Provided is a digital camera in which the user can easily recognize that an
image is out of focus by viewing a display image. At the time of live view
display, image capturing is performed every predetermined time in an image
capturing unit 3 and images for live view display are successively
recorded on an image memory 209. An evaluation value computing unit 230 in
an overall control unit 211 obtains an image stored in the image memory
209 and calculates an evaluation value indicative of the focus state of
the image. A display image control unit 240 obtains the evaluation value,
determines a focus state of the image, and controls a process to be
performed by a display image processing unit 250 in accordance with the
result of determination. When the image is out of focus, an image quality
degrading process is performed in the display image processing unit 250
and an image of low image quality is displayed on a display 10.
