1. An image processing method comprising:
acquiring a captured image obtained by imaging;
generating a first image by correcting a blur component of the captured image; and
generating a second image based on the captured image, the first image, and weight information,
wherein the weight information is generated based on (i) information on brightness of the captured image or information on a scene of the captured image and (ii) information on a saturated area in the captured image,
wherein the information on the saturated area is information indicating a relationship between (i) a range of an area in which an object in the saturated area has been spread by the blur component and (ii) a signal value corresponding to the area,
wherein the weight information is generated based on a third image obtained by a subtraction using the captured image and the information on the saturated area.
