Abstract
An image processing device that enables improvement in processing efficiency in encoding or decoding includes a type E0 of an LCU and its coefficient are determined on the encoder side. The coefficient of the type E0 was sent to the decoder side at the time of the LCU, and has been stored in an EO buffer included in an adaptive offset filter on the decoder side. For the LCU, therefore, a copy of the coefficient of the type E0 in the EO buffer is used on decoder side without the sending of the coefficient of the type EO. The parameters of the adaptive offset filter are sent sequentially at the beginning of an LCU for each LCU rather than in one batch at the beginning of the frame.
