ABSTRACT:
An apparatus including an image sensor is disclosed. The apparatus includes a polarization filter, an image sensor, and a processor connected to the image sensor. The polarization filter is adapted to filter out light polarized in a first direction from a first scene. The image sensor is adapted to capture the filtered light, and the image sensor includes support circuits to convert the captured filtered light to image data. The processor is adapted to process the image data to detect features of the first scene. The polarization filter filters out noise component of the image, thus increasing contrast. In another embodiment, a mosaic polarization filter is used to capture a scene in a first image including light from the scene having first polarity and to capture the scene in a second image including light from the scene having first polarity. The two images can be analyzed to determine various characteristics of the scene.
