Abstract
An image input/output apparatus which can reproduce an image having a large focal depth, without decreasing the resolution and luminance. The apparatus has a wide range of practical applications, and can be, easily, quickly and exactly put to practical use. The apparatus includes a mechanism for inputting a plurality of images focused on different object planes, circuitry for Fourier-transforming the images input by the inputting mechanism circuitry for weighting and adding the images Fourier-transformed by the Fourier-transforming circuitry, and circuitry for performing an inverse Fourier transform of Fourier spectrum images obtained by the weighting and adding circuitry.
