A power source system for a camera includes a primary power source, a secondary power source, a digital logic circuit and a reset circuit. The power source system includes a primary power source connection to connect the primary power source to the digital logic circuit and to the reset circuit, a secondary power source connection to connect the secondary power source to the reset circuit, and a power .source that controls the primary and secondary power source in selectively supplying power to the reset circuit and the digital logic circuit. The power source system permits the digital logic circuit to be reset with certainty.
