AUTOSTEREOSCOPIC IMAGE OUTPUT DEVICE Russian patent published in 2013 - IPC H04N13/00 

FIELD: physics.

SUBSTANCE: autostereoscopic image output device has an image panel having an array of image pixels defining an image, the image pixels being arranged in rows and columns. An array of parallel lenticular elements is positioned over the image panel, the lenticular elements having optical focal axes that are slanted at an angle (ϕ) to the image pixel columns. The image output device is operable in first and second modes, with the image panel and lenticular element array rotated by 90 degrees between the modes, thereby providing a horizontal mode of operation and a vertical mode of operation, the slant angle (ϕ) in the horizontal mode satisfies: 1 ≥ tanϕ ≥ 1/2.

EFFECT: enabling a 3D image device to be used in both the horizontal and the vertical mode, while maintaining a good view-distribution and image pixel structure.
