39<h2>Description</h2>
40    <div class="section">
41<p>Sets the standard conversion coefficients.</p><p>
42The initial value is not suitable for conversion, so you must specify the appropriate conversion coefficient for your intended purpose.
43            </p><p>
44To convert the YUV data that is captured by the CTR camera, the most appropriate conversion result can be obtained by using the conversion coefficient obtained by calling the <CODE>nn::camera::CTR::GetSuitableY2rStandardCoefficient</CODE> function.
45            </p><p>
46Use <CODE>COEFFICIENT_ITU_R_BT_601</CODE> if you have used the JPEG library to output in YUV format images that were captured using the CTR system's cameras and encoded using the JPEG library. You can obtain similar results if you had output to RGB directly from the JPEG library.
47            </p><p>
48However, because the precision of the calculations is different, you may not get the exact same results.
