+image sensor indicating the sensor's sensitivity to light. The numbers are
+expressed in arithmetic scale, as per <xref linkend="iso12232" /> standard,
+where doubling the sensor sensitivity is represented by doubling the numerical
+ISO value. Applications should interpret the values as standard ISO values
+multiplied by 1000, e.g. control value 800 stands for ISO 0.8. Drivers will
+usually support only a subset of standard ISO values. The effect of setting

+control is set to a value other than <constant>V4L2_CID_ISO_SENSITIVITY_MANUAL
