Abstract

Provided is an image processing device capable of performing appropriate noise removal or reduction on input images of various resolution. The image processing device includes a contour direction estimating unit () that estimates a contour direction in which a signal value is a constant value for each pixel, a low pass filter unit () that smoothes the signal value of the pixel based on the signal value of each reference pixel serving as a pixel of a reference region according to the pixel and arranged in the contour direction of the pixel estimated by the contour direction estimating unit for each pixel, and a parameter deciding unit () that decides intensity of smoothing by the low pass filter unit according to an enlargement factor obtained based on a ratio of resolution of an input image signal and resolution of an output image signal.
