1. An image processing device comprising:

  • decoding circuitry that generates an image by decoding an encoded stream encoded in units having a layer structure;

    filter determination circuitry that determines whether to apply a strong filter of the image processing device which is stronger than another filter of the image processing device by using a value obtained by multiplying a strength parameter representing strength of a deblocking filter for a block boundary by a determination parameter representing a threshold used in the determination of the deblocking filter, which is a boundary between a block of the image generated by the decoding circuitry and an adjacent block adjacent to the block; and

    filter circuitry that applies the strong filter for the block boundary if the filter determination circuitry has determined to apply the strong filter.
