Digital camera systems and methods are described that provide a color digital camera with direct luminance detection. The luminance signals are obtained directly from a broadband image sensor channel without interpolation of RGB data. The chrominance signals are obtained from one or more additional image sensor channels comprising red and/or blue color band detection capability. The red and blue signals are directly combined with the luminance image sensor channel signals. The digital camera generates and outputs an image in YCrCb color space by directly combining outputs of the broadband, red and blue sensors.

A vehicular exterior rearview mirror assembly includes a mirror casing, a mirror reflective element and a ground illumination module having a freeform optic, a ground illumination light source, and first, second and third icon light sources. With the vehicular exterior rearview mirror assembly mounted at the side of the vehicle and when the ground illumination light source is electrically powered to emit light, light emitted by the ground illumination light source that passes through the freeform optic illuminates the ground region adjacent to and along the side of the vehicle with a ground illumination intensity. When each individual icon light source is electrically powered to emit light, light emitted by the respective icon light source projects a respective projected image onto an icon region that is within the ground region. The respective projected images are individually projected to provide animated images projected onto the icon region.
