The failure may be for example an electrical failure or an image The processing circuitry 102 is configured to detect a failure in a camera mirror quality failure in the camera mirror system that reduces the capability of operation for the camera mirror system 104. The failure prevents the user from using the camera mirror system 104, and forces the operator to stop the vehicle, or from travelling With the vehicle in a safe Way. The failure may be detected in operation data or fault code messages F received from the camera mirror system 104. id="p-70" id="p-70" id="p-70" id="p-70"

[0070] mounted by a mechanical arrn in a vehicle cab of the vehicle. The display configured to The camera mirror system 104 comprising a camera 106 and a display 108 display an image 140 captured by the camera 106. [0071] pixels that convert light to electric signals for capturing an image. Further, as applicable, the The camera 104 comprises optics 142 and a pixel array 144 of light sensitive camera 106 may include optical filters and other electrical and/or optical components. The camera 106 may comprise color sensitive pixels detecting incident light, Where the pixels may be configured to detect light in the visual spectrum. id="p-72" id="p-72" id="p-72" id="p-72"

[0072] controlled for displaying the image 140 captured by the camera 106. The pixels of the array The display 108 comprises an array 148 of color controllable pixels that are 11 148 have adjustable polarization where in one polarization mode the pixels reflect most of the incoming light and may operate as a mirror. The processing circuitry 102 is configured to control the display 108 to operate as a mirror. The display 108 may include a reflective polarizer film 117 part of the display stack, also optically referred to as a reflective polarizing mirror. A reflective polarizer film may be an optical film which allows transmission of one polarizing state and reflects another polarizing state. In mirror mode, with the display off, incoming light of one polarization is reflected, and in transmission mode when the display is on, the transmission axes of at least part of the emitted light from the display pixels and the reflective polarizer film is aligned to allow transmission of light from the pixels through the reflective polarizer film 117. id="p-73" id="p-73" id="p-73" id="p-73"

[0073] 110 to a level that allows operation of the mechanical arm 112 to move the display 108 Furthermore, the processing circuitry 102 is configured to lower a side window through the side window. For this, the processing circuitry 102 transmits a control message R to a control circuit 113 that controls the window 110 accordingly. id="p-74" id="p-74" id="p-74" id="p-74"

[0074] It is understood that the order of lowering the window 110 and control the display 108 to operate as a mirror is interchangeable. That is, either one of controlling the display and lowering the window may come first and be followed by the other one of controlling the display and lowering the window. id="p-75" id="p-75" id="p-75" id="p-75"

[0075] In some examples, processing circuitry may be configured to control actuation of the mechanical arm 112 to automatically move the display out through the side window 110 once the window is lowered. For example, one or more electric motors 150 or actuators may be controlled by the processing circuitry 102 so that the mechanical arm 112 moves the display 108. It is envisaged that, optionally, the mechanical arm is manually movable by an occupant of the vehicle to a location outside the side window. id="p-76" id="p-76" id="p-76" id="p-76"

[0076] The processing circuitry may further be configured to operate the mechanical arm 112 to adapt the angular orientation al, a2, of the display 108 with respect to the mechanical arm 112 to provide a visual field of view rearwards of the vehicle for a driver of the vehicle. That is, the display once configured as a mirror outside the window should provide a suitable rear field of view of the vehicle, similar to that of traditional side view mirrors. id="p-77" id="p-77" id="p-77" id="p-77"

[0077] The adaption of the angular orientation may be performed by the processing circuitry 102, where the angular orientation is deterrnined based on a driver reference position 152, e. g., in the driver°s seat 111 and a predeterrnined position of the display outside the 12 window. The predeterrnined position of the display 108 may be provided from the geometry and orientation of the mechanical arrn when positioned outside the window 110. The angular orientation is geometrically calculated. id="p-78" id="p-78" id="p-78" id="p-78"
