1. A vehicular vision system, the vehicular vision system comprising:
a camera disposed at a vehicle equipped with the vehicular vision system, the camera viewing exterior of the vehicle and capturing image data;
an electronic control unit (ECU) comprising electronic circuitry and associated software;
wherein the electronic circuitry of the ECU comprises an image processor for processing image data captured by the camera;
a video display disposed in the vehicle and viewable by a driver of the vehicle, wherein the video display is operable to display video images derived from image data captured by the camera, and wherein the video display is divided into a plurality of display portions, and wherein each display portion of the plurality of display portions displays a different respective portion of the video images, and wherein each display portion of the plurality of display portions does not overlap with any other display portion of the plurality of display portions;
wherein the vehicular vision system, responsive to processing by the image processor of image data captured by the camera, displays video images at the plurality of display portions of the video display;
wherein graphic overlay data stored in memory represents a plurality of graphic overlay portions, and wherein each graphic overlay portion of the plurality of graphic overlay portions is associated with only a single respective display portion of the plurality of display portions, and wherein each graphic overlay portion is associated with a respective driving condition of a plurality of driving conditions; and
wherein, responsive to an occurrence of one of the plurality of driving conditions, the vehicular vision system (i) retrieves the graphic overlay data from memory, (ii) displays each graphic overlay portion of the plurality of graphic overlay portions at the associated single respective display portion of the plurality of display portions and (iii) adjusts a transparency of at least one of the displayed graphic overlay portions such that each displayed graphic overlay portion associated with the one of the plurality of driving conditions has a respective transparency that is less than a respective transparency of each displayed graphic overlay portion not associated with the one of the plurality of driving conditions, such that each displayed graphic overlay associated with the one of the plurality of driving conditions is viewable by the driver of the vehicle when viewing the video display and each displayed graphic overlay portion not associated with the one of the plurality of driving conditions is not viewable by the driver of the vehicle when viewing the video display.
