<p>PROBLEM TO BE SOLVED: To inform a user of the magnitude of a present shake amount by controlling such that the voice frequency of a sounding means changes with outputs from a shake detection means. SOLUTION: A counter is started, and whether or not the counter counted up is decided (S401 and S402). In the case that the counter is found to have counted up, it is the time that the driving frequency of a sounding body is changed. At such a time, the value ofΔV is compared with a 1st reference level V1. In the case ofΔV<V1, it is decided that a camera shake amount is small and the driving frequency of the sounding body is set to f0 (S405 and S406). Meanwhile, in the case ofΔV>=V1, it is compared with a 2nd reference level V2. In the case thatΔV<V2, the driving frequency of the sounding body is set to f1 (S407 and S409). In the case thatΔV>=V2, the driving frequency of the sounding body is set to f2 (S409). By setting the driving frequency of the sounding body to f0, f1 and f2, the next timing to change the frequency of the sounding body is awaited.</p> |
