A device that includes at least one memory unit adapted to store image data; the device is characterized by including a configurable filter adapted to apply de-ringing filtering and de-blocking filtering such as to filter image data retrieved from the at least one memory unit, whereas the device is adapted to repetitively determine a configuration of the configurable filter in response to received image data and to at least one mode selection rule and to configure the configurable filter in response to the determination. A method for filtering image data, the method includes receiving or defining filtering mode selection rules; and receiving image data; whereas the method is characterized by including repeating the stages of: determining a configuration of a configurable filter that is adapted to perform de-ringing and de-blocking filtering, in response to the received image data and to at least one mode selection rule; configuring the configurable filter in response to the determination; and filtering, by the configurable filter, image data.
