An image processing apparatus performs of: acquiring an image; calculating a feature amount of each pixel of an object in the image; extracting a change region including a background and the object based on difference information in pixels; identifying the image from a start to an end of the partial change in the background; determining whether the calculated feature amount is similar to the feature amount of background model information regarding a feature amount of each pixel constituting the background; when determining dissimilarity and when the pixel determined to be dissimilar is the pixel included in the change region of the image, determining that the pixel is the pixel that corresponds to the background having a change; registering the information of the feature amount of the pixel determined to be dissimilar onto the background model information; and extracting the object from the image using a background difference.
