Abstract
To independently set correction information relating to edge enhancement processing and noise reduction processing for each of three or more spatial frequency bands.SOLUTION: An image processing device includes: a setting unit that includes a contour component of a first spatial frequency band and a second spatial frequency lower than a first spatial frequency within the first spatial frequency band, includes a contour component of the second spatial frequency band that partially overlaps with the first spatial frequency band and a third spatial frequency lower than the second spatial frequency, and can independently set each correction information for each contour component of the third spatial frequency band partially overlapping with the second spatial frequency band, and sets each correction information on the basis of the display magnification of an image to be displayed; and a correction unit that corrects image data on the basis of each correction information set by the setting unit.SELECTED DRAWING: Figure 1
