To provide an image playback apparatus that enables an image picked up and
recorded with a wide dynamic range to be changed to the exposure desired
by a viewer. An apparatus that performs image playback by outputting, to
a monitor or printer, image data stored in an image storage unit such as
built-in memory or a memory card, is equipped with a line-of-sight
detection apparatus that detects the line-of-sight direction of the
person viewing the image, or a touch panel, and is configured so that the
area looked at by the viewer is automatically detected, or an arbitrary
part of the screen can be specified by the viewer himself or herself from
the touch panel. At first, conventional dynamic range playback is
performed, then the dynamic range is changed, by changing the tone
conversion curve, etc., for the part where the line-of-sight was detected
within the screen, or the part specified by means of the touch panel, and
a white-skip part or blackening part is reproduced appropriately.
