摘要:<p>A fully charged battery or an unused battery is set in a battery box of an illumination device. A user turns ON the illumination power of the device and selects the battery set in the battery box. According to an operation button and an instruction on the liquid crystal screen, the user causes a memory in a microcomputer or an IC to store the maximum number of light emission times Smax when a manual full light emission M1/1 is performed by the battery for which the illumination device has been selected. Next, the user performs normal imaging. The light emission (TTL light emission, manual light emission, etc.) amount when the user imaged is converted into manual M1/1 light emission so as to obtain the number of light emission times. The obtained number of light emission times is compared to the maximum number of light emission times Smax so as to calculate how many times the light emission can be performed at maximum.</p>
