Title OPTICAL ILLUSION IMAGE GENERATING DEVICE, MEDIUM, IMAGE DATA, OPTICAL ILLUSION IMAGE GENERATING METHOD, PRINT MEDIUM MANUFACTURING METHOD, AND PROGRAM
Abstract When carrying out multiple resolution decomposition on image data with a non-orientational approximation filter and either a orientationally selective wavelet frame or a orientationally selective filter bank, which is a set of a plurality of precision filters having respective orientationality, acquiring sub-band signals, and reconfiguring an image by summing the acquired sub-signals, the present invention generates reconfigured image data which generates a floating optical illusion by attenuating and amplifying a sub-band signal which corresponds to at least one precision filter from among the precision filters which has a prescribed orientationality for a float direction in which the image is to be made to float by way of optical illusion.
