1. An image processing apparatus comprising:
one or more memories storing instructions; and
one or more processors executing the instructions to:
extract a foreground image corresponding to an object included in a processing image using a background image corresponding to the processing image;
generate the background image from the processing image;
determine whether it is allowed to update the background image for use in the extraction; and
based on a result of the determination, update the background image for use in the extraction using the generated background image,
wherein in the determination, it is determined that (i) an update of the background image for use in the extraction is not allowed in a case where a proportion of the foreground image to the processing image is larger than a predetermined threshold and that (ii) the update of the background image for use in the extraction is allowed in a case where the proportion of the foreground image to the processing image is smaller than the predetermined threshold.
