+    <para>
+This format describes histogram data generated by the Renesas R-Car VSP1 1-D
+Histogram (HGO) engine.
+    </para>
+    <para>
+The VSP1 HGO is a histogram computation engine that can operate on RGB, YCrCb
+or HSV data. It operates on a possibly cropped and subsampled input image and
+computes the minimum, maximum and sum of all pixels as well as per-channel
+histograms.
+    </para>
+The HGO can compute histograms independently per channel, on the maximum of the
+three channels (RGB data only) or on the Y channel only (YCbCr only). It can
+additionally output the histogram with 64 or 256 bins, resulting in four
+possible modes of operation.
+      <itemizedlist>

+	  <para>
+	    In <emphasis>64 bins normal mode</emphasis>, the HGO operates

+	  <para>
+	    In <emphasis>64 bins maximum mode</emphasis>, the HGO operates

+	</listitem>
+	<listitem>
+	  <para>
+	    In <emphasis>256 bins normal mode</emphasis>, the HGO operates
