An image sensing apparatus includes an image sensor; an image display
device; a display designating unit that designates whether or not the
sensed image is displayed by the image display device; and a focus
evaluating value obtaining device that obtains a focus evaluating value
for adjusting a focus. The focus evaluating value obtaining device
obtains the focus evaluating value based on an image signal that
corresponds to a part of a region of an display image displayed by the
image display device if the display designating unit does not designate
that the sensed image is displayed by the image display device when the
image of the subject is sensed by said image sensor.
