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 element with a color mosaic filter and a patterned polarizer in which a number of polarizer units, of which the polarization transmission planes define mutually different angles, are arranged adjacent to each other within each single color pixel; a color information processing section 102 for getting average color intensity information by averaging the intensities of the light rays that have been transmitted through the polarizer units within each said single color pixel; and a polarization information processing section 103 for approximating, as a sinusoidal function, a relation between the intensity of light rays that have been transmitted through the polarizer units within each said single color pixel and the angles of the polarization transmission planes of the polarizer units.
