PCT No. PCT/FR94/00472 Sec. 371 Date Jan. 11, 1996 Sec. 102(e) Date Jan. 11, 1996 PCT Filed Apr. 26, 1994 PCT Pub. No. WO94/26071 PCT Pub. Date Nov. 10, 1994The invention relates to a single-camera autostereoscopic picture-taking device implementing an array of cylindrical lenses, characterized in that it comprises in succession: a single inlet objective (L1, L2); said lens array (20), which has a focal length such that for an image area equal to the pitch (p) of the lenses making it up, the image of the entrance pupil of the telecentric objective (L1, L2) has a nominal width equal to said pitch; a transfer optical system (L3, L4) having magnification of less than unity; and an image sensor (22), the transfer optical system (L3, L4) directing the light rays that emerge from the lens array (20) onto the image sensor (22), the image (21) of the lens array (20) in the transfer optical system (L3, L4) being such that the pitch (p) of the lenses of the lens array (20) corresponds therein to an integer number of image points (pixels) of the image sensor (22).
