1. An image processing device comprising:
a controller comprising a processor or circuit and configured to function as:
a first detection unit that is configured to detect a predetermined object and a predetermined part of the predetermined object from a low-resolution image obtained by reducing a resolution of an acquired captured image;
a setting unit that sets a detection range in the captured image based on a detection result of the first detection unit in a case where (i) the predetermined object has been detected by the first detection unit and (ii) the predetermined part has not been detected by the first detection unit, the detection range being within a region of the predetermined object detected by the first detection unit in the acquired captured image, and the detection range being narrower than the region; and
a second detection unit that attempts to detect the predetermined part in the detection range in the captured image, the resolution of which is higher than that of the low-resolution image.
