1. An image processing apparatus comprising:
one or more processors; and
at least one memory, the at least one memory being coupled to the one or more processors and having stored thereon instructions executable by the one or more processors, wherein at least one of the one or more processors or execution of the instructions cause the image processing apparatus to function as:
a vector acquisition unit configured to acquire a plurality of motion vectors based on consecutive images;
a selection unit configured to select a motion vector of interest and a plurality of neighboring motion vectors neighboring the motion vector of interest from the acquired plurality of motion vectors;
a similarity acquisition unit configured to acquire a degree of similarity between two motion vectors; and
a reliability acquisition unit configured to acquire a degree of reliability represented by a value related to a total number of neighboring motion vectors having high degrees of similarity to the motion vector of interest,
wherein the similarity acquisition unit calculates, as the degree of similarity of motion, a norm of a difference between two motion vectors.
