high load.

qcread | xv -

produces faded images on some boxes while

qcread > /tmp/mypic.ppm; xv /tmp/mypic.ppm

or

qcread | (sleep 2;xv -)

on the same box will produce clean images because the first line causes
xv being loaded/initialized at the same time when qcread is talking to
the camera.
