Original Abstract Submitted

A first discrete Fourier transform unit generates a first frequency spectrum by two-dimensional discrete Fourier transform of an input image signal. A second discrete Fourier transform unit generates a second frequency spectrum by two-dimensional discrete Fourier transform of an output image signal output from a high frequency emphasis circuit. A first and second high frequency component index generators generate a first and second high frequency component indices indicating a total amount of high frequency components based on the first and second frequency spectra, respectively. A high frequency component emphasis ratio calculator calculates a high frequency component emphasis ratio which is a ratio between a first high frequency component index and a second high frequency component index. An emphasis amount controller generates an emphasis amount control value based on a high frequency component emphasis ratio and a target emphasis ratio, and supplies it to the high frequency emphasis circuit.
