ABSTRACT:
In the automatic exposure control camera disclosed, a memory has data stored therein on the basis of the object brightness and is periodically reset by a reset device to obtain new brightness data, while an exposure control controls exposure on the basis of the data. A signal device ordinarily produces a first signal but locks into a second signal after an external operation. A gate arrangement between the memory and the reset device passes reset signals to the memory, but responds to the second signal to inhibit the reset so as to latch the content of the memory.
