the requirements concerning fields of vision or fields of detection.
         15.4.1.4. Devices for means of rear visibility or detection shall be fitted in such a way that the devices do not move so as significantly to change the field of vision or detection as measured or vibrate to an extent which would cause the driver to misinterpret the nature of the image perceived.
         16. Requirements for rear-view camera system
         16.1. Default view
         In default view the RVCS shall show the field of view at least as defined in paragraph 15.2.
         The RVCS must default to the rear-view image at the beginning of each backing event regardless of any modifications to the field of view that the driver has previously selected.
         16.1.1. Object size
         When the Rear-view image is measured in accordance with the paragraphs 3. of Annex 9, the calculated visual angle subtended by the horizontal width of:
              (a)                    All three test objects at the last row specified in 15.2 shall average not less than 5 minutes of arc; and
              (b)                   Each individual test object shall not be less than 3 minutes of arc.
         16.1.1.1. Luminance and contrast adjustment
         If manual adjustment is provided, the operator's manual shall provide information on how to change the luminance/contrast.
         16.1.1.2. Overlay requirements within the required field of vision
         Overlays shall display only rearward driving-related visual information or safety-related information. Overlays for other purposes of information in the required field of vision are not allowed.
         Manually activated overlays are allowed, only when the driver needs to activate a rearward driving-related function or safety-related function (e.g. cleaning of the lens or activation of trailer hitch view) or requires specific information in such an environment. The driver may have an option to close the overlay.
         16.1.1.3. Deactivation
         The rear-view image shall remain visible during the backing event until either, the driver modifies the view, or the vehicle direction selector is no longer in the reverse position or the backing event is finished.
         Modifying the view means to switch to any other camera views.
         The view can be manually switched off when the vehicle is not moving rearward.
         The system may be switched off when the vehicle detects a coupling by means of a coupling device.
         16.1.1.4. Automatic change of view
         When there is a risk of collision, the field of view may change and focus on the collision area. It shall be demonstrated to the Technical Service that this change of view increases the safety.
         When the vehicle is not driving straight, the field of view may change following the vehicle trajectory.
         16.1.2. Operating readiness (System availability)
         Non-operation of the system shall be recognizable to the driver (e.g. RVCS failure by, i.e. warning indication, display information,
