Abstract
An image capturing apparatus includes: an image capturing unit for capturing an object image; an expander for expanding the dynamic range of the image capturing unit by reducing the exposure of the image capturing unit; a tone correction unit for performing tone correction on image data; a display unit for displaying a display image obtained by the tone correction unit; a detection unit for detecting signal values of a region within a screen of the image capturing unit after the expander expands the dynamic range; and a control unit for, in the case where the dynamic range is expanded, changing a characteristic of tone correction so as to suppress change in the display image caused by the change in the dynamic range.
