发明名称 EXPOSURE CONTROLLER FOR CAMERA
摘要 PURPOSE:To reduce the number of switches and to decrease the number of components by providing an automatic exposure bracket mode driving mode (AEB mode) wherein photographing is performed plural times while an exposure value is varied at the interval of set exposure width. CONSTITUTION:A selecting means selects one of driving modes according to a signal generated every time a 2nd switch means is operated only when a 1st switch means is operated. Further, a varying means varies an exposure correcting value stored in a storage means according to a signal generated every time the 2nd switch means is operated only when a 3rd switch means is operated. Further, when the selecting means is the AEB mode, a photographing control means uses the predetermined exposure correcting value stored in the storage means or exposure correcting value varied by the varying means as the exposure width and the exposure value is varied by this exposure value to perform photographing several times. Consequently, the number of switches can be decreases and the number of components can be decreased.
