PROBLEM TO BE SOLVED: To provide a technology for reducing linear noise in all spatial frequency bandwidths while reducing afterimage without being influenced by random noise or objects.SOLUTION: The information processing apparatus includes: a spatial filtering means for spatially filtering image data of the current frame in a bandwidth based on spatial frequency of the objects and a recursive filtering means that performs recursive filter by acquiring filtered image data having processed earlier than the current frame, from a memory, multiplying the image data by a coefficient &alpha (&alpha<1), adding it to the filtered image data of the current frame, and storing the resultant image data in a memory.COPYRIGHT: (C)2011,JPO&INPIT
