Abstract: In a data processing system, when displaying a foveated image, a producer processing unit generates plural different resolution versions of the frame to be displayed. A display processor then generates a view orientation transformed output version of the frame to be displayed using data from the plural different resolution versions of the frame to be displayed generated by the producer processing unit based on data indicative of which resolution version of the frame is to be used for respective regions of the view orientation transformed output version of the frame to be displayed provided to the display processor.

Abstract: When displaying a frame that is to be transformed based on a predicted view orientation, the frame is transformed based on a predicted view orientation by, for each of plural different regions of the frame, determining a predicted view orientation transformation matrix to use to transform the region of the frame by interpolating between a first predicted view orientation matrix that corresponds to a transformation for a predicted view orientation for a first time during the display of the frame and a second predicted view orientation matrix that corresponds to a predicted view orientation for a second, later time during the display of the frame; and then using the interpolated predicted view orientation transformation matrix determined for the region of the frame to transform the region of the frame. In this way each different region of the frame is subjected to a different predicted view orientation transformation.
