1. An encoder, comprising:
circuitry; and
memory, wherein
the circuitry encodes an image block using the memory, and
in encoding the image block, the circuitry:
obtains the image block from a coding tree unit (CTU);
obtains one or more first parameters related to a size of the image block;
determines whether the one or more first parameters and one or more thresholds satisfy one or more determined relationships;
encodes a second parameter when the one or more first parameters and the one or more thresholds are determined to satisfy the one or more determined relationships, the second parameter indicating that a plurality of partitions are determined within the image block, the plurality of partitions including a non-rectangular partition; and
encodes the plurality of partitions after determining the plurality of partitions within the image block when the second parameter indicates that the plurality of partitions are determined within the image block, wherein
the one or more thresholds comprise one threshold; and
the one or more determined relationships are that each of the one or more first parameters is greater than or equal to the one threshold.
