Abstract
A deblocking filter device according to a first feature includes: a deblocking filter configured to perform a filter process on a boundary between a first reconstructed block and a second reconstructed block adjacent to the first reconstructed block; and a filter controller configured to control boundary filtering strength of the deblocking filter based on whether or not at least one of the first reconstructed block and the second reconstructed block is encoded using JCCR (Joint coding of chroma residual) in which one joint prediction residual is generated from prediction residuals of a Cb chrominance component and a Cr chrominance component.
