Abstract
An image processing device according to one embodiment of the invention includes a contour direction estimating unit, a direction evaluating unit, a reference region weighting processing unit, and a composition operation unit. The contour direction estimating unit estimates a contour direction in which signal values of pixels are constant values for each pixel, the direction evaluating unit decides an evaluation value of each reference pixel of the pixel based on the contour direction of the pixel estimated by the contour direction estimating unit and the contour direction of each reference pixel serving as a pixel in a reference region corresponding to the pixel for each pixel, the reference region weighting processing unit decides a weighting coefficient of the reference pixel based on the contour direction of the pixel estimated by the contour direction estimating unit and the direction of each reference pixel of the pixel from the pixel, and the composition operation unit smoothes a signal value of the pixel based on the evaluation value decided by the direction evaluating unit and the weighting coefficient decided by the reference region weighting processing unit using a signal value of the reference pixel of the pixel.
