Abstract
There are provided an image processing apparatus, an image processing method, a program, and a recording medium capable of compatibly achieving a high-accuracy filtering process and reduction in a necessary storage capacity. An image processing apparatus includes a filtering process unit that performs an image filtering process including a plurality of filtering processes. The filtering process unit applies a filter to processing target data to acquire filter application process data, and 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” specified based on an optical characteristic of an optical system used when the original image data is acquired, that is, the optical characteristic according to an imaging condition when the original image data is acquired.
