Claim:
1. An image processing apparatus which performs a predetermined process on a coded stream generated by coding an image, the image processing apparatus comprising: a variable-length decoding unit configured to sequentially output, in a first order, luma and chroma components that are color components for each of at least one coding unit, by performing a first process on the coded stream; a reordering unit configured to sequentially output, in a second order different from the first order, luma and chroma components that are color components for each of at least one transform unit different from each of the at least one coding unit, by reordering the luma and the chroma components that are the color components outputted in the first order from the variable-length decoding unit; and a second processing unit including at least one of an inverse quantization unit, an inverse frequency transformation unit, a variable-length coding unit, and a reconstruction unit, configured to perform a second process on the luma and the chroma components that are the color components outputted in the second order from the reordering unit, for each of the at least one transform unit, wherein in the first order, the luma and the chroma components included in each of the at least one transform unit are non-sequentially arranged in each of the at least one coding unit, in the second order, the luma and the chroma components included in each of the at least one transform unit are sequentially arranged, the reordering changes the non-sequentially arranged luma and chroma components of the first order into the sequentially arranged luma and chroma components of the second order, and a size of the luma and chroma components in the first order for each of the at least one coding unit is larger than a size of the luma and chroma components in the second order for each of the at least one transform unit different from each of the at least one coding unit.
