摘要：An image processing apparatus (102) conducts an image processing to detect

an object, existing in a lighting area irradiated by a lighting unit (202), based on an imagecaptured by an image capturing unit (101). The image processing apparatus (102) includesa memory (209) to store first pixel value information \"y(x,t),\" for each one of a plurality ofsections \"x\" obtainable by dividing the captured image, and correlation value information\"z(x)\" for the first pixel value information \"y(x,t)\" and an external disturbance factor forcomputing an external disturbance factor value \"S\" indicating a level of the externaldisturbance factor for each one of the plurality of sections \"x,\" the pixel value information\"y(x,t)\" variable along the time \"t;\" and a process execution unit (1021) to compute theexternal disturbance factor value \"S\" by multiplying the first pixel value information\"y(x,t)\" and the correlation value information \"z(x)\" for each one of the plurality ofsections \"x,\" to compute a fluctuation component \"S x z(x)\" caused by the externaldisturbance by multiplying the computed external disturbance factor value \"S\" and thecorrelation value information \"z(x),\" to compute second pixel value information \"y'(x,t)\" byremoving the fluctuation component \"S x z(x)\" from the first pixel value information\"y(x,t),\" and to conduct the image processing using the second pixel value information\"y'(x,t)\" having removed the fluctuation component \"S x z(x).
