<p>An exposure calculating apparatus for a camera having a plurality of processing devices for variously processing photometric outputs from regions of an object field divided into plural sections according to photographic conditions so as to determine the optimum exposure value according to the results of processes performed by the processing devices, the exposure . calculating apparatus for a camera including: a device for setting a plurality of fuzzy rules in the form of membership functions corresponding to the processes performed by the plurality of processing devices; a device for calculating the grade of each of the fuzzy rules according to a plurality of values of photometry generated from photometric outputs from the plurality of regions; a device which selects fuzzy rules having the grades obtained by the calculations so as to calculate, according to the plurality of photometric outputs, exposure values obtained by the processes performed by the processing device which correspond to the selected fuzzy rules; and a device for determining the optimum exposure value by weighting, with the grade, each of the exposure values obtained by the processes performed by the processing device. <IMAGE></p> |
