ABSTRACT:
In a digital camera (10), an imaging sensitivity setting circuit (61) selects a pair of distance range selection parameters “A” and “B” according to a zoom position of a zoom lens (41), to compare an in-focus position of a focusing lens (43) with these parameters “A” and “B”, wherein the parameters “A” and “B” correspond to a farther distance and a nearer distance respectively. If the in-focus position is farther than the parameter “A”, the imaging sensitivity is set to a high level. If the in-focus position is in between these parameters “A” and “B”, the imaging sensitivity is set to a middle level. If the in-focus position is nearer than the parameter “B”, the imaging sensitivity is set to a low level. Based on the set imaging sensitivity level and a measured subject brightness value, a system controller (41) controls the exposure value and the flashlight volume.
