Summary:A control unit controls brightness of a liquid crystal display unit such that the brightness becomes darker as a distance between an electronic view finder and an operator measured by a distance measuring sensor becomes shorter. With this structure, even if the operator takes his or her eye off from the electronic view finder, the liquid crystal display unit is not switched from an OFF state to an ON state. Therefore, it is possible to prevent the brightness of the liquid crystal display unit from becoming burdensome to an operator when the eye of the operator approaches the electronic view finder.
