Abstract:
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.

Claim (Index 7):
An image decoding method, comprising:\n decoding a bit stream to generate decoded image data; decoding a first control information indicating whether or not a filtering process is performed on an image block of image blocks of the decoded image data; decoding a second control information indicating whether or not the filtering process is performed across a boundary of a current slice including the image block; deriving a position of the image block, the position of the image block being obtained from block size information for the image block; when the first control information indicates the filtering process is not performed on the image block, not performing the filtering process on any pixel of the image block; and when the first control information indicates the filtering process is performed on the image block, performing the filtering process on the image block based on the first control information, the second control information, and the position of the current image block.
