Claim 9:
10. A vehicular driving assist system, the vehicular driving assist system comprising:
a camera disposed at an interior rearview mirror of a vehicle equipped with the vehicular driving assist system and having a field of view of the interior of the vehicle, the camera capturing image data;
wherein the camera comprises a CMOS imaging array and a lens, and wherein the CMOS imaging array comprises at least one million photosensors arranged in rows and columns;
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 to detect presence of objects in the field of view of the camera;
wherein the vehicular driving assist system, responsive to processing by the image processor of image data captured by the camera, determines presence of a driver of the vehicle;
wherein the vehicular driving assist system, responsive to processing by the image processor of image data captured by the camera, determines an intensity of glare light;
wherein the vehicular driving assist system, responsive to determining that intensity of the glare light is greater than a threshold level, at least partially dims the interior rearview mirror;
wherein the vehicular driving assist system determines a portion of the interior rearview mirror that is reflecting glare light toward the driver of the vehicle, and wherein the vehicular driving assist system, responsive to determining the portion of the interior rearview mirror that is reflecting the glare light, dims the portion of the interior rearview mirror that is reflecting the glare light while not dimming other portions of the interior rearview mirror that are not reflecting the glare light;
wherein the lens is disposed at the CMOS imaging array with a centerline of the lens that does not pass through a center of the CMOS imaging array, and wherein, with the camera disposed at the interior rearview mirror, a center region of the lens is disposed at and images at a lower region of the CMOS imaging array and an upper region of the lens images at the center region of the CMOS imaging array; and
wherein the vehicular driving assist system, responsive to movement of the interior rearview mirror of the vehicle, adjusts a position of the lens relative to the CMOS imaging array based on the movement of the interior rearview mirror.
