ストロボ装置及びその制御方法並びにプログラム
Document Type and Number:
Japanese Patent JP7204456
Kind Code:
B2
Abstract:
A strobe device for use with an external camera. Assist continuous light is emitted using first and second LEDs different in color temperature. The color temperature of the assist continuous light is adjusted by either lighting one of the first and second LEDs or simultaneously lighting both at an adjusted light amount ratio. When in a still image pre-check mode, it is determined whether not a color temperature of an ambient light is higher than a threshold value. If the color temperature is higher than the threshold value, the light amount ratio is adjusted such that the light amount of the first LED is larger than that of the second LED, whereas if not, the light amount ratio is adjusted such that the light amount of the second LED is larger than that of the first LED.
