ABSTRACT:
A display device of a camera is automatically switched from a date display mode to a time display mode for a predetermined amount of time in a case when the photographer inputs exposure correction information, such as geographic area information, which involves a correction to account for time change with no change of date. The photographer may thus readily confirm that the time change correction has been made. The order of arrangement of the month, day, and year in the date display mode may be selected automatically according to the geographic area to conform with prevailing custom. The device may incorporate a correction feature to account for daylight saving time and may display a correction code corresponding to the graphic area and a mark indicating that daylight saving time has been selected.
