Patent ID: 8294694

Claim:
A three-dimensional image display device which irradiates illuminating light on a display device and displays a three-dimensional image on an image reconstruction display unit using illuminating light transmitted through the display device, comprising a control image optimizing unit, wherein the control image optimizing unit is configured to: apply a voltage to a position corresponding to each pixel of a control image on the display device; calculate a solution of the three-dimensional image based on a solution of the control image included in a calculation target region, and perform an evaluating process for evaluating whether or not the solution of three-dimensional image is an optimized solution; perform a solution changing process for changing the solution of the control image included in the calculation target region by a move operation; determine an optimized solution of three-dimensional image by repeating the evaluating process and the solution changing process; record a control image on the display device based on the solution of the control image corresponding to the optimized solution of the three-dimensional image; and exclude, from the calculation target region, a region of pixels where an amplitude of the illuminating light transmitted through the display device may not be linearly controlled due to the applied voltage at each pixel within the excluded region being with a range where the amplitude does not increase as the voltage increases.
