Abstract

An image processing apparatus comprises: a feature detection circuit adapted to detect a feature portion of an object from a sensed image; a blur amount detection circuit adapted to detect a blur amount, during image sensing, of a device adapted to obtain the sensed image; a display unit adapted to display the sensed image, and display a frame surrounding the feature portion of the object in the displayed sensed image; and a calculation circuit adapted to set a position, in the sensed image, of the frame surrounding the feature portion of the object, wherein the calculation circuit calculates, on the basis of the blur amount, a moving amount of the frame whose position in the sensed image is set on the basis of the feature portion detected by the feature detection circuit.
