Abstract To calculate a feature quantity with high robustness.SOLUTION: An arithmetic logical unit 1b converts a first hue value for each pixel in an image 10 to a second hue value calculated by referring a standard hue value Hbase as a standard that is determined based on a distribution state of the first hue value in the image 10. Then, the arithmetic logical unit 1b calculates a difference of the second hue values among pixels included in image pairs 11a to 11d set in a feature area 11 in the image 10, and calculates a local feature quantity 12 of the feature area 11 having a bit corresponding to each of the image pairs 11a to 11d based on the difference.SELECTED DRAWING: Figure 1 【課題】ロバスト性の高い特徴量を算出する。【解決手段】演算部1bは、画像10の各画素についての第1の色相値を、画像10における第1の色相値の分布状態に基づいて決定される基準色相値Hbaseを基準として算出された第2の色相値に変換する。そして、演算部1bは、画像10内の特徴領域11に設定された画素ペア11a〜11dのそれぞれに含まれる画素間における第2の色相値の差分を算出し、差分に基づいて、画素ペア11a〜11dのそれぞれに対応するビットを有する、特徴領域11についての局所特徴量12を算出する。【選択図】図1
