Patent ID: 8531454

Claim:
A display apparatus comprising: a display unit including pixels arranged in a matrix form in a display region; an optical plate opposed to the display unit and including exit pupils arranged in a first direction with a specific pitch, the optical plate controlling light rays entered in each of the exit pupils from the display unit to emit in different directions, the display apparatus generating a stereoscopic image by displaying an elemental image that multiple viewpoint image corresponding to viewpoints are rearranged in a region defined by the specific pitch in the display region; an estimation unit configured to estimate a viewing position of a viewer; and a coordinate determination unit configured to determine coordinates of virtual cameras each having a different viewpoint in a CG space, the coordinate determination unit configured to determine a center position of the coordinates of virtual cameras in the CG space by projecting the viewing position to the CG space, to project a first light ray emitted from the optical plate to the CG space based on the specific pitch and an emitting direction of the first light ray, and to make intervals between the virtual cameras shorter than an interval along the first direction of a part of the first light ray, the part of the first light ray having a viewpoint image on the same view point and being observed at the center position; a selection unit configured to make a selection as to which image in images shot by which the virtual cameras should be displayed on which pixels in the display region; and a generation unit configured to dispose the virtual cameras on the coordinates of the virtual cameras in the CG space, shoot a drawing object in the CG space, and generate an elemental image to rearrange multiple viewpoint image of the drawing object based on the selection result in the selection unit.
