Abstract
There are provided an image processing apparatus, an image processing method, and a program capable of realizing a desired image filtering process specified based on an optical characteristic of an individual optical system with high accuracy using a simple computation process. Further, there are provided a filter acquisition apparatus, a filter acquisition method, program, and a recording medium capable of acquiring a filter which is suitably usable in an image filtering process. A filtering process unit 41 (image processing apparatus 35) applies a filter to processing target data to acquire filter application process data, applies a gain to the filter application process data to acquire gain application process data, in each filtering process. In each filtering process, the gain applied to the filter application process data is acquired based on a target frequency characteristic of the image filtering process.
