。In a camera control device in which an exposure control sequence is executed by an electric circuit driven by a power supply, the power supply voltage is detected before the release operation and start of the camera, and is output only when the voltage is equal to or higher than a predetermined value. voltage detection means for generating a signal; storage means for storing the output signal from the detection means; means for ensuring continuation of the sequence in the electric circuit only when receiving the output from the storage means; and the exposure control. A camera control device comprising: means for detecting the end of a sequence; and means for resetting the guarantee means in response to the output of the sequence end detecting means.
