摘要

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.

1. A picture processing device comprising:
a processor; first filter circuitry executable by the processor to apply a first filter to an input picture to generate a first filter picture and filter coefficient information; an attribute information generator executable by the processor to generate a first attribute value for each respective pixel of the first filter picture to which the first filter was applied and for which the filter coefficient information meets a predetermined criteria, and generate a second attribute value for each respective pixel in the first filter picture to which the first filter was not applied or the filter coefficient information does not meet the predetermined criteria, wherein the first and second attribute values indicate whether or not to apply a second filter to said each respective pixel of the first filter picture generated by the first filter circuitry; and second filter circuitry executable by the processor to only apply the second filter to a target pixel of the first filter picture having the first attribute value to generate a second filter picture.
