1. An apparatus comprising:
a receiver circuit,
wherein the receiver circuit is arranged to receive an image representation of a scene,
wherein the image representation is provided with respect to a scene coordinate system,
wherein the scene coordinate system comprises a reference position;
a determiner circuit,
wherein the determiner circuit is arranged to determine viewer poses for a viewer,
wherein the viewer poses is provided with respect to a viewer coordinate system;
an aligner circuit, wherein the aligner circuit is arranged to align the scene coordinate system with the viewer coordinate system by aligning the scene reference position with a viewer reference position in the viewer coordinate system;
a renderer circuit, wherein the renderer circuit is arranged to render view images for different viewer poses in response to the image representation and the alignment of the scene coordinate system with the viewer coordinate system;
an offset processor circuit,
wherein the processor circuit is arranged to determine the viewer reference position in response to a first viewer pose,
wherein the first viewer post is a viewer pose for which alignment is performed,
wherein the viewer reference position is dependent on an orientation of the first viewer pose,
wherein the viewer reference position has an offset with respect to a viewer eye position for the first viewer pose,
wherein the offset comprises an offset component in a direction opposite to a view direction of the viewer eye position,
wherein the offset processor circuit is arranged to determine the offset in response to an offset indication,
wherein the receiver circuit is arranged to receive an image data signal,
wherein the image data signal comprises the image representation and the offset indication.
