To accurately correct the excessive amounts of light of image signals in the stroboscopic photographing of a digital camera to acquire images in which photographed main objects are appropriately bright.

A photographing apparatus has an image pickup device, an electronic flash device and a stroboscopic control means for controlling the electronic flash device. An evaluation value E which indicates the brightness of image signals acquired when photographing using the flash of the electronic flash device is calculated (S412), and then compared with a prescribed reference value which indicates appropriate brightness (S414). If the evaluation value is beyond the prescribed reference one, an amplifying rate of image signals is determined so that the evaluation value satisfies the prescribed reference one, and the image signals are amplified (S416).
