With regard to objects such as pictures, geometric figures, and symbols shown in the image to be processed by an image processing apparatus, in order to select an object that does not overlap in position with a user-indicated position, an image processing apparatus 100 acquires a user-indicated position in an image 200 in which an object 201 is shown, generates partition regions 209 that partition the target region of the image 200, on the basis of the position of the object 201, identifies a partition region 211 on the basis of a user-indicated position, and determines whether the object 201 has been selected, on the basis of the identified partition region 211.
