1. An image processing device comprising:
circuitry configured to set an encoding mode of encoding of an image by
setting a transform type with a minimum encoding cost in a non-joint chrominance encoding mode as a transform type in a joint chrominance encoding mode, and
deriving an encoding cost in the joint chrominance encoding mode, wherein the circuitry is configured to
compare the minimum encoding cost of the non-joint chrominance encoding mode with the encoding cost of the joint chrominance encoding mode, and
select a mode with the minimum encoding cost.
