If an on/off setting of an on-screen display (OSD) on a liquid crystal display (LCD) panel (“LCD OSD” setting) is changed from on to off on an “LCD OSD” setting screen of a menu screen, a system control unit stores a flag A indicating that the “LCD OSD” setting is changed to off into a system memory. If a menu end operation is made and the flag A is stored, the system control unit changes the “LCD OSD” setting to off and ends the menu screen. The setting of the information display on the LCD panel can thereby be made with high operability.
