Abstract
A video processing method includes dividing a processing target image, which forms a video image, into a plurality of divided areas; determining a bandwidth applied to the divided areas; computing a filter coefficient array for implementing frequency characteristics corresponding to a band limitation using the bandwidth; subjecting the image data to a filtering process using the filter coefficient array; deriving a value of error information between the obtained data and the original image data, and computing an allocation coefficient used for determining an optimum bandwidth, based on the derived value; determining, for each divided area, the optimum bandwidth corresponding to the allocation coefficient, and computing an optimum filter coefficient array for implementing the frequency characteristics corresponding to a band limitation using the optimum bandwidth; subjecting the image data of the divided area to a filtering process using the optimum filter coefficient array; and synthesizing the obtained data of each divided area.
