1. An image coding device comprising:
a coding unit configured to code an image; and
a setting unit configured to set information indicating a level indicating a load of a decoding process of an entirety of the image, a size of a partial region of the image, and a level indicating a load of a decoding process of the partial region, for controlling decoding of coded data, which is transmitted from the image coding device to an image decoding device and in which the image is coded, the information indicating the size of the partial region of the image and the level indicating the load of the decoding process of the partial region both also being transmitted from the image coding device together with the coded data to the image decoding device,
wherein the partial region is an independently decodable region of the image that is less than the entirety of the image, and the setting unit is further configured to set the information indicating the level indicating the load of the decoding process of the entirety of the image and the level indicating the load of the decoding process of the partial region by setting a first level indicating the load of the decoding process of the entirety of the image and setting a second level indicating the load of the decoding process of the partial region, the first level being different than the second level, and
wherein the coding unit and the setting unit are each implemented via at least one processor.
