Abstract
A disclosed image processing apparatus detects a motion vector between a first image and a second image based on the correlation between the first image and the second image. When the degree of reliability of the detected motion vector is determined based on an evaluation value regarding the correlation, a difference in amount of bokeh between the first image and the second image is considered to improve accuracy of the degree of reliability of the motion vector.
