<P>PROBLEM TO BE SOLVED: To perform good diaphragm control for preventing the reduction in image quality according to the amount of incident light. <P>SOLUTION: An imaging apparatus determines a maximum opening value of a diaphragm which is used for diaphragm control, based on information on the focal length and information on the amount of incident light. In the case of focal length being equal, the maximum opening value is relatively increased in a state where the amount of incident light is smaller than in a state where the amount of incident light is larger. <P>COPYRIGHT: (C)2013,JPO&INPIT |
