ABSTRACT:
A lighting control apparatus of a photographing apparatus, comprises a lighting-device, and a signal-supplying processor. The lighting-device illuminates a photographic subject by receiving one of a first rectangular wave signal and a second rectangular wave signal. The signal-supplying processor supplies the first rectangular wave signal when the length of an exposure time is less than a predetermined time, and supplies the second rectangular wave signal when the length of the exposure time is equal to or longer than a predetermined time. The first rectangular wave signal has an on state component during the exposure time, and an off state component outside the exposure time. The second rectangular wave signal has a predetermined rising time component when the off state is changed to the on state, and a predetermined falling time component when the on state is changed to the off state, in comparison with the first rectangular wave signal.
