ABSTRACT:
An automatic exposure control apparatus calculates a predicted exposure value to be used at a time of exposure so as to account for predicted movement of an object between a time of photometering values corresponding to respective photometering areas may be weighted based, for example, on the detected movement speed of the object image plane of a phototaking optical system and on the distance to the object substantially at the time of photometering, and the predicted exposure value may then be calculated based on the photometering values as weighted. The weighting of the photometering values may be effected through selecting one of a plurality of possible photometering modes in which different photometering values are used for the exposure value calculation.
