An optical system comprises an optically transmissive substrate comprising a metasurface which comprises a grating comprising a plurality of unit cells. Each unit cell comprises a laterally-elongated first nanobeam having a first width; and a laterally-elongated second nanobeam spaced apart from the first nanobeam by a gap, the second nanobeam having a second width larger than the first width. A pitch of the unit cells is 10 nm to 1 μm. The heights of the first and the second nanobeams are: 10 nm to 450 nm where a refractive index of the substrate is more than 3.3; and 10 nm to 1 μm where the refractive index is 3.3 or less.

An image processing system according to the present embodiment includes a generating unit and a display controlling unit. The generating unit generates a group of different types of parallax image sets that are to three-dimensionally display an object onto the display surface of the displaying unit, from different types of three-dimensional medical image data generated by performing different types of image processing onto imaging data of the object collected by a medical image diagnosis apparatus. The display controlling unit performs control so that display conditions of the group of different types of parallax image sets are switched in accordance with the switching of the viewpoint position around the object displayed on the display surface and that the group of different types of parallax image sets are superimposed and displayed.

A method and an apparatus for generating a pair of images consisting of a dominant image to be displayed to a dominant eye and a nondominant image to be displayed to a nondominant eye causes a user to perceive a three-dimensioned image. The apparatus is configured to perform the method initiated by receiving the dominant image in a dominant image buffer. A skewing engine performs a skewing transformation; a rotating engine performs a rotating transformation; and a translating engine performs a translating and scaling transformation thereby to produce the nondominant image for storage in the nondominant image buffer.
