  • Publication number: 20240223916
    Abstract: A rearview mirror assembly for a vehicle is provided, including: an electro-optic element having at least one transflective coating; at least one imager comprising an array of pixels and positioned behind the electro-optic element to capture an image through the transflective coating; a processor capable of determining correction data for each pixel as a function of a location of the pixel within the array of pixels; and correcting color values for each pixel of the image captured based on the correction data for that pixel to correct for radial color distortion caused by the transflective coating.

  • Publication number: 20240179383
    Abstract: A monitoring system that includes an imaging device. The imaging device includes a first exposure profile and a second exposure profile. An illumination source is configured to emit at least one of infrared (IR) or near infrared (NIR) illumination. A control system is configured to alternate between the first exposure profile and the second exposure profile in accordance with a first pattern. The first exposure profile corresponds to the emission of illumination from the illumination source and the second exposure profile corresponds to ambient lighting.

  • Publication number: 20210056335
    Abstract: A variable infra-red illumination system and corresponding method is disclosed. The system may comprise a distance detector, a controller, an infra-red illumination device, and an imager. The distance detector may be operable to detect a first distance. The first distance may be a distance from a subject to the distance detector. The controller may be operable to determine an illumination intensity based, at least in part, on the first distance. The determined illumination intensity may be equal to or less than a maximum safe infra-red illumination intensity. The infra-red illumination device may be operable to illuminate a subject with infra-red light at the determined illumination intensity. Further, the infra-red illumination device may be located at a second distance from the subject. The second distance may be approximately equal to the first distance. The imager may be operable to capture one or more infra-red images of the illuminated subject.
