Image display method for a stereoscopic image

1. An image display method wherein an image display apparatus which includes a light source and an optical system is used,

said optical system including:

(A) an optical modulation section having a plurality of pixels and configured to modulate light from said light source by means of said pixels to produce a two-dimensional image and emit spatial frequencies of the produced two-dimensional image along a plurality of diffraction angles corresponding to different diffraction orders produced from each of said pixels;

(B) a Fourier transform image forming section configured to Fourier transform the spatial frequencies of the two-dimensional image emitted from said optical modulation section to produce a number of Fourier transform images corresponding to the number of diffraction orders;

(C) a Fourier transform image selection section configured to select a Fourier transform image corresponding to a desired diffraction order from among the Fourier transform images produced corresponding to the diffraction orders; and

(D) a conjugate image forming section configured to form a conjugate image of the Fourier transform image selected by said Fourier transform image selection section; and

said image forming method comprising:

determining a fixed relationship for correcting two-dimensional image data based at least on controlling an opening or closing of apertures of a spatial filter to spatially and temporally filter Fourier transform images of the Fourier transform image selection section;

correcting two-dimensional image data based on the fixed relationship; and

a step, carried out by said optical modulation section, of producing a two-dimensional image based on two-dimensional image data whose aberrations caused by said optical system are corrected.
