Subject: [PATCH 3/6] media: ov5640: Disable transparent feature for test pattern
Date: Fri, 18 Jan 2019 16:52:03 +0800 [thread overview]
Message-ID: <20190118085206.2598-4-wens@csie.org> (raw)
In-Reply-To: <20190118085206.2598-1-wens@csie.org>
The transparent feature for test patterns blends the test pattern with
an actual captured image. This makes the result non-static, subject to
changes in the sensor's field of view.
Test patterns should be predictable and deterministic, even if they are
dynamic patterns. Disable the transparent feature of the test pattern.
