To reduce processing time for estimating the position of an imaging target.SOLUTION: An image processing circuit disclosed herein is configured to image an imaging target to acquire an image of the imaging target, detect brightness of each unit area of the acquired image, compute a difference in detected brightness between two adjacent unit areas, and determine the position of the imaging target corresponding to pixels with brightness exceeding a given value in the image on the basis of the computed brightness difference.SELECTED DRAWING: Figure 2

    【課題】撮像対象の位置の推定する際、その処理時間を短縮させる。【解決手段】画像処理回路は、撮像対象を撮像して当該撮像対象の画像を取得し、取得された画像において単位領域ごとに輝度を検出し、検出された、隣り合う二つの単位領域間の輝度の差を演算し、演算された輝度の差に基づいて、画像において所定値を超える輝度を有する画素に対応する撮像対象の位置を決定する。【選択図】図2
