`
`(Currently Amended) An image encoder comprising:
`
`a splitter which, in operation, receives and splits an original picture into blocks;

`a first adder which, in operation, receives the blocks from the splitter and
`
`predictions from a prediction controller, and subtracts each prediction from its corresponding
`
`block to output a residual;

`
`from the adder to output transform coefficients;
