Patent US 7,634,153

This invention provides an image processing apparatus which can effectively remove conspicuous noise contained in image data, while suppressing deterioration of image information. Image data containing noise is input from an input terminal (100). Based on the output condition upon outputting image data after noise is removed, a parameter determination module (103) determines predetermined parameters used in a noise removal process. An example of the output condition is information associated with a resolution upon outputting image data. An individual noise removal module (104) removes noise contained in the image data using the parameters, and image data after the noise has been removed is output from an output terminal (105).
