<p>PROBLEM TO BE SOLVED: To provide a method that enables a change of a Tv value or an ISO value after maintaining an exposure to be performed in order upon maintaining the exposure with a Tv value or an ISO value shifted when a full-aperture Av value or a minimum Av value is changed and a setting Av value varies.SOLUTION: An imaging device comprises: upper limit and lower limit setting means of a setting TV value and a setting ISO value; determination means for determining whether there is a change in a full-aperture or a minimum aperture value; means for, when there is the change therein, changing a Tv value so as to be the same exposure value as that before changed; means for, as a result of the determination means, when there is the change therein, changing an ISO value so as to be the same exposure value as that before changed; setting means for, when there is a change, setting whether to change the TV value of the ISO value; and control means for, when changing the TV value, controlling the means for changing the TV value is controlled within a range set by the upper limit and lower limit setting means of the setting TV value, and when changing the ISO value, controlling the means for changing the ISO value within a range set by upper limit and lower limit means of the setting ISO value.</p> |
