Classification: CPC H | IPC H

Claim 12:
13. An image processing method performed by an image processing device, the method comprising:
receiving an input comprising a flip flag and a one-dimensional input signal array of residual data;
determining whether the flip flag is set to true or false;
upon determining that the flip flag is set to false, performing a first operation comprising:
enabling a forward data path for performing a matrix operation of a one-dimensional orthogonal transform on the one-dimensional input signal array,
disabling a reverse data path for performing the matrix operation of the one-dimensional orthogonal transform on the one-dimensional input signal array, and
performing the matrix operation of the one-dimensional orthogonal transform on the one-dimensional input signal array in accordance with the forward data path, and

upon determining that the flip flag is set to true, performing a second operation comprising:
disabling the forward data path,
enabling the reverse data path, and
performing the matrix operation of the one-dimensional orthogonal transform on the one-dimensional input signal array in accordance with the reverse data path.
