Claim One:
1. A disparity calculating device configured to calculate disparity serving as image shift between images obtained from two viewpoints, comprising: image dividing circuitry configured to divide each of the images into multiple regions; correction amount determining circuitry configured to calculate an image shift amount between the images in a direction perpendicular to a direction where two viewpoints are connected for each of the regions resulting from division by the image dividing circuitry, and to determine a correction amount corresponding to the image shift amount; disparity calculating circuitry configured to correct the images for each of the regions on the basis of the correction amount determined by the correction amount determining circuitry, and to calculate disparity on the basis of the corrected images; and correction instructing circuitry configured to instruct the correction amount determining circuitry to determine a correction amount each time the correction instructing circuitry obtains a predetermined number of frames, wherein, in a case where directions of image shift for the individual regions are the same, the disparity calculating circuitry is configured to select a minimum value from among image shift amounts calculated for the individual regions, and to correct the images for each region after correcting the entire images in accordance with the minimum value.
