1. An image processing apparatus comprising:
a moving image acquisition unit configured to acquire a first moving image and a second moving image that have been obtained by capturing a target object from positions different from each other using an imaging apparatus;
a generation unit configured to generate a first combined image by combining a first reference image obtained from the first moving image and a second reference image obtained from the second moving image, and generate a second combined image by combining a first comparison image obtained from the first moving image and a second comparison image obtained from the second moving image; and
a degree-of-slippage calculation unit configured to calculate a degree of slippage of the target object, based on deformation information estimated from the first combined image and the second combined image.
