Summary:PROBLEM TO BE SOLVED: To provide a pixel based feature quantity extraction circuit which is capable of extracting an image feature quantity in real time synchronously with pixel data output from an image sensor without requiring a buffer with a large capacity.SOLUTION: A pixel based feature quantity extraction circuit (10) performs pipeline processing of successively starting feature quantity calculations for a plurality of cells while receiving pixel data serially outputted from an image sensor and of successively completing feature quantity calculations for respective cells at the time of the completion of reception of the last pixel data of the respective cells from the image sensor.SELECTED DRAWING: Figure 5 【課題】大容量のバッファを必要とせずイメージセンサからのピクセルデータ出力に同期してリアルタイムで画像特徴量を抽出することができるピクセルベース特徴量抽出回路を提供する。【解決手段】ピクセルベース特徴量抽出回路（１０）は、イメージセンサからシリアル出力されるピクセルデータを受信しながら複数のセルの特徴量計算を順次開始し、イメージセンサから各セルの最後のピクセルデータを受信し終えた時点で各セルの特徴量計算を順次完了するパイプライン処理を行う。【選択図】図５
