(57) Abstract :
An image processing apparatus, which calculates weight values based on difference values between the pixel values of pixel
positions in an image data and the pixel values of pixels of a peripheral region, calculates expectation values of the pixel values of
the peripheral region on the basis of weight values calculated for the pixels in the peripheral region, and makes the expectation
values the calculation results of the pixel position, includes: a plurality of normalized weighting functions for calculating the
weight values; a unit that calculates the total sum of weight of all of pixels in the peripheral region, for the plurality of normalized
weighting functions; a unit that selects the normalized weighting functions on the basis of the total sum of the weight values; and a
unit that calculates expectation values of the pixel values in the peripheral region based on the selected normalized weighting
function.
