on average and cover the complete area viewed by the camera; the camera shall view no other objects than the test pattern.

              6.2.2.2.1.2. The camera shall be hit by a (simulated sun) light of 40 klx, spanning an angle between 0.6 and 0.9° with an elevation angle of 10° (directly or indirectly via a mirror) removed from the optical axis of the sensor.

              The light source shall:

              (a) Have a spectrum D65 with a tolerance of ±1,500 K;

              (b) Be homogeneous in space and time within a tolerance of 2 klx.

              The emission of the light source in infrared shall be negligible.

              6.2.2.2.1.3. There shall be no ambient illumination of the monitor during the test.

              6.2.2.2.1.4. An example of the set-up is given in the Figure A below.

       3:  Mirror.
       4:  High intensity light.
       5:  Camera.
       6:  Monitor.

              6.2.2.2.2. The monitor shall render a minimum contrast under various light conditions as specified by ISO 15008:2003.

              6.2.2.2.3. It shall be possible to adjust the average luminance of the monitor either manually or automatically to the ambient conditions.

              6.2.2.2.4. The measurements for the luminance contrast of the monitor shall be carried out according to ISO 15008:2009.

              6.2.2.3. Functional requirements for camera-monitor devices of Classes I to IV (see Annex 12).

              Unless otherwise specified in this Regulation, the definitions and symbols used in paragraph 6.2.2.3. are in accordance with ISO 16505:2015,
              Chapters 3 and 4.

              Unless otherwise specified in this Regulation, the requirements given in paragraph 6.2.2.3. shall be verified according to the test procedures given in ISO 16505:2015, Chapter 7, where available.

              6.2.2.3.1. Luminance adjustment

              It shall be possible to adjust the average luminance of the monitor either manually or automatically to the ambient conditions.

              6.2.2.3.2. Operating readiness (System availability)

              If the system is not operational (e.g. CMS failure), it shall be indicated to the driver by i.e. warning indication, display information, absence of status indicator. The operator's manual shall explain the information indicated.

              6.2.2.3.3. Image quality

              6.2.2.3.3.1. Monitor isotropy

              The monitor shall conform to optical requirements over the range of viewing directions that is specified in the following paragraphs.

              6.2.2.3.3.1.1. Directional uniformity

              When driven by an artificial 70 per cent grey-scale image, the deviation of the monitor luminance from the luminance white level  with specific viewing direction (Ɵ, ϕ) = (Ɵmonitor/D, ϕ monitor/D) shall be such that the ratio relative to the luminance white level for the same specific viewing direction L(Ɵmonitor/D, ϕ monitor/D) does not exceed 35 per cent of the luminance white level for the monitor standard isotropy range and shall not exceed 50 per cent
