43<h2>Description</h2>
44    <div class="section">
45<p>Sets the noise filter.</p><P>
46				If a camera's noise filter is enabled, and the screen changes from bright to dark or vice-versa, the camera module automatically eliminates noise by smoothing and other techniques. The use of the stereo camera can therefore cause only one of the images to appear blurry. In order to avoid such situations, use this function to disable the noise filter for both cameras.
47			</P><P>
48				The default value is <CODE>true</CODE> for all cameras.
49			</P><p>Note that this function may block internally for an extended period if a camera is restarting.</p></div>
