1. A decoder that decodes an image, the decoder comprising:
circuitry; and
memory coupled to the circuitry, wherein
in operation, the circuitry:
splits a current picture to be decoded into two or more tiles; and
decodes the current picture by performing the decoding on a slice, the slice being rectangular-shaped, the slice being made up of one or more tiles or a part of a tile obtained by the splitting,
in the decoding of the current picture, the circuitry derives first information on a region in a predetermined manner without retrieving the first information from header information, the region being occupied by a slice located at a lower-right corner of the current picture, and
the first information is not included in the header information.
