There is provided with an image processing apparatus for measuring a flow of a measurement target based on a video. A detection line indicating a position at which the flow of the measurement target in the video is measured is set. From each of a plurality of images in the video, a plurality of partial images set in a vicinity of the detection line are extracted. The flow of the measurement target passing the detection line is measured using the partial images.
