Abstract
A contour direction estimating unit estimates a contour direction in which signal values of pixels are constant values for each pixel, a low pass filter unit smooths a signal value of the pixel based on a signal value of each reference pixel that is a pixel of a reference region corresponding to the pixel and arranged in the contour direction of the pixel estimated by the contour direction estimating unit for each pixel, and a high frequency expanding unit generates a high frequency component of the signal value of the pixel and expands a frequency band for the signal value of the pixel.
