Abstract:
A method and method and apparatus for data re-arrangement includes the steps of receiving output pixel coordinates (X, Y) and obtaining an input pixel offset value (ΔS, ΔT), wherein the output pixel coordinate represents a location for a two dimensional matrix. The input pixel offset value is obtained in reference to initial input pixel coordinates (S, T) which may be received with the output pixel coordinates or calculated based on the input and/or output pixel coordinates. The input pixel offset value may be any type of representation that provides for a delta value, for example, (ΔS, ΔT) may represent a shift representation for the offset within a matrix array. The method and apparatus for data re-arrangement further includes retrieving an input pixel based on the initial input pixel coordinates and the offset value.
