Provided are an image processing apparatus, an image processing method, an image processing program, and a recording medium for obtaining excellent noise removal effects. The image processing apparatus performs a process of removing noises from an input image. The image processing apparatus includes: a filter setting unit which sets a first filter coefficient and a second filter coefficient using a first target pixel value that a noise processing target pixel, a target to be processed has, and a reference pixel value that multiple reference pixels around the noise processing target pixel have; and a noise removing unit which produces a modified pixel value by summing luma components of the reference pixels with the first filter coefficient as the weights and summing chroma components of the reference pixels with the second filter coefficient as the weights, and removes noises from the noise processing target pixel using the modified pixel value. The input image comprises pixel values in ...
