ABSTRACT:
An image pick-up apparatus comprises a distance measuring unit that measures a distance to a subject, and a stroboscope that emits light of an intensity determined based on the measured distance. There are further provided a distance calculating section that calculates a distance to the subject based on the current feed quantity of a focus lens, when the distance measuring unit has failed in the measurement of the distance to the subject, and a light intensity determining section that determines the intensity of light to be emitted from the stroboscope based on the calculated distance.
