It is an object of the present invention to provide a technique for eliminating the unnaturalness in a generated moving image while achieving high speed processing in an image processing apparatus comprising a deblocking filter. A transcoder (1) comprises an MPEG2 decoder (2), a strength evaluation circuit (3), and an H.264 encoder (4). The strength evaluation circuit (3) calculates a filter strength parameter (104) on the basis of an image feature value parameter (103) acquired by the MPEG2 decoder (2). The H.264 encoder (4) applies a deblocking filter to an input image on the basis of the filter strength parameter (104) in a coding process. The H.264 encoder (4) codes a picture while the strength evaluation circuit (3) performs a filter strength calculation process on a subsequent picture concurrently. |
