Abstract:
1. A parallax adjustment device comprising: a first operation unit for outputting a first operation signal based on an amount of operating the first operation unit; a distance determining section for determining a target convergence point distance based on the first operation signal, the target convergence point distance being determined by increasing or reducing a current convergence point distance by a distance proportionate to the amount of operating the first operation unit, a convergence point distance being a distance to a convergence point at which no parallax is caused; a shift amount setting section for setting a shift amount of each viewpoint image such that an amount to be shifted per unit amount of operating the first operation unit is nonlinearly increased or reduced in a direction of parallax of the each viewpoint image in accordance with a distance change from the current convergence point distance to the target convergence point distance; and an image shifting section for shifting the each viewpoint image by the shift amount and thereby changing the parallax.
