1. An image processing device comprising:
at least one memory and at least one processor which function as a plurality of units comprising:
(1) an acquisition unit configured to acquire a second image, obtained by subjecting a pixel of a first image, in which a hand of a user is captured, to correction processing with a correction amount in accordance with a position of the pixel in the first image;
(2) a setting unit configured to (a) acquire a correction amount, corresponding to a position of the hand, among a plurality of correction amounts of the correction processing respectively corresponding to a plurality of pixels of the first image, and (b) set a reduction intensity of noise of the second image in accordance with the acquired correction amount;
(3) a processing unit configured to generate a third image in which the noise of the second image is reduced by the reduction intensity set by the setting unit;
(4) a detection unit configured to detect a region of the hand from the third image; and
(5) a compositing unit configured to generate a composited image by compositing a computer graphics (CG) image and an image of the region of the hand with the third image, with reference to information of the region of the hand detected by the detecting unit.
