Document Type and Number:
Japanese Patent JP6624462
Kind Code:
B2
Abstract:
The present disclosure relates to an image processing device and method that enable improvement in processing efficiency in encoding or decoding.A type E0 of an LCU 115 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 111, and has been stored in an EO buffer included in an adaptive offset filter on the decoder side. For the LCU 115, 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 E0. As described above, the parameters of the adaptive offset filter, which are transmitted in one batch at the beginning of a frame in the related art, are sent sequentially at the beginning of an LCU for each LCU. The present disclosure can be applied to, for example, an image processing device.
