Abstract
An image capturing apparatus comprises: an acquisition unit; a smear detection unit; and a smear correction unit which corrects a level of pixels in a smear region in original image data by a first correction amount obtained by multiplying a smear amount by a first coefficient, thereby generating first image data, and corrects the level of pixels in the smear region in the original image data by a second correction amount obtained by multiplying the smear amount by a second coefficient, thereby generating second image data, wherein the first image data is used for at least either of image displaying and image recording, the second image data is used for at least one of exposure control, focus adjustment, and white balance control, and the first coefficient is smaller than the second coefficient.
