  • Publication number: 20120120239
    Abstract: A forward facing imaging system for a vehicle includes an interior rearview mirror assembly mounted at an interior portion of a vehicle and a camera disposed at the interior rearview mirror assembly. The camera has a forward field of view through a windshield of the vehicle. The camera captures image data and captured image data is recorded by a recording system. During operation of the vehicle, the recording system records image data, as it is captured over a given period of operation of the vehicle, in a closed-loop fashion onto electronic memory. Image data, as captured by the camera, is processed by an image processor in order to determine the presence of at least one object forward of the equipped vehicle.

  • Publication number: 20120086808
    Abstract: A video mirror system for a vehicle includes an interior rearview mirror assembly with an electrochromic reflective element. The reflective element has an electrochromic medium disposed between a first substrate and a second substrate and has a transflective third-surface mirror reflector. A video display is disposed to the rear of the reflective element and emits light when actuated that passes through the transflective mirror reflector. The video display includes a thin film transistor video screen that is back lit by a plurality of white light emitting light emitting diodes that are operable by a control. The control includes DC to DC conversion circuitry that includes circuitry for converting an ignition voltage of the equipped vehicle to a lower voltage that is closer to the forward voltage applied across individual white light emitting light emitting diodes of the plurality of white light emitting light emitting diodes than the ignition voltage.
