1. An image processing apparatus comprising:
one or more processors, wherein the one or more processors function as:
an image input unit configured to input an object image and a reference image which corresponds to the object image and is different in pixel value component type from the object image;
a detection unit configured to detect a detection object candidate region from the object image based on pixel values of the object image;
an extraction unit configured to extract at least one feature from a region of the reference image corresponding to the detection object candidate region; and
an identifying unit configured to identify a noise component region from the detection object candidate region based on the feature.
