STEREOSCOPIC VIDEO DISPLAY DEVICE, MANUFACTURING METHOD THEREOF, AND POSITIONAL DISPLACEMENT ADJUSTING DEVICE THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a positional displacement adjusting device capable of accurately adjusting positions of a film and a lens array while taking elongation/contraction of the film into account.SOLUTION: A positional displacement adjusting device 100 includes: an imaging apparatus 110 for imaging a film 20 and a lens array 30 in which a line pattern for adjustment is overlapped on a plurality of element images; enlargement discrimination means 121 for discriminating whether the line pattern for adjustment is enlarged in an element lens included in a captured image; imaging position control means 123 by which, in the case where the line pattern for adjustment is not enlarged, the imaging apparatus 110 and the enlargement discrimination means 121 are made execute processing again; positional displacement calculation means 125 by which, in the case where the line pattern for adjustment is enlarged, a positional displacement direction and a positional displacement amount between the film 20 and the lens array 30 are calculated; and positional displacement adjusting means 127 for moving the film 20 on the basis of the positional displacement direction and the positional displacement amount.SELECTED DRAWING: Figure 3
