Abstract
An encoder includes circuitry and memory connected to the circuitry. In operation, the circuitry: derives a correction parameter using only a neighboring reconstructed image that neighbors a processing unit which has a determined size and is located at an upper left of a current block to be processed in an image, among neighboring reconstructed images that neighbor the current block, and performs correction processing of the current block based on the correction parameter derived, when the current block has a size larger than the determined size.

An encoder, comprising:
- circuitry;
- and
- memory connected to the circuitry,
- wherein, in operation, the circuitry:
- derives a correction parameter using only a neighboring reconstructed image that neighbors a processing unit which has a determined size and is located at an upper left of a current block to be processed in an image, among neighboring reconstructed images that neighbor the current block, and performs correction processing of the current block based on the correction parameter derived, when the current block has a size larger than the determined size.
A decoder, comprising:
- circuitry;
- and
- memory connected to the circuitry,
- wherein, in operation, the circuitry:
- derives a correction parameter using only a neighboring reconstructed image that neighbors a processing unit which has a determined size and is located at an upper left of a current block to be processed in an image, among neighboring reconstructed images that neighbor the current block, and performs correction processing of the current block based on the correction parameter derived, when the current block has a size larger than the determined size.
