Abstract
A range-finding system includes two imaging devices to capture multiple images from two different viewpoints and a parallax calculator to calculate parallax based on the multiple images captured by the two imaging devices. The parallax calculator includes an estimation unit to estimate a correction value based on the amount of image deviation in a lateral direction corresponding to pixel position in the images captured by the two imaging devices and a correction unit to correct a pre-correction parallax or an image based on the correction value estimated by the estimation unit.
