摘要： A vehicular interior rearview mirror assembly includes a mirror head accommodating an interior rearview mirror reflective element. The mirror reflective element has a mirror transflector that transmits near infrared light incident thereon, transmits visible light incident thereon and reflects visible light incident thereon. The mirror transflector includes repeating alternating layers of a higher refractive index layer and a lower refractive index layer. A megapixel camera is disposed within the mirror head behind the mirror reflective element and views through the mirror transflector. A near infrared illumination source is disposed within the mirror head and operable to emit near infrared light that passes through the mirror transflector. Responsive at least in part to the data processor processing captured image data, at least one selected from the group consisting of (i) driver attentiveness is monitored, (ii) driver drowsiness is monitored and (iii) driver gaze direction is monitored.

摘要： According to an aspect, there is provided an image sensing system comprising: at least two rolling shutter image sensors, each rolling shutter image sensor comprising an array of pixels in a frame arranged in a plurality of image lines extending along a width direction, and distributed in a scanning direction which is perpendicular to the width direction, wherein each rolling shutter image sensor is configured to scan its frame by sequentially scanning each image line along the scanning direction, wherein scanning each image line includes making the pixels in each image line sensitive to light for a predetermined exposure time, and then determining an intensity readout for each pixel of the respective image line; a controller configured to temporally stagger scanning of frames for each rolling shutter image sensor, such that the controller is configured to start scanning of frames from a first image line in the scanning direction, for each rolling shutter image sensor with a time delay with respect to the other rolling shutter image sensors; a lens system configured to project similar outgoing images of an object onto each rolling shutter image sensor, wherein the outgoing images are projected onto each rolling shutter image sensor such that each pixel of an outgoing image corresponding to a position on the object matches a pixel or group of pixels of another outgoing image corresponding to the respective position on the object, and such that the outgoing images are captured by each rolling shutter image sensor with differing colours of light, defined by different wavelengths; and a processor configured to identify matched pixels of different outgoing images corresponding to a respective position on the object, and to resolve the colour of the object based on the intensity readout of each matched pixel and the colours of light that the respective matched pixels were exposed to while they were sensitive.
