Abstract
An image processing apparatus includes a motion vector detection unit configured to detect a motion vector at a predetermined space position of a frame at a predetermined time from an input image of a plurality of temporally different frames and obtain a reliability of the motion vector; a motion vector evaluation unit configured to obtain, at each space position, an evaluation value of the motion vector at the space position that is within a predetermined range including a subject space position that is a space position of interest, on the basis of the reliability at the space position and a distance from the subject space position; and a motion vector correction unit configured to correct the motion vector at the subject space position on the basis of the evaluation value and the motion vector at the space position of the predetermined range.
