IMAGE PROCESSING DEVICE, FILTER ACQUISITION DEVICE, IMAGE PROCESSING METHOD, FILTER ACQUISITION METHOD, PROGRAM, AND RECORDING MEDIUM

摘要

Provided are an image processing device capable of balancing highly accurate filtering processing and required storage space reduction, an image processing method, and a program. In addition, further provided are: a filter acquisition device capable of acquiring a filter favorable for use in such filtering processing; a filter acquisition method; a program; and a recording medium. An image processing device 35 is equipped with a filtering processing unit 41 for performing image filter processing including multiple instances of filtering processing. During each instance of filtering processing, the filtering processing unit 41 obtains filter application processing data by applying a filter to data to be processed, and obtains gain application processing data by applying a gain to the filter application processing data. The gain to be applied to the filter application processing data during each instance of filtering processing is obtained on the basis of frequency properties targeted by the image filter processing.
