The present invention relates to an image processing device and method whereby deterioration of effects of filter processing due to local control of filter processing when encoding or decoding can be suppressed.
A boundary control flag generating unit of a control information generating unit generates boundary control flags based on system specification information which a system specification managing unit manages. A control unit of an adaptive filter processing unit determines a processing method for filter processing to be performed as to pixels nearby a slice boundary following the value of the boundary control flag. For example, selection is made to perform filter processing straddling slices or to perform filter processing closed at the present slice.
The present invention can be applied to an image processing device, for example.
