Abstract:
1. A digital camera comprising: an imaging device for imaging a subject and outputting an image signal representing a subject image obtained by the imaging; a zoom lens whose focal distance can be changed; a focus lens for focusing; a focus detecting circuit for detecting a focusing position of the focus lens on the basis of integration values of the image signal outputted from said imaging device; distance measurement means for measuring the distance to the subject on the basis of the focusing position of the focus lens detected by the focus detecting circuit; a signal amplifier for amplifying the image signal outputted from said imaging device; first judgment means for judging whether or not the irradiation distance of a strobe which is obtained on the basis of the f-stop value of said zoom lens is shorter than the distance to the subject which is measured by said distance measurement means; and amplification factor control means for increasing the amplification factor of said signal amplifier when said first judgment means judges that the irradiation distance of the strobe is shorter than the distance to the subject.
