<P>PROBLEM TO BE SOLVED: To reduce the occurrence of degradation of resolution performance due to the partial covering state of an ND filter as much as possible, when an imaging apparatus is used in a moving image recording mode, in the imaging apparatus which uses as an exposure adjusting means both a means for adjusting exposure by making the ND filter appear and retreat at/from a diaphragm aperture and a means for at least one different exposure adjustment. <P>SOLUTION: A second exposure adjusting means for driving aperture blades 26a and 26b is controlled in parallel with the fact that a first exposure adjusting means for driving an ND filter 30 makes the ND filter into the partial covering state, to control the opening of the ND filter, when the brightness of an object is in a range above a first level LV1 and below a second level LV2. At this time, an exposure reduction amount by the second exposure adjusting means is decreased while an exposure reduction amount by the first exposure adjusting means is increased, as the brightness of the object is increased. <P>COPYRIGHT: (C)2007,JPO&INPIT |
