Provided are an image processing device, an image capturing apparatus, an image processing method, and an image processing program which can facilitate the visual recognition of a boundary region included in an image for confirming focusing. A generation unit (28B) generates a first display image on the basis of an image signal outputted from an image capturing element, and generates a second display image used for confirming focusing on the basis of first and second images. A correction unit (28C) corrects the gradation of the second display image according to gradation correction information determined on the basis of the spatial frequency characteristic of the second display image and/or the extreme value of the histogram of the pixel values of the second display image. |
