A computer-assisted holographic-display apparatus comprises a diffraction image generator which receives an input image signal representing an object and computes corresponding diffraction pattern with a first sampling density. An interpolation processor is connected to the diffraction image generator via an intermediate page memory. The interpolation processor subjects the diffraction pattern to the interpolation process to create an interpolated diffraction pattern with an increased second sampling density. An interference pattern generator is connected to the interpolation processor to compute an interference caused pattern between the interpolated diffraction pattern and a reference wave by converting amplitude and phase distributions of the input image signal into the intensity distribution. The interference pattern is displayed on a previously selected displaying device.

A computer-assisted holographic-display apparatus comprising: first computation means for receiving an input image signal representing an object and for computing corresponding diffraction pattern data with a first sampling density; second computation means coupled to said first computation means, for interpolating the diffraction pattern data to generate interpolated diffraction pattern data with an increased second sampling density; and modulated light forming means connected to said second computation means, for forming a holographic image of the object by use of the interpolated diffraction pattern data.
