41<h2>Return Values</h2>
42<div class="section">Returns the parallax at the location that is <SPAN class="argument">distance</SPAN> apart from a VGA image. The return value represents the translation of the left camera image based on the right camera image. This is measured in pixels. </div>
43<h2>Description</h2>
44    <div class="section">
45<p>Calculates the parallax at a specific distance from the stereo camera.</p><P>It uses the angles of view information stored in the <a href="../../../nn/camera/CTR/StereoCameraCalibrationData/Overview.html">nn::camera::CTR::StereoCameraCalibrationData</a> structure to calculate the parallax at <SPAN class="argument">distance</SPAN> away from the camera. There is a slight level of error in the parallax calculated by this function, due to errors in the angles of view information.
