IMAGE PROCESSING DEVICE, METHOD, AND PROGRAM, DYNAMIC IMAGE ENCODING DEVICE, METHOD, AND PROGRAM, DYNAMIC IMAGE DECODING DEVICE, METHOD, AND PROGRAM, AND ENCODING/DECODING SYSTEM AND METHOD

In order to preserve edges of a picture and to suppress a residual distorted signal in a reproduced picture, a picture processing device (in-loop filter) includes a first filter unit for applying a first filter to an input picture to generate a first filter picture, an attribute information generator which generates an attribute value indicating whether or not to apply a second filter to each pixel of the generated first filter picture, and a second filter unit for applying the second filter to a target pixel of the first filter picture selected on the basis of the attribute value of each pixel of the generated first filter picture, to generate a second filter picture.
