<p>PURPOSE:To prevent a camera from improper learning by making the camera learn an exposure correction value only in the case of setting a learning mode. CONSTITUTION:A proper exposure value EV is decided by the camera by using an exposure arithmetic means 2 based on a photometry value BV which is obtained by a photometry means 1, and a photographer manually corrects the exposure value EV by using an exposure correction value setting means 3 if necessary. The exposure correction value BV4 is not always learned, in the case that the learning mode is set by a learning mode setting means 4, only the exposure correction value BV4 which is used for exposure when the exposure control is actually performed is stored in an exposure correction value storing means 5 so as to be learned. When the exposure is finished and the exposure correction value BV4 is learned, the learning mode is automatically released by a learning mode releasing means 7. Thus, the camera can be prevented from improper learning.</p> |
