Abstract
A camera, at power-on, determines elapsed time since power-off. The camera restores at least one control setting to a persistent value when the elapsed time is less than a predetermined threshold. The camera restores the at least one control setting to a default value when the elapsed time exceeds the predetermined threshold.
