Title:
IMAGE REPRODUCER, SIGNAL PROCESSING DEVICE, AND IMAGE REPRODUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2018/225127
Kind Code:
A1
Abstract:
The present invention is provided with a layout setting unit (13a), (13b) that sets a memory layout for signals of a plurality of local regions divided by a data division unit (11a), (11b) in accordance with the processing direction of a Fourier transform processing or inverse Fourier transform processing, wherein: a Fourier transform unit (14a), (14b) performs a multi-dimensional Fourier transform on the signals of the plurality of local regions, the memory layout of which has been aligned with the processing direction of Fourier transform processing by the layout setting unit (13a), (13b); and an inverse Fourier transform unit (15a), (15b) performs a multi-dimensional inverse Fourier transform on the signals of the plurality of local regions, the memory layout of which has been aligned with the processing direction of inverse Fourier transform processing by the layout setting unit (13a), (13b).
