A feature point extraction unit 901 extracts a feature point suitable for calculation of parallax from pixels constituting a region targeted for calculation of parallax and pixels located near the targeted region. A first parallax calculation unit 902 calculates parallax for the extracted feature point by performing a search for corresponding points. A second parallax calculation unit 903 calculates parallax for each of the pixels constituting the targeted region based on the parallax calculated by the first parallax calculation unit 902 for the extracted feature point. |
