ABSTRACT:
When a shutter button is depressed after a stroboscopic image pickup mode is set, an image pickup unit determines a pre-light emission quantity and sends a light emission quantity control pulse to a strobe light emitter to make it carry out a pre-light emission. Then, the image pickup unit detects a light quantity of a picked-up image of an object at the time of the strobe light emission, and determines whether the light quantity is proper or not as the image pickup light quantity. If the light quantity of the image of the object picked up by the pre-light emission is within a range of proper values, the taken-in image is recorded as a photographed image. On the other hand, if the light quantity is not proper, a light quantity necessary for the image pickup is determined based on the light quantity of the taken-in image of the object and makes a strobe carry out a main light emission. Then, the image picked up by the main light emission is taken in and this is recorded as a photographed image. Accordingly, if the light quantity of an image of the object picked up by the pre-light emission is within a range of proper values, it is not necessary to carry out an additional light emission or an image pickup operation.
