摘要
A camera apparatus installated on a vehicle includes an image sensor having a RGB Bayer array of pixel sensors and a beam-splitting optical filter disposed between the camera lens assembly and the Bayer array. An incident light beam from a source such as a distant vehicle tail lamp becomes split into a plurality of light beams which become focused on respectively separate pixel sensors. Since the color of the light source is detected based on a plurality of pixel sensors, erroneous detection due to light falling on only a single R, G or B pixel sensor is prevented.
