Device and method for adjusting parallax, imaging apparatus, and image reproduction device

摘要

A distance determining section increases a convergence point distance by a distance proportionate to an operation of an up key. The distance determining section reduces the convergence point distance by a distance proportionate to an operation of a down key. A target convergence point distance is incremented by 1 m per pressing operation of the up key. The target convergence point distance is decremented by 1 m per pressing operation of the down key. A shift amount setting section converts the target convergence point distance into a shift amount that corresponds to the target convergence point distance. The shift amount is set to an image shifting section. The image shifting section shifts each cut out region by the shift amount from a reference position and cuts out viewpoint images with the cut out regions from original left and right viewpoint images. Thus, the parallax-adjusted viewpoint images are produced.

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.
