From fc162a099e7b34bfe3501028c919ff5d43e5e3d3 Mon Sep 17 00:00:00 2001 From: Sylwester Nawrocki Date: Wed, 2 May 2012 06:24:33 -0300 Subject: [media] V4L: Add camera 3A lock control The V4L2_CID_3A_LOCK bitmask control allows applications to pause or resume the automatic exposure, focus and wite balance adjustments. It can be used, for example, to lock the 3A adjustments right before a still image is captured, for pre-focus, etc. The applications can control each of the algorithms independently, through a corresponding control bit, if driver allows that.
