<P>PROBLEM TO BE SOLVED: To provide a technique of an imaging apparatus, capable of surely setting a correction value relating to a photometric value from a photometric sensor which changed, accompanying the exchange of a transparent member, without exerting a load on a user. <P>SOLUTION: The imaging apparatus includes an imaging element and the photometric sensor for receiving the object light which has passed through a focus plate (transparent member) provided exchangeably and performing photometry, and set exposure values and the photometric values for the photometric sensor are compared to execute exposure control. In the state where the exposure control is executed, the photometry is executed, on the basis of image signals obtained in the imaging element, and whether a difference value between the photometric value and the exposure value becomes a threshold α or more is determined (ST9-10). Here, when the difference value becomes the threshold α or larger, it is defined that the focus plate is to be replaced, and the difference value is set as a correction value, relating to the photometric value of the photometric sensor (ST11). As a result, the correction value relating to the photometric value of the photometric sensor changed, accompanying the exchange of the focus plate is surely set without exerting a load on the user. <P>COPYRIGHT: (C)2010,JPO&INPIT |
