Abstract
A first edge strength calculation circuit calculates an edge strength of each pixel in the image on the basis of results of detection by the first edge detection circuit. A filter strength setting unit sets a filter strength of a two-dimensional lowpass filter for each pixel, on the basis of the edge strength calculated by the edge strength calculation circuit. A second edge strength calculation circuit calculates an edge strength of each pixel in the image, on the basis of results of detection by the second edge detection circuit. An enhancement strength setting circuit sets an edge enhancement strength of the edge enhancement filter for each pixel, on the basis of the edge strength calculate by the second edge strength calculation circuit.
