An image-taking apparatus performs a correct dimming process while eliminating an influence of flickers in the case of image taking by use of flash light under a flicker light source that exhibits intensity variation of illumination light at a commercial power source frequency of 50 Hz or 60 Hz. A time period of 50 milliseconds is defined as a process cycle as zero points coincide with each other between those of the two frequencies. An amount of light received from an object field is obtained in a first 50-millisecond interval after a full-press action, and an amount of preliminary light emission is obtained in a second 50-millisecond interval. An appropriate amount of light for main light emission is obtained in a third 50-millisecond interval. In this way, main light emission is performed at an accurate amount of light emission.
