ABSTRACT:
A single camera autostereoscopic video device including an array of cylindrical lenses. The device includes a single inlet objective having a single optical axis. The lens array is positioned substantially in the image focal plane of the entrance objective and has a focal length such that for an image area equal to the pitch of the lenses constituting the array, the image of the entrance pupil of the inlet objective has a nominal width equal to the pitch. The device also includes a transfer optical system and an image sensor. The transfer optical system directs the light rays which emerge from the lens array onto the image sensor. The image of the lens array in the transfer optical system being such that the pitch of the lenses of the lens array corresponds therein to an integer number of image points (pixels) of the image sensor.
