+title: Rockchip Image Enhancement Processor (IEP)
+
+description:
+    Rockchip IEP supports various image enhancement operations for YUV and RGB domains.
+    Deinterlacing, spatial and temporal sampling noise reduction are supported by the
+    YUV block. Gamma adjustment, edge enhancement, detail enhancement are supported in
+    the RGB block. Brightness, Saturation, Contrast, Hue adjustment is supported for
+    both domains. Furthermore it supports converting RGB to YUV / YUV to RGB.
