An information processing apparatus (10) comprises: a spatial filtering means (41, 42) for performing spatial filtering in a frequency range based on a spatial frequency of an object for image data of a current frame and a recursive filtering means (45) for performing recursive filtering by obtaining image data, which has been processed prior to the current frame, from a memory, multiplying the obtained image data by a coefficient ± (± < 1), adding the image data multiplied by the coefficient ± to the image data of the current frame after the spatial filtering, and storing the image data after the addition in the memory.
