Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an upsampling device and downsampling device, improving processing efficiency while maintaining high accuracy by effectively utilizing a layered structure of layout data.SOLUTION: An upsampling unit 44 is equipped with: a mesh adding section 441; and a new mesh data setting section 442. The mesh adding section 441 adds a new mesh to image data inputted from a spatial filter section 423. The new mesh data setting section 442 sets a value of zero to the image data on the added mesh and outputs the image data to an inverse Fourier transform section 424 together with the image data before the mesh addition.
