Subject: [PATCH v2 1/4] v4l2: Add camera zoom controls
Date: Fri, 12 Dec 2008 14:04:10 +0100 [thread overview]
Message-ID: <200812121404.10640.laurent.pinchart@skynet.be> (raw)
In-Reply-To: <200812121401.55277.laurent.pinchart@skynet.be>
The zoom controls move the zoom lens group to a an absolute position, as a
relative displacement or at a given speed until reaching physical device
limits. Positive values move the zoom lens group towards the telephoto
direction, negative values towards the wide-angle direction.
