Abstract
A spatial Fourier transforming apparatus jointly Fourier transforms a plurality of input images to obtain a Joint Fourier transform image of the plurality of input images. The apparatus comprises: input means for inputting a plurality of input images; a mask member having a plurality of aperture edges for defining a plurality of apertures each for transmitting a part of a corresponding one of the plurality of input images, the plurality of aperture edges having low correlation; and Fourier transforming means for jointly Fourier transforming the parts of the plurality of input images having passed through the plurality of apertures and for obtaining a Joint Fourier Transform image of the plurality of input images.
