A digital camera has a finder device that enables an optical image which is observable from an observation position and a display image (imaging range frame) of an OLED display to be simultaneously visible by superimposing the display image on the optical image, the digital camera including a system control unit that performs a control of sequentially changing a display position of the display image in the OLED display in a first range, in which a maximum width of the first range is 6 arc-minutes or more and 18 arc-minutes or less in terms of an observation angle (visual angle) in a case where the first range is observed from the observation position.
