    摘要: A vehicular interior rearview mirror assembly includes a mirror head having an interior mirror reflective element. The mirror reflective element has a mirror transflector that transmits near-IR light incident thereon, transmits visible light incident thereon and reflects visible light incident thereon. The mirror assembly includes a camera disposed within the mirror head and viewing through the mirror transflector. The camera includes an imaging sensor having a quantum efficiency (QE) of at least 15% for near-infrared (near-IR) light having a wavelength of 940 nm. The mirror assembly further includes first, second and third near-IR illumination sources disposed within the mirror head and operable to emit near-IR light that passes through the mirror transflector. The near-IR illumination sources are at respective angles relative to a planar front surface of the mirror reflective element and, when powered, illuminate respective in-cabin regions for a driver monitoring function or an occupant detection function.

    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.

    摘要: A method of deriving color response characteristics of an image acquisition device, the method including: collecting first training data sets; deriving a first-order color response characteristic of the image acquisition device by performing a matching operation of statistically matching a relationship between device coordinates and colorimetric coordinates of an image acquisition device using the first training data sets; collecting second training data sets corresponding to a spectrum of one or more edge regions of a color gamut of a color matching function representing a sensitivity of a human eye; and deriving a second-order color response characteristic of the image acquisition device by further performing the matching operation using the second training data sets.
