<P>PROBLEM TO BE SOLVED: To provide an imaging apparatus which detects an optimal oscillation frequency in a short time, and oscillates an optical member by the frequency. <P>SOLUTION: An imaging apparatus of the present invention is arranged at a subject side of an imaging plane, and includes an optical member which transilluminates light that has passed an image formation optical system; oscillation means to oscillate the optical member; detection means to detect quantity of state indicating a resonant condition of the optical member oscillated by the oscillation means; and control means to perform control in an oscillation mode, in which the oscillation means oscillates the optical member within a prescribed sweep time by gradually changing an oscillation frequency based on a first control parameter, and when the quantity of state exceeds a threshold, the first control parameter is switched to a second control parameter that is different from the first control parameter, and the oscillation means oscillates the optical member by gradually changing the oscillation frequency based on the second control parameter. <P>COPYRIGHT: (C)2012,JPO&INPIT |
