Multifunctional rearward viewing camera system

A vehicular vision system, the vehicular vision system comprising:

• a rear-viewing camera disposed at a vehicle equipped with the vehicular vision system, the rear-viewing camera viewing at least rearward of the equipped vehicle;
• wherein the rear-viewing camera comprises a CMOS imaging array having at least one million photosensing elements arranged in rows and columns;
• wherein the CMOS imaging array of the rear-viewing camera is operable to capture frames of image data;
• an interior electro-optic rearview mirror assembly, wherein the interior electro-optic rearview mirror assembly comprises a mirror head accommodating an electro-optic mirror reflective element;
• wherein the mirror head is adjustable about a mounting base that is configured to mount the interior electro-optic rearview mirror assembly at an interior portion of the equipped vehicle;
• an electronic control unit (ECU) disposed at the equipped vehicle separate from the mirror head, wherein the ECU includes a processor operable to process frames of image data captured by the CMOS imaging array of the rear-viewing camera;
• a video display device disposed behind the electro-optic mirror reflective element, wherein the video display device includes a video display screen operable to display video images;
• wherein the interior electro-optic rearview mirror assembly comprises a dual-mode interior electro-optic rearview mirror assembly;
• wherein, with the interior electro-optic rearview mirror assembly mounted at the interior portion of the equipped vehicle, and with the dual-mode interior electro-optic rearview mirror assembly operating in a mirror mode, the video display device does not display video images at the video display screen and a driver of the equipped vehicle views rearward via reflection at the electro-optic mirror reflective element;
• wherein, with the interior electro-optic rearview mirror assembly mounted at the interior portion of the equipped vehicle, and with the dual-mode interior electro-optic rearview mirror assembly operating in a display mode, the video display device displays at the video display screen video images derived from frames of image data by the CMOS imaging array of the rear-viewing camera for viewing by the driver of the equipped vehicle;
• wherein, with the interior electro-optic rearview mirror assembly mounted at the interior portion of the equipped vehicle, the ECU determines, via processing by the processor of frames of image data captured by the CMOS imaging array of the rear-viewing camera, glaring light emanating from a rearward approaching vehicle rearward of the equipped vehicle;
• and
• wherein the ECU controls dimming of the electro-optic mirror reflective element based at least on part on the determined glaring light.

A vehicular vision system, the vehicular vision system comprising:

• a rear backup camera disposed at a vehicle equipped with the vehicular vision system, the rear backup camera viewing at least rearward of the equipped vehicle;
• wherein the rear backup camera comprises a CMOS imaging array having at least one million photosensing elements arranged in rows and columns;
• wherein the CMOS imaging array of the rear backup camera is operable to capture frames of image data, and wherein the CMOS imaging array has at least three million photosensing elements arranged in rows and columns;
• wherein the CMOS imaging array of the rear backup camera captures frames of image data during a reversing maneuver of the equipped vehicle, and wherein video images derived from frames of image data captured during the reversing maneuver are displayed at a video display screen within the equipped vehicle for viewing by a driver of the equipped vehicle during the reversing maneuver;
• an electro-optic rearview mirror assembly configured to mount at the equipped vehicle, wherein the electro-optic rearview mirror assembly comprises an electro-optic mirror reflective element;
• an electronic control unit (ECU) disposed at the equipped vehicle separate from the electro-optic rearview mirror assembly, wherein the ECU includes a processor operable to process frames of image data captured by the CMOS imaging array of the rear backup camera;
• wherein, with the electro-optic rearview mirror assembly mounted at the equipped vehicle, the ECU determines, via processing by the processor of frames of image data captured by the CMOS imaging array of the rear backup camera, glaring light emanating from a rearward approaching vehicle rearward of the equipped vehicle;
• and
• wherein the ECU controls dimming of the electro-optic mirror reflective element based at least on part on the determined glaring light.
