Position indicator for 3D display

摘要

A device 120 for processing three-dimensional [3D] image data 122 for display on a 3D display 160, the 3D display being arranged for adjacently emitting, in a viewing cone 180, a series of views 100 of the 3D image data, the series of views enabling autostereoscopic viewing of the 3D image data at multiple viewing positions 182, 184 in the viewing cone by a viewer perceiving two different ones of the series of views, and the device comprising an indicator generator 140 arranged for establishing a graphical shape in the 3D image data for, when being displayed on the 3D display, providing to the viewer a position indicator graphically representing a relative position of the two different ones of the series of views within the series of views.

1. A device for processing three-dimensional (3D) image data for display on a 3D display, the 3D display being arranged for adjacently providing, in a viewing cone, a series of views of the 3D image data, the series of views enabling autostereoscopic viewing of the 3D image data at multiple viewing positions in the viewing cone by a viewer perceiving two different ones of the series of views, the device comprising:
an indicator generator arranged for placing a graphical shape in the 3D image data, wherein a display of the graphical shape on the 3D display provides to the viewer a position indicator graphically representing a relative position of the two different ones of the series of views within the series of views, wherein the graphical shape includes
a reference shape for graphically representing a reference position of a reference view within the series of views, anda position shape for graphically representing a current position of the two different ones of the series of views within the series of views,wherein the display of the graphical shape on the 3D display provides the viewer a reference part and a position part of the position indicator having a relative spatial alignment graphically representing the relative position of the two different ones of the series of views within the series of views, wherein the graphical shape can provide an indication of a pseudoscopic perception of the 3D image data, wherein the indication is an average of at least two of the graphical shapes in the series of views.
