Abstract
An image processing apparatus according to the present invention includes: a color and polarization obtaining section 101 including a single-chip color image capture device that has a color mosaic filter 201 and a patterned polarizer 202 in which a number of polarizer units, having polarization transmission planes defining mutually different angles, are provided for multiple pixels of the same color (G) in the color mosaic filter 201; a polarization information processing section 103 for approximating, as a sinusoidal function, a relation between the intensities of light rays that have been transmitted through the polarizer units for the G pixels and the angles of the polarization transmission planes of the polarizer units; and a color mosaic interpolation section 103 for generating a color intensity image by performing color intensity interpolation and getting a color intensity that cannot be obtained at a pixel of interest.
