Abstract
A strobe device and its flashing method for use with an electronic camera of the present invention are such that a preliminary flashlight to set the amount of light of the main flashing is received by a CCD 1, the amount of light of the main flashing is set on the basis of the signal from the CCD 1, the time interval between the preliminary flashing and the main flashing is set to a time that prevents the photographer from recognizing fluctuations in the luminance, and when the interval has exceeded the time, more than one flashing that has nothing to do with the setting of the amount of light of the main flashing is done between the preliminary flashing and the main flashing, thereby preventing the flicker of flashing that gives a sense of incongruity to the photographer.
