1. A vehicular display system, comprising:

  • a display monitor;

    a camera mounted at a rear of a vehicle equipped with the vehicular display system, wherein the camera has a field of view rearward of the equipped vehicle and is operable to capture image data and to generate a video signal indicative of the captured image data;

    a controller receiving an input indicative of the video signal and, responsive thereto, providing video information for displaying video images on the display monitor;

    wherein, responsive to the input and responsive to vehicle speed data of the equipped vehicle being indicative of the equipped vehicle moving rearwardly at a speed greater than zero, the controller is operable to perform an integrity check to ensure that video information provided to the display monitor is not compromised;

    wherein the integrity check determines that video information provided to the display monitor is compromised via a determination, when the equipped vehicle is moving in reverse, that video information provided to the display monitor comprises a frozen image;

    wherein, responsive to the controller determining that video information provided to the display monitor comprises a frozen image, the controller generates an alert to a driver of the equipped vehicle; and

    wherein a threshold level of change in captured image data at which the video information is determined to comprise a frozen image varies with the vehicle speed.
