ABSTRACT:
A flash device is provided which causes a plurality of light emitting elements to emit desired white strobe light independent of possible uneven brightnesses of light being emitted by light emitting used. Red, green and blue light emitting elements are driven to emit corresponding colored rays of light to thereby provide white strobe light. Percentages of respective total light emission times of the light emitting elements are determined depending on the percentage data of light being emitted by those light emitting elements and stored in memory.
