Patent ID: 7843636

Claim:
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.
