Vehicular driver and passenger monitoring system at interior mirror

A vehicular cabin monitoring system, the vehicular cabin monitoring system comprising:an interior rearview mirror assembly comprises a mirror head adjustable about a mounting structure, wherein the mounting structure is configured to mount the interior rearview mirror assembly at an interior portion of an interior cabin of a vehicle;wherein the mirror head accommodates a mirror reflective element, a first lens and a second lens;wherein a camera is accommodated by the mirror head, and wherein, with the interior rearview mirror assembly mounted at the interior portion of the interior cabin of the vehicle, the camera views within the interior cabin of the vehicle;wherein the camera viewing within the interior cabin of the vehicle has a first field of view and a second field of view;wherein a first region within the interior cabin of the vehicle is within the first field of view of the camera, and wherein a second region within the interior cabin of the vehicle is within the second field of view of the camera, and wherein the second region of the interior cabin of the vehicle is different from the first region of the interior cabin of the vehicle;

• wherein the camera views the first region within the interior cabin of the vehicle via the first lens, and wherein the camera views the second region within the interior cabin of the vehicle via the second lens;
• wherein an optical element is accommodated by the mirror head, and wherein light that is representative of the first region (i) passes through the first lens to be incident at the optical element and (ii) is directed by the optical element toward the camera, and wherein light that is representative of the second region (a) passes through the second lens to be incident at the optical element and (b) is directed by the optical element toward the camera;
• wherein at least one selected from the group consisting of (i) the first lens comprises a negative lens having a field of view with a width of at least 40 degrees and (ii) the second lens comprises a negative lens having a field of view with a width of at least 40 degrees;
• wherein the camera and the mirror reflective element move together and in tandem with the mirror head when, with the interior rearview mirror assembly mounted at the interior portion of the interior cabin of the vehicle, the mirror head is adjusted about the mounting structure to provide a rearward view for a driver of the vehicle viewing the mirror reflective element;
• an electronic control unit (ECU);
• wherein image data captured by the camera is transferred to the ECU;
• wherein the ECU comprises electronic circuitry and associated software, and wherein the electronic circuitry of the ECU comprises an image processor operable to process image data transferred to the ECU;
• and
• wherein, with the interior rearview mirror assembly mounted at the interior portion of the interior cabin of the vehicle, (i) image data captured by the camera and representative of the first region is processed at the ECU for monitoring at least the driver of the vehicle and (ii) image data captured by the camera and representative of the second region is processed at the ECU for monitoring at least a passenger region within the interior cabin of the vehicle.
