PROBLEM TO BE SOLVED: To provide a moving image processing device capable of reducing a calculation load in calculation of an optical flow using a moving image imaged by an on-vehicle camera.SOLUTION: A moving image processing device 10 comprises: a sight line information acquisition part 16 for acquiring sight line information which is information related to a sight line of a driver; a recognition range setting part 19 for setting a recognition range in which a sight line obtained based on the acquired sight line information is a center thereof, in an image contained in the moving image; a recognition degree setting part 15 for setting a recognition degree of an object included in the set recognition range to become larger than a recognition degree of an object not included in the recognition range; a corresponding position determination part 21 for making an attention position a corresponding position of a reference position when a difference between the attention position of an image for movement detection and the reference position of a reference image is equal to or less than the threshold; a detection accuracy determination part 20 for making a threshold to an object having a large recognition degree larger than a threshold to an object having a small recognition degree; and a movement detection part 22 for detecting an optical flow.SELECTED DRAWING: Figure 1
【課題】車載カメラで撮像された動画像を用いたオプティカルフローの演算において、演算負荷を軽減することのできる動画像処理装置を提供する。【解決手段】動画像処理装置10は、運転者の視線の情報である視線情報を取得する視線情報取得部16と、取得された視線情報に基づき得られる視線を中心とする認識範囲を動画像に含まれる画像内に設定する認識範囲設定部19と、設定された認識範囲に含まれる物体の認識度合を、認識範囲に含まれない物体の認識度合よりも大きく設定する認識度合設定部15と、動き検出用の画像の注目位置と参照画像の参照位置との差分が閾値以下である場合に注目位置を参照位置の対応位置とする対応位置決定部21と、認識度合が大きい物体に対する閾値を認識度合が小さい物体に対する閾値よりも大きくする検出精度決定部20と、オプティカルフローを検出する動き検出部22とを備える。【選択図】図1
