Patent ID: 8873879

Claim:
An illusion image generating apparatus that includes at least a storing unit and a control unit, wherein the storing unit includes a filter storing unit that stores a wavelet frame with orientation selectivity or a filterbank with orientation selectivity that is a set of an approximate filter with no orientation and a plurality of detail filters with respective orientations, and an image data storing unit that stores image data, the control unit includes a decomposing unit that obtains subband signals by performing a multiresolution decomposition by the wavelet frame with orientation selectivity or the filterbank with orientation selectivity on the image data, and a reconstructing unit that obtains reconstructed image data by reconstructing an image by summing the subband signals obtained by the decomposing unit, and the reconstructing unit generates the reconstructed image data that creates a floating illusion by attenuating or amplifying a subband signal corresponding to at least one of detail filters with a predetermined orientation relative to a floating direction, in which an image is desired to be floated due to an illusion, among the detail filters, and wherein the reconstructed image is an illusion image that creates an illusion of floating due to the movement of the image or the viewer, and appears to move differently from the actual movement accompanied by the movement of the viewer or the movement of the image.
