摘要： An image processing apparatus includes a light source configured to emit light onto a glass; an image-capturing unit configured to capture light from an image-capturing region including reflection light of the emitted light from the glass; an object detection filter used to detect an object attached to the glass, light from a portion of the image-capturing region entering the object detection filter; an exposure control unit configured to determine a first exposure amount used in image capturing for a first region where the object detection filter does not exist and a second exposure amount used in image capturing for a second region where the object detection filter exists; and an image analysis unit configured to analyze a captured image obtained by the image-capturing unit. The image-capturing unit switches an exposure amount used in an image-capturing process for the image-capturing region between the first exposure amount and the second exposure amount.

摘要： An imaging device includes an optical filter. The optical filter has a configuration in which a polarization filter layer and a spectral filter layer are laminated in light transmission direction. Of the polarization filter layer and the spectral filter layer, the layer on the lower side in lamination direction has an uneven top face in the lamination direction. The optical filter is formed by filling the uneven top face with a predetermined filling material so as to even out the top face and then forming other layer.
