Assignee: SONY GROUP CORPORATION
Field: Audio-visual technology (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. An image processing device comprising:
control circuitry that:
receives an input comprising a flip flag and a one-dimensional input signal array of residual data;
determines whether the flip flag is set to true or false;
upon determining that the flip flag is set to false, performs 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, performs 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.
