摘要 |
<p>An image processing method includes determining a first bandwidth based on original image data; computing a filter coefficient array for implementing frequency characteristics corresponding to a band limitation using the first bandwidth; generating first filtered image data by subjecting the original image data to a filtering process using the first filter coefficient array; deriving an objective image-quality estimation value of the first filtered image data, and computing an allocation coefficient used for determining an optimum bandwidth, based on the objective image-quality estimation value; determining the optimum bandwidth corresponding to the computed allocation coefficient by referring to a table in which a correspondence relationship between the allocation coefficient and the optimum bandwidth is defined; computing an optimum filter coefficient array for implementing the frequency characteristics corresponding to a band limitation using the optimum bandwidth; and generating optimum filtered image data by subjecting the original image data to a filtering process using the optimum filter coefficient array.</p> |
